Arsenal against FC Porto

Rodriguez passes the ball neatly out of play there. Good technique though.

Vermaelen stops a mazy Falcao run in its tracks. He's been good tonight. As good as Campbell has been poor.

Lovely turn from Song and a nice looking ball for Walcott but Pereira gets there first to concede a corner.

The two subs combine as Denilson feeds Walcott. He tries to replicate his goal against Burnley and isn't far off, but Bruno Alves gets in the way to deflect it behind.

Arsenal change: Arshavin off to a standing ovation and Walcott on.

Porto changes: Varela and Micael go off and Guarin and Gonzalkez comes on.

Arsenal are sitting deep now and allowing Porto to come onto them. A bit of a role reversal from the opening stages.

More cracking work from Arshavin down the left as he gets into the area and stands one up for Sagna to hit on the half volley but he couldn't keep it down.

Nasri comes off to a huge ovation and Denilson comes on.

This has reverted into an Arsenal training session now. Porto need three goals in 20 minutes to go through. Hmm.

Looks like Walcott is ebing readied on the sidelines.

Meireles goes past Nasri and Vermaelen comes out of nowhere to block his shot. Good defending.

How quickly things can turn. Porto had been the better side in this second half, then Arsenal score two world class goals in the space of three minutes. I love this game.

Another truly brilliant goal from Arsenal. What a dazzling counter attack! Arshavin gets the ball in his own half after a Porto corner, dribbles upfield and slips a lovely ball to Eboue who rounds the 'keeper and scores. Game over.

GOAL! Eboue!

An amazing goal burst in Florence too. Viola went 3-1 up before Robben blasts in a beauty just seconds later to swing the tie in Bayern's favour.

What a sensational goal! Nasri's close control there was astonishing. He starts wide on the right and mesmerises three defenders before getting into the area and slamming home from a tight angle. Just brilliant.

GOAL! Nasri!

Hulk gets in yet again down that left channel and Campbell does enough to hasssle him off the ball. Some half decent defending at last from Sol.

Eboue sends Sagna rather wide down the right and his eventual cross is too near Helton. A nervy air hangs over Emirates Stadium.

Off the line! Nasri on the back post gets a thigh on Rodriguez's header from the corner to prevent a certain goal.

Clichy slows down a quick free kick, then shanks the ball behind for a corner after Porto break down the left.

Yellow card for Pereira after a late tackle on Diaby. Bayern have pulled one back in Florence. All square on aggregate.

Hulk skips down the left channel again after Arsenal switch off and drills a ball across the face of goal. Where was his support?

Rosicky is coming off and Eboue is on.

Rodrihuez, who is on for Coelho, brings down Sagna and from the free kick Helton saves Arshavin's powerful effort.

What a chance for Porto! Meireles gets to the byline and pulls it back and Falcao hits it first time but right at Almunia, who scoops the ball up at the second attmept.

Fiorentina have just gone 2-0 up on Bayern. They now lead 3-2 on aggregate.

Song does well to maraud forward, create space and hit a shot but Helton was right behind it.

Rosicky and Song make a mess of things and Hulk has a sight of goal but his shot is high and wide.

By the way, Fiorentina lead Bayern 1-0 in the other tie tonight, meaning they'll go through on away goals if it stays like that.

Raul Meireles has a go from 35 yards out and it was always rising. His team mates don't look too impressed.

Helton gets to Arshavin's inswinging just in time.

Rosicky swings in a free kick and a Porto head flicks it behind for a corner.

Campbell misses his header from an early corner, then Hulk is penalised for handball as a cross drops to him in space.

We're off again...

That's half time and Arsenal deservedly lead 2-0, and 3-1 on aggregate. Porto still look threatening going forward but they are rotten at the back so far. See you in 15 mins.

Nasri cuts inside and fires off a shot from the area and Helton turns it round the corner.

Campbell stretches to intercept Varela's cross. Now Arsenal break...

Three minutes added at the end of the half.

Campbell, again, looks edgy in possession but gratefully wins a throw off Falcao.

Bendtner tries a ridiculous flick, then charges into Fucile with a one-and-a-half footed tackle. He goes in the book.

That is a much better save from Helton. Vermaelen got up at the near post and he was diving backwards, Gordon Banks style, to parry away.

Bendtner goes for his hat-trick after Arshavin's effort but Helton's save prevents him.

Hulk tries to dazzle Clichy with some Ronaldo style trickery but the defender blocks his cross.

Porto's first real spell in the game here. Arsenal need to be careful to get to half time without conceding.

Hulk reads the flight of the ball better than Clichy and he is away down the right. He got into the area and went for goal when he should have pulled it back for Falcao. Poor decision.

Vermaelen gets a yellow card for pinching the ball off Falcao from behind. Falcao makes the point to the ref that he got booked for a similar offence and out came the cared.

Decent spell from Porto here as Sagna deflects Perreira's cross behind for another corner.

Varela gets to the byline and wins a corner off Sagna. Roland and Bruno Alves come up for it.

Excellent tackle from Sagna as Meireles tries to jink down the left flank.

What a miss! Nasri gets to the byline, pulls the ball across and Arshavin is standing ten yards out, at a slight angle but with an open goal ... and he blazes it over the bar.

The Hulk gets a sight of goal as Almunia clears right to his feet about 40 yards out. His effort is curling but wide.

Varela has a run down the left but his cross is weak and easily collected by ALmunia.

Arshavin finds Bendtner again but this time the Dane is offside. By a mile. Great work from Song to start the move though.

Campbell gets out of jail again. As the defender miscontrolled a long ball the striker had just come from an offside position but was flagged as soon as he made a tackle. Odd.

Arsenal win a free kick on the left edge of the penalty area and Arshavin goes for the top corner but his effort lacked pace.

Nasri hobbled off for treatment after the goal but he's back on now.

Awful defending from Porto for the last goal. Fucile had no reason to give the ball away and Bendtner was completely alone as the cross came in. He was also a yard behind Arshavin as he crossed so he couldn't be flagged offside.

Arshavin is the architect again! He twists and turns into the box after Fucile gave the ball away, and as he bangs it across goal, Bendtner is there to turn the ball into an empty net.

GOAL! Bendtner!

Song and Falcao collapse in a heap after the Porto player slides in from behind. He gets the night's first yellow card.

Hulk tires to flick on to Falcao but Vermaelen is there. Porto look dangerous in possession.

Superb ball across the face from Arshavin but no-one was there to turn it in. A great pace to this game.

A terrible header from Campbell, who had time to bring the ball down but instead gave it straight to Falcao. Luckily for him Song was on hand.

Falcao does well to get the better of Campbell and unloads a shot but Vermaelen blocks well. Then Porto retrieve the ball and win a corner that Almunia is forced to clear with a flying punch.

Diaby meets the corner on the volley and tries to direct it towards the top corner but it flashes over the bar. Difficult chance and a good effort.

The Gunners break downfield and as always the full backs are up in support. Sagna wins a corner off Pereira.

Arsenal gifting possession to Porto after two dangerous crosses came into the box. Coelho missed a bouncing ball in the box but it was a tough chance.

Porto's first attack of note as Hulk looked to come in onto his left foot. Campbell blocked, then Arshavin gave the ball away and Porto have a corner.

Helton's first involvement after his knock is to collect an Arshavin cross from the left.

Finally, we restart....

Rolando has to take a big share of the blame for that goal. The centre back lost out in the air to Arshavin, then the Russian ran into the space behind him to create the goal. Helton is on his feet now, but looks groggy.

As it stands, Arsenal are going through on away goals. Helton is still down after the collision, but it wasn't a foul on him, just an honest clash for the ball.

Super ball from Nasri through the middle for Arshavin, the 'keeper comes out and after the ball squirms free. Bendtner pokes out a leg and sticks it into the net. He does know where the goal is after all!

GOAL! Bendtner!

Porto look to break but Song breaks it up. Lightning opening from Arsenal, Porto firmly under the kosh.

Great football again from Arsenal as Rosicky spreads it wide for Sagna, his cross finds Arshavin at the back stick but Helton parries behind for a corner.

Good Arsenal move, Nasri feeds Rosicky, his cross is blocked but then Nasri pops up and has a go but Coelho gets a great block in.

Sagna gets a whack on the ankle after stretching to win the ball against Pereira. Looks more of an impact injury than any thing more serious.

Lovely inswinging ball from Arshavin but Helton is out to punch clear, as is the continental way.

Typical Arsenal build up play outside the area, looking for the magic pass to unlock the defence. Arshavin tries to feed Diaby but Rolando is there.

A decent ball into the box from Clichy but Bendtner misses his header. Then Rosicky's second ball is out of play.

An early ball into the box from Fucile but Campbell heads clear.

We're off...

Arsenal have never managed to overturn a first leg deficit in the Champions League would you believe.

Arsenal will, of course, pour forward, but as Arsene Wenger has just said in his pre-match interview, the Gunners must be wary about the counter attack. Porto are no mugs at all, and definitely have a goal in them. Sol Campbell is still a worry in defence for me.

FC Porto: Helton, Fucile, Rolando, Bruno Alves, Pereira, Ruben Micael, Coelho, Raul Meireles, Varela, Falcao, Hulk. Subs: Nuno, Guarin, Belluschi, Rodriguez, Gonzalez, Maicon, Miguel Lopes.

Arsenal: Almunia, Sagna, Campbell, Vermaelen, Clichy, Nasri, Song, Diaby, Rosicky, Bendtner, Arshavin. Subs: Fabianski, Eduardo, Walcott, Denilson, Silvestre, Eboue, Traore.

Cesc Fabregas is missing of course, after he picked up a knock against Burnley on Saturday. Here are the teams...

Good evening one and all and welcome to live commentary on Arsenal's Champions League tie with Porto. The Gunners trail 2-1 from the first leg, and the goals they conceded were atrocious.
