That's all from me on the text commentary but stay online for our post-match show. Dan Roebuck and Martin Hayes will be taking your calls as well as your e-mails so phone the studio on 020 7607 3200 (from inside the UK) or +44 20 7607 3200 (from outside the UK).
90
HENRY IS IN THE CENTRE CIRCLE: He's getting a rapturous reception and applauding the Arsenal fans. Lovely scenes.
90
IT'S ALL OVER HERE AT THE EMIRATES: And what a game we've seen. The first half was a Barca masterclass and they got the goals they deserved early in the second half through Ibrahimovic. But Arsenal fought like lions to peg the visitors back through Walcott and then Fabregas' penalty. Breathless stuff.
Full Time FULL-TIME: ARSENAL 2 BARCELONA 2
90
ARSENAL LOOK KNACKERED: They have chased Barca for so much of this game, it has been a super-human effort to peg them back.
90
REMINDER: Stay online after the final whistle for our post-match show. Dan Roebuck and Martin Hayes will be taking your calls as well as your e-mails so phone the studio on 020 7607 3200 (from inside the UK) or +44 20 7607 3200 (from outside the UK).
90
WALCOTT CROSSES TOWARDS NASRI... but Valdes comes out and claims.
90
BARCA STILL DANGEROUS ON THE BREAK... but Arsenal are seeing more of the ball.
90
WE'RE INTO THE FINAL MINUTE OF NORMAL TIME: And the crowd are roaring their team on. Can Arsenal find a winner?
87
CESC IS BACK ON THE PITCH. So it's 11 against 10 for the last few minutes. But frankly it's more like 10 v 10 because he is virtually a passenger.
87
Substitution SUB: Messi is replaced by Milito as Barca fill the hole left by Puyol's sending off
85
CESC SLAMS IT INTO THE NET AND WE ARE ALL-SQUARE! Incredible scenes at the Emirates! But hang on - Cesc is injured and a stretcher is coming out for him. Highs and lows all the way.
85
GOAL! - Cesc Fabregas 2 : 2 GOAL!!! ARSENAL 2 BARCELONA 2
84
Red Card RED CARD: Puyol is sent off for denying a clear goalscoring chance. Wow! What a chance for Arsenal!
84
PENALTY TO ARSENAL! Cesc is brought down by Puyol!
83
ARSENAL STILL PRESSING: Barca seem happy to let them have the ball and try to hit them on the counter-attack.
81
WALCOTT FINDS EBOUE IN THE BOX: But Puyol comes across to cover the danger. Excellent defending.
80
ARSENAL HAVE 10 MINUTES to salvage a draw to take to the Nou Camp. And you sense they will need at least that.
79
Yellow Card DIABY GOES IN THE BOOK: He stopped Keita after a misplaced pass in midfield.
77
CESC IS STILL CHARGING ABOUT: But the same can't be said of Denilson, who has a knock. Clumsy challenge from Henry that but the ref missed it.
76
Substitution AND LISTEN TO THAT CHEER! Henry replaces Ibrahimovic.
76
GREAT SAVE ALMUNIA: Messi races through and Almunia stands tall to block from a narrow angle.
75
HENRY IS ON HIS WAY: The No 14 with the very familiar face is about to come on for Barca. What a reception he will get.
74
Yellow Card YELLOW CARD: Eboue goes in the book for a tackle from behind on Puyol
73
HERE COMES CESC... but he curls it well over. What a pity. Great position that for the skipper. But Arsenal are at least back in this.
72
Yellow Card YELLOW CARD: Pique is booked for that foul on Cesc
71
SUDDENLY THE FANS BELIEVE! Arsenal push forward and Barca are rocking for a moment. And the Gunners have a free-kick on the edge of the box...
69
WALCOTT'S DONE IT! What an impact from the sub! Nasri finds Bendtner, he picks out Walcott's run and the England man slots the ball past Valdes. The keeper got a touch but couldn't keep it out.
69
GOAL! - Theo Walcott 1 : 2 GOAL!!! ARSENAL 1 BARCELONA 2
68
FIRST RUN FOR THEO: Good ball from Eboue inside the full-back but Walcott can't quite cut it back for Bendtner. Promising though.
67
TACTICS: Eboue has dropped to right back while Walcott is over on the right. Arsenal will do their best to get a goal and throw themselves a lifeline.
66
Substitution SUB: Wenger plays his last card as Walcott comes on for Sagna. So Cesc will have to see out the 90 minutes.
65
DECISIONS GOING AGAINST ARSENAL and the ref is getting a lot of stick from the fans just in front of me.
64
REMINDER: Stay online after the final whistle for our post-match show. Dan Roebuck and Martin Hayes will be taking your calls as well as your e-mails so phone the studio on 020 7607 3200 (from inside the UK) or +44 20 7607 3200 (from outside the UK).
63
HENRY IS WARMING UP: Arsenal's shell-shocked fans give him a warm ovation and he responds with a clap.
62
BARCA IN NO MOOD TO SLOW DOWN: They want this tie killed as soon as possible and will look to hit Arsenal on the counter-attack.
61
WHAT A TASK ARSENAL FACE NOW: And the home fans know it. The atmosphere has gone really flat here.
59
IT'S IBRAHIMOVIC AGAIN: The Swede is played through, stays onside, steadies himself and lashes a shot into the roof of the net. No keeper in the world would have stopped that. Is that game, set and match to Barca?
59
GOAL! - Zlatan Ibrahimovic 0 : 2 GOAL!! ARSENAL 0 BARCELONA 2
58
CLICHY WORKING SO HARD: He tracks Pedro and it's a thankless task but the Frenchman sticks at it and forces Barca away from goal. Hats off to him. Remember, Clichy is also on a yellow card.
56
UNLUCKY BENDTNER: Vermaelen's long pass finds the Dane's run but Puyol gets there first, clears against Bendtner and the ball rolls kindly for Barca's keeper Valdes.
54
WHAT A CHANCE FOR BENDTNER! Great cross from Clichy and Bendtner meets it powerfully but he heads it straight at Valdes. That should have been 1-1... now Xavi heads just wide at the other end! Another good chance for Barca. But Bendtner holds his head in his hands and rightly so.
53
...IT HITS THE WALL and Busquets fires the rebound straight at Almunia.
53
FREE-KICK TO BARCA and it's right on the edge of the box. Here comes Messi...
51
PEDRO SHOOTS WIDE... and he should have done better. Delightful play from Barca, wonderful possession football, and the ball drops to Pedro who lashes it wide from the edge of the box.
49
FABREGAS IS BROUGHT DOWN: But the ref gives nothing. Cesc and Pique chased down Arsenal's left, they both tumbled and Pique appeared to pull back his mate as he got up. The home fans are disgusted
47
ALMUNIA FROM HERO TO VILLAIN: He kept Arsenal in the tie in the first half but that was poor judgement. And Barca now have the away goal they craved.
46
DREADFUL START TO THE SECOND HALF: A lofted ball down the right catches Arsenal out, Almunia rushes out when he shouldn't have and IBRAHIMOVIC lobs the ball over him on the run. It was good technique but Almunia made it easy for him.
46
GOAL! - Zlatan Ibrahimovic 0 : 1 GOAL! ARSENAL 0 BARCELONA 1
Kick Off MESSI KICKS OFF THE SECOND HALF: And there's a man who could have had a few in the first half.
45
The teams are back out. Brace yourselves.
45
Even worse for Arsenal, they have lost Gallas and Arshavin to injury and Fabregas will miss the second leg after picking up a harsh booking.
Half Time You have to say that was an absolute masterclass from Barca, especially in the first 25 minutes. Almunia kept Arsenal in the tie and they did threaten at the other end as the half wore on. But how it is still 0-0 is a mystery to me.
Half Time HALF-TIME: Arsenal 0 Barcelona 0
45
WELL INTO STOPPAGE TIME: It's been a breathless half at the Emirates.... and Nasri almost finds Bendtner again! Good move from Arsenal.
45
CESC WILL BE GUTTED: He went down on his knees as the card was produced. Really poor decision too. Let's just hope he can see this one through.
45
Yellow Card TERRIBLE FOR CESC: His excellent sliding tackle earns a yellow card - and that means he misses the second leg at the Nou Camp
45
Substitution SUB: Gallas is replaced by Denilson with Song dropping back to centre half.
43
NASRI ALMOST PICKS OUT BENDTNER! His left-wing cross just eludes the big Dane and Barca clear.
41
GALLAS IS GOING OFF ON A STRETCHER: The gamble has back-fired and that is dreadful for Arsenal
41
Yellow Card YELLOW CARD: Song is booked for not retreating 10 yards at a free-kick. And even worse news...
40
...BUT VALDES CLAIMS EASILY. That was an anti-climax with Arsenal players lining up to meet Cesc's delivery.
39
FREE-KICK ARSENAL: Clichy is fouled by Alves...
38
BENDTNER OFFSIDE! He's 'saved' by the flag after firing straight at Valdes from six yards and hitting the post with the rebound! Gasps around the Emirates.
37
WATCH OUT: Barca have a free-kick. Messi lining it up 25 yards out... straight at Almunia. His handling has been impeccable so far.
36
DIABY HEADS WIDE: Good play from Bendtner on the right and his cross is nodded down by Diaby. That's not troubling Valdes though.
35
BARCA PASS MASTERS: I was talking before the game about Arsenal's high tempo but the speed with which Barca move the ball is incredible.
34
CLICHY FOULS ALVES: But no yellow card for the Frenchman.
33
ANOTHER BARCA CHANCE: This time Zlatan fires wide after more neat build-up. We're so used to seeing Arsenal dominate possession but it must be 60-40 to Barca so far in that department.
32
WOULD WENGER TAKE A 0-0 NOW? I reckon he would. A clean sheet would be so precious going into the second leg.
31
WELL DONE NASRI! Excellent defending to track and then tackle Pedro. More of that please, Arsenal.
29
MESSI TESTS CLICHY AGAIN: Gael left exposed against the brilliant Argentine but Clichy sticks to his job and concedes a corner... which is cleared.
27
Substitution SUB: Eboue replaces Arshavin. He must have a knock. That might not be a bad thing for this game - Eboue can give us some ballast in midfield.
26
WENGER LOSES HIS TEMPER: Not surprised. Song gives it away inside his own half. Arsenal HAVE to keep hold of the ball when they get it. Surrendering possession far too easily.
25
EBOUE IS GOING TO COME ON: Is it Cesc coming off? Who else is injured? We're about to find out.
23
NASRI CURLS ONE JUST WIDE! Great effort from the Frenchman. He let fly from the corner of the box and Valdes was beaten. Two yards wide, nothing more. This is better - much better.
22
ARSENAL HAVE WOKEN UP! Suddenly Song is in charge in midfield, Sagna crosses, it's cleared, but Arsenal have that foothold.
21
Yellow Card YELLOW CARD: Arshavin goes in the book for a tackle from behind. Bit harsh really.
21
ARSENAL CHANCE! Finally! Good pressure in the final third and Arshavin curls in a cross which is just deflected away from Cesc.
20
WENGER CROUCHED IN THE TECHNICAL AREA: There is not a lot he can do to stop this. Maybe bring on a defensive player like Eboue?
18
ANOTHER GOOD ALMUNIA SAVE... this time from Pique's header. The crowd try to lift their team. Come on Arsenal!
17
PEDRO SHOOTS... and it flicks off Sagna and goes behind for a corner. Every second ball is falling to Barca too it seems.
16
ARSENAL SHELL-SHOCKED: Even when they do get the ball, they can't keep it. They are not doing the basics and to be fair Barca aren't letting them. I know I'm repeating myself but the champions are awesome.
14
AMAZING STUFF HERE! Almunia makes two terrific saves to deny Zlatan and Xavi. Then Arsenal somehow survive after a succession of shots are blocked or headed away. Arsenal's goal leading a charmed life!
13
ANOTHER QUICKFIRE BREAK... and this time Messi shoots wastefully over the bar. Arsenal just not getting close to them.
11
SONG FOULS KEITA: That has at least slowed the game down for a moment. The crowd start to raise themselves. The key is this: we haven't conceded.
10
BARCA ON ANOTHER PLANET: Arsenal cannot stem this tide at the moment. They need a foothold in the game. Barca said they were coming to attack and they have been true to their word.
8
IBRAHIMOVIC GOES CLOSE AGAIN! Arsenal get the ball - at last - but give it away. Barca break, Zlatan outpaces the defences but finds the side-netting. It's no understatement to say this could be 3-0 to Barca already.
6
REALLY GOOD SAVE AGAIN FROM ALMUNIA: This time he blocks with his legs from Messi... and now Ibrahimovic skies one over the bar from five yards! This is too much.
4
ARSENAL CAN'T GET OUT OF THEIR HALF: It's all Barca. Xavi pulling the strings from midfield. A cross just eludes Ibrahimovic. Arsenal need to weather this storm.
2
GREAT SAVE ALMUNIA! Corner is laid back to Busquets who fires low towards goal. Almunia dives full length to push the ball away. Barca are on fire here.
1
MY WORD, THAT WAS CLOSE: Vermaelen makes a magnificently-timed clearance to deny Barca from Ibrahimovic's cross
Kick Off WE'RE UNDERWAY AT THE EMIRATES: And Diaby makes an early surge down the left
Massive reception for both teams. The glamour tie of the round is here. The Champions League music rings out and Henry looks on wistfully from the bench.
The players are in the tunnel. Arsenal in red, Barca in yellow. Come. On. You. Gunners.
We're just moments away. You know how I know? 'The Wonder Of You' is blasting away over the PA. Wonderful scenes here at the Emirates: scarves aloft, flags and banners draped here and there. Lovely stuff.
If you're not already listening to our MatchDay Show, make sure you tune in without further ado. Coming up: an exclusive interview with the boss (including his take on Cesc's fitness) and live commentary with Dan Roebuck and Martin Hayes. Get your e-mails in now via www.arsenal.com/studio.
That's a good sign: Fabregas trots off and applauds the fans as he enters the tunnel. Henry does likewise moments later to a huge ovation.
Such anticipation here. I suspect a lot of fans will sacrifice that final pint to get to the ground early and savour the atmosphere. The Emirates certainly looks fuller than usual 15 minutes before kick-off
At the other end Fabregas is being 'put through his paces'. No signs of discomfort but then I can hardly make out his facial expressions from here.
Speaking of the great man, he's limbering up about 100 yards in front of my seat in the press box. Barca are pinging the ball around dressed in their garish, illuminous yellow training tops. The kind of thing you'd wear cycling but not socially.
By the way, Thierry Henry is on the bench for Barcelona. He will be champing at the bit to get on.
Fabregas and Gallas named in the line-up but Cesc will be withdrawn if he feels any ill-effects from his leg injury during the warm-up. So fingers crossed he is OK. Four changes in total: Gallas replaces Campbell, Vermaelen replaces Denilson, Arshavin replaces Walcott and Nasri steps in for Rosicky.
Arsenal team: Almunia, Sagna, Gallas, Vermaelen, Clichy, Song, Fabregas, Diaby, Nasri, Arshavin, Bendtner. Subs: Fabianski, Rosicky, Eduardo, Walcott, Denilson, Eboue, Campbell.
The buzz in the press lounge surrounds the participation - or otherwise - of Cesc Fabregas and Thierry Henry. We'll have the team news as soon as it breaks in the next 20 minutes or so.
Whatever optimism there is, let's hope it lasts longer than last year's Semi-Final against Manchester United. Lots of noise, lots of flags, then lots of anguish.
Predictions then? A straw poll in the office today proved inconclusive. Some bullish: "3-0 Arsenal". Others resigned: "3-1 Barca". I suspect the lack of consensus is because no one really knows how good Barca will be against high-tempo English opposition. We shall see. What do you think? Let us know via www.arsenal.com/studio.
I'm Chris Harris, your text commentator for tonight, and I've never seen the Arsenal press lounge so busy. It's a bonafide media frenzy here at the Emirates.
Martin Hayes joins Dan Roebuck in the commentary box tonight and, as ever, they will be fielding your e-mails during and after the match. Get them in now via www.arsenal.com/studio. And don't forget to stay online later on for our post-match show as Martin and Dan pick the bones out of what will hopefully be a memorable night at the Emirates.
Our MatchDay Show gets underway at 7.15pm (UK time) with highlights of our last match, the key moments from Arsene Wenger's pre-match press conference, an exclusive interview with the boss and an insight into our opponents.
What, you mean there's a match on tonight? I hadn't noticed... Welcome along to Arsenal TV Online for live coverage of the most glamorous game of the season. It's Arsenal v Barcelona, it's the Champions League and it doesn't get much bigger than this.
