Barcelona against Chelsea

The ball was in the Barcelona box, but then it was hammered up the other end and Torres found himself free. He took it round Valdes and made it 2-2.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/goal.gif"> <b>GOAL</b> Torres scores! Incredible stuff.

Tello loses the ball and it's booted upfield. So tense. Can they do it?

Puyol with the header over and we're into added time. 3 minutes of stoppage time.

Messi curls it in, but Ivanovic is there to head out. Mascherano smashes it from distance and Cech palms it behind.

If they do make it, the youth squad will be delighted. Most of them will be playing.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/yellow_card.jpg" height="15"> Meireles is booked and now he's out of the final as well.

Messi and Keita fail to combine and Cech has the ball safely. A punt upfield and here we go again.

Time running out now and Pep Guardiola is running around on the sidelines directing the troops. It would be a monumental effort from the Blues if they can hold on for five minutes.

Messi is running at the defence again. He is being harried, but Cole gets ball away before he could penetrate.

Bosingwa heads clear from Alves' cross. Torres is not doing his job down the Chelsea left.

Messi gives the ball away and is looking tired. That might have been his last effort. Barca building, but the wall is still there.

Torres was one-on-one with Mascherano, but he lost control of the ball. That was a really good chance for a fresh player.

Wow that was close. Are the football Gods smiling on the Blues tonight? Cech might just have got some fingertips on that one.

Messi hits the post. The best player in the world cuts inside and hammers it past Cech. It slams off the woodwork.

It's in the net from Sanchez, but Alves was offside. Torres left him, but he was just off.

Keita is almost playing as a striker here, as the ball is floated in to him again. Barca look like they might be out of ideas.

Torres needs to do his defensive duty as well: Stop Alves down the right.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/subs.gif"> Drogba off, Torres comes on. A bit of pace and energy up front could kill off the game.

Tello takes on Kalou, but the Chelsea man comes out on top. Impressive defending. This is starting to become a real effort from the Blues.

Barca crossing with few tall enough to make an impact in the box. But they will continue to try and make space as best they can.

Iniesta's ball in is headed out and Busquets has it in space on the edge of the area. He can't control the volley and it flies over.

Iniesta tries a shot, and there needs to be more of that. A deflection or something could win this game.

Mascherano has to scamper back to stop Ramires after a sloppy ball from Kalou. The Blues still have a chance on the break.

Drogba back to defend and it's all hands to the pump. So many players in the Chelsea box. Hard to see how Barca can make space.

Keita's first touch is a blocked shot in the box. Good movement, but it was well marshalled.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/subs.gif"> Fabregas off, Keita on.

Messi and Iniesta combine and the shot is blocked. Xavi also has a shot blocked and Kalou is back defending. Barca looking dangerous, but there is a wall in front of them.

Chelsea's back five are doing well to keep on top of the Barca attacks and are hoofing the ball clear at every chance.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/yellow_card.jpg" height="15"> Lampard now in the book. A tough tackle on Fabregas and it was very late.

Not often you see the little man get booked, but it's a sign of Barca's frustration. They can't seem to break down the Blues.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/yellow_card.jpg" height="15"> Messi booked. He lost the ball to Lampard and hauled him down when he was breaking away.

Last 20 minutes and Barcelona need to score; Chelsea must hold on.

Drogba is down and hurt(?). Barca didn't put the ball out, but they didn't have to as they are well aware of his tricks. The Blues are annoyed though.

What a ball from Lampard, he turned it around the corner for Kalou and the defence was split. He dithered on the ball and Valdes came out to block. Another great chance for the ten-man Blues to kill this off.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/subs.gif"> Cuenca off and Tello comes on. He had a poor game v Real Madrid so will want to impress.

Drogba gets it off Alves and he seems to be the best defender of the lot.

Alves chips it in, but Ramires is there to head behind as Fabregas was closing in.

Barca are still working their passes around the box, but Chelsea are standing firm.

Remember that moment. If Barca win, then Ivanovic will hang his head more than most. (Perhaps not JT though).

Drogba does well to win a corner. There's only three players in there and Ivanovic gets his head on it. Oh, he was free! It comes off his shoulder and that could have been game over!

The corner comes in and Puyol is free. His header is really poor though and loops up instead of finding the target.

Great passing again. The ball finds Iniesta, who slips it to Cuenca and the youngster hits his shot right at Cech. He did well to come out and block.

Cuenca beats Ramires and his ball in is cleared in front of Cech by Ivanovic.

Sanchez is there again in the box, but Chelsea keep him out and it's another goal kick. He took it a bit quicker now. Not sure Chelsea could cope with nine men.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/yellow_card.jpg" height="15"> Cech goes in the book for timewasting. That's the crowd helping out the ref there.

Lampard's kick flies up in the air and Puyol heads over.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/subs.gif"> Mata off, Kalou on. Pace is required over guile it seems.

Poor from Busquets and Barca lose the ball. Nothing Chelsea can do to break forward though. Drogba gets the ball and charges down the right. He hammers a shot from inside his own half and Valdes saves (just).

Iniesta tries a low ball which is hit away by Ivanovic. Barca turning up the gas now.

Great ball to Alves, who crosses and Sanchez is there to head the ball. It goes wide, and perhaps he should have done better as he had found space between the defenders.

Ramires has the ball and there is no-one to pass to up front.

No bookings there though, which is a little odd.

Now there's a fight, of course there is. Fabregas and Lampard are at it against - remember the 2007 Carling Cup final? - Messi pushes Lamps and everyone piles in.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/yellow_card.jpg" height="15"> Ivanovic was booked earlier, for protesting over the penalty. He would miss the final.

We'll get more from that later on. There will be some more quotes, but there is more of a game to come.

Terry says: "I've not had one booking this UCL season, and I did not do it deliberately."

Messi charges through and is almost tripped, but stands on his feet. Bosingwa gets it clear.

What a game, is everything going to happen???

He hits the bar! Incredible!

Not much contact, but enough and Barca have a great chance right away. Messi steps up...

<B>PENALTY!</B> Drogba was tricked by a one-two and Fabregas went down.

<img src="http://soccernet-assets.espn.go.com/design05/images/2012/0424/ramiresgoal20120424_275x155.jpg"><br>Ramires chips the ball home to make it 2-1.

Well that was close. Iniesta's shot is blocked as Fabregas turned it onto him. Just squeaked wide.

Barcelona are doing their thing already. But they do need to score, they can't keep holding onto it.

<b>KICK-OFF</b>: Barcelona get us underway for the second half.

Can the Blues hold on and make the next 45 minutes the greatest of their careers? We'll find out shortly.

<img src="http://soccernet-assets.espn.go.com/design05/images/2012/0424/sergiobusquetsgoal20120424_275x155.jpg"><br>Sergio Busquets turns the ball home for the opening goal

Nobody seems to have any idea what Terry was doing. We can't wait to hear from the man himself.

<img src="http://soccernet-assets.espn.go.com/design05/images/2012/0424/johnterryredcardargument20120424_275x155.jpg"><br>Petr Cech looks to calm John Terry down after his first-half dismissal

The focus will be on John Terry and what he did. A simple knee to Sanchez that he thought nobody would see. The assistant ref did though, and he deserved a red card for such a stupid act.

What an incredible half of football. Ramires' goal with only a few seconds of the first-half left has opened things up again.

<b>HALF-TIME: Barcelona 2-1 Chelsea</b>. Terry's red card has handed Barca the advantage, but they will need to score again in the second half.

Cuenca's cross and Bosingwa gets it over the bar. Cech has committed and for a second it looked like it might go in.

Well, that is interesting. Chelsea are through on away goals now and Barcelona need to score one more.

What a finish. Lampard releases him as Barca switched off and he chips the ball over Valdes superbly.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/goal.gif"> <b>GOAL</b> What a goal! Ramires out of nowhere!

Sanchez has it in the box and Cole has to get his foot on the ball to stop Barca again.

A killer blow for the Blues. They just opened up and the defence was caught out by Messi's pass.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/yellow_card.jpg" height="15"> Ramires goes into the book for protesting and would miss the final.

A wonderful finish and surely there is no way back for the Blues.

Busquets robs the ball and Sanchez breaks. He runs at the defence and they retreat. Messi is there and he passes left to Iniesta who slots it home.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/goal.gif"> <b>GOAL</b> Iniesta scores another for Barcelona.

Sanchez with a clever turn in the box. Bosingwa has now moved into the centre of defence and Ramires at RB.

Cuenca set up the goal, but that was from the other side. Cole has controlled him all game.

Drogba is dropping back and helping out. Chelsea need to get to half-time without another goal or losing their cool.

A rearguard action is all that is left. Forget Chelsea's attacks now; they'll be holding on for penalties.

No skipper and no central defenders: Mikel has slotted in there. Chelsea are going to have a real struggle on their hands.

Xavi flicks the free-kick back to Messi, who blasts it into the wall.

Evidently the assistant ref drew the referee's attention to the incident from Terry.

What are Chelsea going to do now? They have no more defenders on the bench.

Terry is furious, but it was a blatent kick out. He thought the ref wouldn't see it, but he did.

An off the ball incident and Sanchez has gone to ground. He kneed him in the hamstring. Quite obvious to me.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/red_card.jpg" height="15"> John Terry has been sent off.

Lots of great goalscorers for Barca and the DM Busquets is the one who slots home. 1-0 Barca.

It was a corner that was hit out, Alves pounced and fed Cuenca who slotted it across the box. Busquets was there to hit home from six yards out. Very easy.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/goal.gif"> <b>GOAL</b> Busquets scores!

<img src="http://soccernet-assets.espn.go.com/design05/images/2012/0424/gerardpiqueinjury20120424_275x155.jpg"><br>Carles Puyol calls for medical attention as Gerard Pique suffers a nasty fall

Cech being booed for 'timewasting' from goalkicks. Ref is telling him to get on with it, but the Barca fans are showing their frustrations.

Cuenca is being marshalled well by Cole and has found little space. A pass was on to Iniesta, but Fabregas overhits it and it goes beyond him.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/yellow_card.jpg" height="15"> Mikel is booked for bringing down Sanchez.

A long ball again down the middle. Valdes panics and miscommunicates with Puyol. He ends up slicing his kick with Mata bearing down.

Now the ball rebounds back to Iniesta, and his shot flies wide. So far the long shots have done little to trouble Cech.

Sanchez is causing Ivanovic some issues, he pops it back to Xavi who has a shot which is blocked.

Cech has remained untested since the Messi effort; Chelsea will certainly be happy with that.

Busquets is helping out his defence and picks the pocket of Drogba after he brought the ball down well.

Cuenca's cross beats everyone, while Sanchez picked it up and Messi tried a lobbed pass. Ivanovic cut it out though.

Puyol goes for the corner and Drogba heads clear. Good defending as well from the Ivorian.

Chelsea strong again as the little passes outside the box come. Iniesta can't get past Bosingwa, who stands firm and doesn't let him past.

<img src="http://soccernet-assets.espn.go.com/design05/images/2012/0424/garycahillphysio20120424_275x155.jpg"><br>Gary Cahill speaks to the Chelsea medical staff after sustaining an injury

A bit of a tactical shift now, and Mascherano moves into the centre with Alves on the right of the 3-4-3.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/subs.gif"> Pique off, Alves on. He was struggling after that head blow.

One huge long ball from Cech finds Drogba. He muscles his way past Pique and shoots wide of the near post. Contrast of styles there.

Close control again as Messi drops off and tries to pass between Cesc and Sanchez. It's all too tight though.

Drogba with a flick on and he gets the ball back from Ramires. A volley on the turn lacks venom and flies carelessly over the bar.

Drogba making a nuisance of himself again. Clashing with Busquets and the ref has to seperate them.

Chelsea will be happy if they are reduced to shooting from that far out. It's the interplay around the box that will cause them problems.

Barca knocking it around again, but it's all in front of 11 Chelsea players. Mascherano shows his skills and has a go from way out, but it flies over.

Cuenca hit the side netting soon after as Barca went on the attack again. They look the more likely to score at the moment.

Messi should do better, he's had two chances on goal now and missed them both. Best chance of the half so far.

Barca with a wonderful move. Another one-two and a backheel from Fabregas to Messi. He hits it, but Cech blocks with his feet.

Pique is back on by the way.

Drogba flicks the ball on and Mascherano has to clear. He's going to be a tough prospect up front all night.

Pique is up on his feet, but looks very shaky. Barca could be called into a sub.

The defender has taken a real blow to the head. Valdes' hip clocked him and he's down. Medical staff are on the pitch and attending to him.

Cech hammers the ball upfield and Drogba is running onto it. Valdes comes out and takes him and Pique out. Pique is spark out.

Bosingwa shows a poor touch and gives it to Fabregas. He's drifting around, but has not done too much of note so far.

Chelsea getting a bit of the ball back now. They don't need a goal, but they would love one.

Mata wastes a chance to get the ball to Drogba, as his cross is too close to Valdes.

Pass, pass, pass, we've seen it before. But how much longer can Chelsea hold out?

Barca looking for an opening. Moving it nicely from side to side, but there are 21 players in the Chelsea half.

Ivanovic to move to centre-back and the Portuguese will slot in on the right of defence.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/subs.gif"> Cahill off, Bosingwa on. Huge disappointment for the Chelsea defender.

Messi and Sanchez look to link up again, but the ball rebounds and Xavi almost makes the most of it.

So many players in the Chelsea box, it's really congested. Barca are playing their usual way, Chelsea trying to get bodies behind the ball.

Iniesta flicks the ball over the heads of the defenders after finding space down the left and Cole has to clear from under his bar. Cech was nowhere.

Looked like Cahill was about to come off, but he's staying out there and Bosingwa has gone to sit down again.

Drogba cutting a lone figure up front. Hardly seen much of him at all.

Barca playing against ten men for the time being and are keeping the ball well. Cech comes to claim well after a lofted pass from Messi.

Cahill is up and about again, but Bosingwa is warming up on the sidelines.

He overstretched and has gone down. The fans are shouting for timewasting, but that doesn't look good; a hamstring strain perhaps?

Sanchez again causing problems as Messi exchanges passes. The ball is slipped to him but Cahill is there to block. Really quick feet from the Barca frontline and they look dangerous. Cahill has pulled something and looks hurt.

Chelsea have dropped back, unsurprisingly. Barca with some trademark passing trying to open a gap or two.

Cuenca is working Cole down the Barca right. Terry does well to get his foot on the cross and clears.

<img src="http://soccernet-assets.espn.go.com/design05/images/2012/0424/barcelonapre-matchhuddle20120424_275x155.jpg"><br>Barcelona players huddle ahead of the kick-off.

Reminding you again: Messi has never scored against Chelsea.

Messi with a wonderful chance. Passes one-two with Sanchez and races through. He's a little wide and his shot misses the near post on his weaker right foot.

Xavi with a dink over the top and Sanchez races onto it. The ball skids off the turf and through to Cech.

Cahill up in the opposition box for a free-kick, but is beaten to the ball. I guess Chelsea aren't all about defending after all.

That was an early scare with about 10 seconds on the clock. Barca now keeping possession and making sure they control the pace.

Cole gets away down the left right away and slipped the ball inside to Ramires. He almost got onto it, but Valdes came out.

<B>KICK-OFF</B>: Chelsea get us underway...

Cuneyt Cakir from Turkey is the official, one of UEFA's least experienced. He is going to be watched closely.

The players are in the tunnel and ready to go. Chelsea have drawn the last three times they have been at the Nou Camp and they would love to do it again.

Just five minutes to kick-off and it's starting to get exciting now. Am sure Roman is as nervous as anyone.

And one that really is amazing. Victor Valdes has made just 9 saves in the competition this season; Petr Cech has made 43.

However, Chelsea are the team Lionel Messi has played the most against in the Champions League without scoring: six games, no goals.

Want some stats: Under Pep Guardiola, Barcelona have only failed to score twice in 24 knockout games in the Champions League (against Chelsea & AC Milan)

The first goal will be key: If Chelsea can grab one they I think they will sit and try and hold on. If Barca get it, then we may see Di Matteo move more to a 4-2-3-1.

You have to remember Barca's finishing was poor as well, but they are a wounded animal after the Clasico defeat so Chelsea certainly have a chance.

Guardiola's tactics were off in the first leg as Messi was isolated. With Sanchez and Cuenca up there now, he can drop off and use the space better with the defenders preoccupied.

<i>Syed asks: Jon, do you think that #CFC strategy of defending all out is a bad one?</i> Yes, they can't invite pressure the whole time and will need an outlet. Drogba will be key there.

Certainly they will fancy Drogba to have another go at the defence, along with Mata pulling the strings in behind. First job, though, is defence and it will be a hard one for Barca to get through.

Any questions for me, then I'm on Twitter <a href="https://twitter.com/#!/joncarterespn" target="_blank">@joncarterespn</a>.

So Barcelona out to attack then. They need to as a 0-0 will send Chelsea through. The Blues are in with a massive chance if they score, as Barca will need to get three.

Chelsea will defend in a 4-5-1: Cech; Ivanovic, Cahill, Terry, Cole; Lampard, Mikel, Ramires, Meireles, Mata; Drogba.

Barcelona team news, and it's 3-4-3. Valdes, Pique, Mascherano, Puyol; Busquets, Xavi, Fabregas, Cuenca; Messi, Sanchez, Iniesta.

There are five players who <a href="/design05/images/2012/0404/robertodimatteobenficavchelsea20120404_275x155.jpg" target="_blank">could miss the final</a> if they pick up yellow cards. But Chelsea are not worried; the team comes first.

Join us for all the action as Chelsea travel to Barcelona with a 1-0 lead in the Champions League semi-finals.

Busquets robs the ball and Sanchez breaks. He runs at the defence and they retreat. Messi is there and he passes left to Iniesta who slots it home.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/goal.gif"> <b>GOAL</b> Iniesta scores another for Barcelona.

Sanchez with a clever turn in the box. Bosingwa has now moved into the centre of defence and Ramires at RB.

Cuenca set up the goal, but that was from the other side. Cole has controlled him all game.

Drogba is dropping back and helping out. Chelsea need to get to half-time without another goal or losing their cool.

A rearguard action is all that is left. Forget Chelsea's attacks now; they'll be holding on for penalties.

No skipper and no central defenders: Mikel has slotted in there. Chelsea are going to have a real struggle on their hands.

Xavi flicks the free-kick back to Messi, who blasts it into the wall.

Evidently the assistant ref drew the referee's attention to the incident from Terry.

What are Chelsea going to do now? They have no more defenders on the bench.

Terry is furious, but it was a blatent kick out. He thought the ref wouldn't see it, but he did.

An off the ball incident and Sanchez has gone to ground. He kneed him in the hamstring. Quite obvious to me.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/red_card.jpg" height="15"> John Terry has been sent off.

Lots of great goalscorers for Barca and the DM Busquets is the one who slots home. 1-0 Barca.

It was a corner that was hit out, Alves pounced and fed Cuenca who slotted it across the box. Busquets was there to hit home from six yards out. Very easy.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/goal.gif"> <b>GOAL</b> Busquets scores!

Cech being booed for 'timewasting' from goalkicks. Ref is telling him to get on with it, but the Barca fans are showing their frustrations.

Cuenca is being marshalled well by Cole and has found little space. A pass was on to Iniesta, but Fabregas overhits it and it goes beyond him.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/yellow_card.jpg" height="15"> Mikel is booked for bringing down Sanchez.

A long ball again down the middle. Valdes panics and miscommunicates with Puyol. He ends up slicing his kick with Mata bearing down.

Now the ball rebounds back to Iniesta, and his shot flies wide. So far the long shots have done little to trouble Cech.

Sanchez is causing Ivanovic some issues, he pops it back to Xavi who has a shot which is blocked.

Cech has remained untested since the Messi effort; Chelsea will certainly be happy with that.

Busquets is helping out his defence and picks the pocket of Drogba after he brought the ball down well.

Cuenca's cross beats everyone, while Sanchez picked it up and Messi tried a lobbed pass. Ivanovic cut it out though.

Puyol goes for the corner and Drogba heads clear. Good defending as well from the Ivorian.

Chelsea strong again as the little passes outside the box come. Iniesta can't get past Bosingwa, who stands firm and doesn't let him past.

<img src="http://soccernet-assets.espn.go.com/design05/images/2012/0424/garycahillphysio20120424_275x155.jpg"><br>Gary Cahill speaks to the Chelsea medical staff after sustaining an injury

A bit of a tactical shift now, and Mascherano moves into the centre with Alves on the right of the 3-4-3.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/subs.gif"> Pique off, Alves on. He was struggling after that head blow.

One huge long ball from Cech finds Drogba. He muscles his way past Pique and shoots wide of the near post. Contrast of styles there.

Close control again as Messi drops off and tries to pass between Cesc and Sanchez. It's all too tight though.

Drogba with a flick on and he gets the ball back from Ramires. A volley on the turn lacks venom and flies carelessly over the bar.

Drogba making a nuisance of himself again. Clashing with Busquets and the ref has to seperate them.

Chelsea will be happy if they are reduced to shooting from that far out. It's the interplay around the box that will cause them problems.

Barca knocking it around again, but it's all in front of 11 Chelsea players. Mascherano shows his skills and has a go from way out, but it flies over.

Cuenca hit the side netting soon after as Barca went on the attack again. They look the more likely to score at the moment.

Messi should do better, he's had two chances on goal now and missed them both. Best chance of the half so far.

Barca with a wonderful move. Another one-two and a backheel from Fabregas to Messi. He hits it, but Cech blocks with his feet.

Pique is back on by the way.

Drogba flicks the ball on and Mascherano has to clear. He's going to be a tough prospect up front all night.

Pique is up on his feet, but looks very shaky. Barca could be called into a sub.

The defender has taken a real blow to the head. Valdes' hip clocked him and he's down. Medical staff are on the pitch and attending to him.

Cech hammers the ball upfield and Drogba is running onto it. Valdes comes out and takes him and Pique out. Pique is spark out.

Bosingwa shows a poor touch and gives it to Fabregas. He's drifting around, but has not done too much of note so far.

Chelsea getting a bit of the ball back now. They don't need a goal, but they would love one.

Mata wastes a chance to get the ball to Drogba, as his cross is too close to Valdes.

Pass, pass, pass, we've seen it before. But how much longer can Chelsea hold out?

Barca looking for an opening. Moving it nicely from side to side, but there are 21 players in the Chelsea half.

Ivanovic to move to centre-back and the Portuguese will slot in on the right of defence.

<img src="http://soccernet-assets.espn.go.com/design05/gp10/i/subs.gif"> Cahill off, Bosingwa on. Huge disappointment for the Chelsea defender.

Messi and Sanchez look to link up again, but the ball rebounds and Xavi almost makes the most of it.

So many players in the Chelsea box, it's really congested. Barca are playing their usual way, Chelsea trying to get bodies behind the ball.

Iniesta flicks the ball over the heads of the defenders after finding space down the left and Cole has to clear from under his bar. Cech was nowhere.

Looked like Cahill was about to come off, but he's staying out there and Bosingwa has gone to sit down again.

Drogba cutting a lone figure up front. Hardly seen much of him at all.

Barca playing against ten men for the time being and are keeping the ball well. Cech comes to claim well after a lofted pass from Messi.

Cahill is up and about again, but Bosingwa is warming up on the sidelines.

He overstretched and has gone down. The fans are shouting for timewasting, but that doesn't look good; a hamstring strain perhaps?

Sanchez again causing problems as Messi exchanges passes. The ball is slipped to him but Cahill is there to block. Really quick feet from the Barca frontline and they look dangerous. Cahill has pulled something and looks hurt.

Chelsea have dropped back, unsurprisingly. Barca with some trademark passing trying to open a gap or two.

Cuenca is working Cole down the Barca right. Terry does well to get his foot on the cross and clears.

<img src="http://soccernet-assets.espn.go.com/design05/images/2012/0424/barcelonapre-matchhuddle20120424_275x155.jpg"><br>Barcelona players huddle ahead of the kick-off.

Reminding you again: Messi has never scored against Chelsea.

Messi with a wonderful chance. Passes one-two with Sanchez and races through. He's a little wide and his shot misses the near post on his weaker right foot.

Xavi with a dink over the top and Sanchez races onto it. The ball skids off the turf and through to Cech.

Cahill up in the opposition box for a free-kick, but is beaten to the ball. I guess Chelsea aren't all about defending after all.

That was an early scare with about 10 seconds on the clock. Barca now keeping possession and making sure they control the pace.

Cole gets away down the left right away and slipped the ball inside to Ramires. He almost got onto it, but Valdes came out.

<B>KICK-OFF</B>: Chelsea get us underway...

Cuneyt Cakir from Turkey is the official, one of UEFA's least experienced. He is going to be watched closely.

The players are in the tunnel and ready to go. Chelsea have drawn the last three times they have been at the Nou Camp and they would love to do it again.

Just five minutes to kick-off and it's starting to get exciting now. Am sure Roman is as nervous as anyone.

And one that really is amazing. Victor Valdes has made just 9 saves in the competition this season; Petr Cech has made 43.

However, Chelsea are the team Lionel Messi has played the most against in the Champions League without scoring: six games, no goals.

Want some stats: Under Pep Guardiola, Barcelona have only failed to score twice in 24 knockout games in the Champions League (against Chelsea & AC Milan)

The first goal will be key: If Chelsea can grab one they I think they will sit and try and hold on. If Barca get it, then we may see Di Matteo move more to a 4-2-3-1.

You have to remember Barca's finishing was poor as well, but they are a wounded animal after the Clasico defeat so Chelsea certainly have a chance.

Guardiola's tactics were off in the first leg as Messi was isolated. With Sanchez and Cuenca up there now, he can drop off and use the space better with the defenders preoccupied.

<i>Syed asks: Jon, do you think that #CFC strategy of defending all out is a bad one?</i> Yes, they can't invite pressure the whole time and will need an outlet. Drogba will be key there.

Certainly they will fancy Drogba to have another go at the defence, along with Mata pulling the strings in behind. First job, though, is defence and it will be a hard one for Barca to get through.

Any questions for me, then I'm on Twitter <a href="https://twitter.com/#!/joncarterespn" target="_blank">@joncarterespn</a>.

So Barcelona out to attack then. They need to as a 0-0 will send Chelsea through. The Blues are in with a massive chance if they score, as Barca will need to get three.

Chelsea will defend in a 4-5-1: Cech; Ivanovic, Cahill, Terry, Cole; Lampard, Mikel, Ramires, Meireles, Mata; Drogba.

Barcelona team news, and it's 3-4-3. Valdes, Pique, Mascherano, Puyol; Busquets, Xavi, Fabregas, Cuenca; Messi, Sanchez, Iniesta.

There are five players who <a href="/design05/images/2012/0404/robertodimatteobenficavchelsea20120404_275x155.jpg" target="_blank">could miss the final</a> if they pick up yellow cards. But Chelsea are not worried; the team comes first.

Join us for all the action as Chelsea travel to Barcelona with a 1-0 lead in the Champions League semi-finals.
