IT'S ALL OVER HERE AT THE EMIRATES: Arsenal have come from behind to beat the mighty Barcelona thanks to late goals from Van Persie and Arshavin
Full Time THAT'S IT! ARSENAL 2 BARCELONA 1!
90
CLICHY HACKS IT AWAY: Barca are probing for an equaliser with Messi pulling the strings. Szczesny comes out to meet Alves, the right back still finds Messi but his shot is blocked!
90
SECONDS REMAINING NOW: Can Arsenal hold on for a famous win?
90
WE'RE INTO STOPPAGE TIME: And we have two minutes to be added on. Arshavin breaks down the left but to no avail
89
Substitution SUB FOR BARCA: Adriano replaces Iniesta
89
WELL DONE SZCZESNY: He bravely dives at the feet of Messi just after making a save from Alves. Good keeping but Barca showed there they are still a real threat
88
CLICHY LOOKS FOR FABREGAS... but that is beyond him and floats out of play.
87
BENDTNER DOES WELL: Nicklas breaks into the box and gets past Alves. He wins the corner though. Arshavin to take it... Barca get it half away
86
Yellow Card YELLOW CARD FOR VAN PERSIE: Robin goes in the book for a foul
85
WHAT A TURNAROUND! The home fans are out of their seats. Scarves are held aloft, flags flutter and Barca, for once, are stunned.
83
MARVELLOUS FINISH FROM THE SUB: Nasri got free down the right, he cuts inside and sets it up for Arshavin to apply a cool first-time finish!
83
GOAL! - Andrey Arshavin 2 : 1 ARSHAVIN FIRES ARSENAL AHEAD!!! WHAT A GOAL!!!
82
A VITAL TEN MINUTES NOW: If Arsenal can find another goal they have a real chance in the Nou Camp.
81
ARSENAL BUILD FROM THE BACK: They have a spring in their step now. Cesc tries to sneak it through for Wilshere but that's intercepted
80
COME ON ARSENAL! The home fans raise the volume as Eboue races down the right. Can they find a winner?
78
HOW DID HE SCORE FROM THERE?! Clichy clips it over a defender into Van Persie's path and the Dutchman leathers it past Valdes at his near post. Audacious!
78
GOAL! - Robin van Persie 1 : 1 WHAT A GOAL FROM VAN PERSIE! THAT'S THE EQUALISER!
78
ARSHAVIN WITH THE CORNER... and Valdes claims that comfortably. Disappointing.
77
BARCA WON'T BE UNHAPPY: Theo has given them plenty of problems and Arsenal now lack pace in behind. Hang on... Wilshere into the box and he wins a corner.
77
Substitution ARSENAL SUB: Bendtner comes on for Walcott
76
A HUGE CHEER GOES UP... as the linesman down in front of me gives an offside against Barca. He's not popular but I can't see what he's done wrong
75
BENDTNER IS GETTING READY: Who will come off? Maybe Nasri? He's only just back from injury after all
74
BARCA SEEM HAPPY WITH THIS: Keita for Villa was a defensive move by Guardiola but Arsenal need the wit to open up the visitors. Will they get the chance they crave?
72
OUCH! Messi catches Koscielny in the stomach with a high challenge, he was going for the ball. No card for the Barca wizard
72
MARTIN HAYES: 'They are doubling up on Theo Walcott.' Have your say at www.arsenal.com/studio
71
WALCOTT GOES DOWN THE RIGHT: He tries to win a corner but gets the last touch. Goal kick to Barca. Theo has not had so much joy since his sparking start to the game
71
ARSENAL RUNNING OUT OF TIME: Less than 20 minutes to go. Meanwhile Pep Guardiola is incensed after Arsenal get a throw which looks to be Barca's.
70
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).
69
TACTICS: Nasri tucks in alongside Wilshere. Song did look tired to be fair
68
Substitution ARSENAL SUB: Arshavin comes on, Song comes off.
68
Substitution SUB FOR BARCA: Villa comes off, Keita comes on
67
MESSI MUST SCORE! But no! Iniesta's pass picks out the Argentine but he can only find the side-netting
66
VAN PERSIE CURLS ONE: But that's easy for Valdes. Robin hasn't really got behind one yet.
65
CORNER TO BARCA: And Arsenal are incensed. It looked like Villa got the last touch. Either way Arsenal clear
65
KEITA IS COMING ON: He's got his tracksuit top off
64
ABIDAL TAKES A TUMBLE: Eboue is penalised and Barca have a free kick. They take it short and back it goes to Pique
63
NEXT GOAL SO VITAL: If Barca get it life will become extremely tough for Arsenal. But the home side are threatening more in the second half
61
NASRI WITH THE LOW CROSS... and that is cleared away for a corner. Barca clear and break but Clichy gets in well.
59
Yellow Card YELLOW CARD: Pique goes in the book and he will miss the second leg now. Free kick to Arsenal but that's easy for Valdes
58
CORNER TO ARSENAL: Nasri wins it and takes it. The ball falls to RVP but he opts not to shoot first time, Wilshere can't get a shot away and Barca clear
57
PENALTY SHOUT! Pedro goes through, he looks offside but the flag stays down, Koscielny covers, Pedro tumbles, big shout… not given!
55
CESC STOPS BUSQUETS: And Arsenal can counter with Walcott. He gets two tries with crosses and eventually Van Persie gets a shot away but his radar is off tonight
54
WALCOTT AND CESC NOT ON THE SAME WAVELENGTH: Theo thinks his skipper has gone outside, but he's made a different run. The pass goes astray, the crowd groan
53
XAVI ON THE VOLLEY! Cross from the left and Xavi hits it first time... but that is wide. Now the crowd are up in arms after Clichy is penalised for a foul on Alves
52
POOR FROM SONG: Arsenal get into a good position on the edge of the box but Song tries too much and gives the ball away.
51
BARCA BACK IN THEIR STRIDE: Messi goes down the right and almost leaves Koscielny for dead. Arsenal get it back though, they look more dangerous since the break
50
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).
49
ARSENAL SUBS WARMING UP: Bendtner and Denilson are going through some stretches down in front of me. Arshavin is there as well
48
VALDES SAVES FROM WILSHERE: Easy for the Barca keeper but Arsenal worked that well and Jack shot from just inside the area
47
FABREGAS TRIES HIS LUCK: But that hits a defender. Proactive stuff though and that's good to see
46
VAN PERSIE GOES THROUGH... but he's flagged offside. Good start from the Gunners
Kick Off WE'RE BACK UNDERWAY: Arsenal attacking the North Bank in this second half
45
David Villa fired Barca ahead, Song is skating on thin ice after an early yellow card and Arsenal have a lot of work to do to take a first-leg advantage to the Nou Camp
45
That's your lot for the first half. Arsenal have worked their socks off but they are struggling to play their normal slick football against this outstanding Barca side
Half Time HALF-TIME: ARSENAL 0 BARCELONA 1
44
MARTIN HAYES: 'We need to calm down around the box and show more quality' Have your say at www.arsenal.com/studio
42
LABOURED: Arsenal usually pass teams off the pitch but they are resorting to longer, more hopeful balls. It's not working so far.
41
VAN PERSIE LOSES OUT: He collects the ball 40 yards from goal and makes a beeline for the area but gets tackled easily. Arsenal just not playing their usual game, Barca have knocked them out of their stride
40
THE FIRST HALF HAS FLOWN BY: Five minutes plus stoppages remain. Song does well on the right but Arsenal can't keep it for long enough
39
KOSCIELNY RESCUES DJOUROU: Poor pass from Johan but Koscielny comes across to stop Pedro. Phew.
38
MESSI IS OFFSIDE! The Argentine gets the ball in the net after an exchange with Pedro but the linesman saves Arsenal. Once again Barca played through the home side's defence with relative ease
36
EBOUE SURGES FORWARD: But he is brought down about 25 yards out. The ref gives nothing and he's probably right
35
FABREGAS SHOOTS! But it hits Van Persie. Typical. Good effort following Walcott's surge but Arsenal's luck is not in right now
34
ARSENAL'S PASSES MUCH LONGER: While Barca pop it about five yards to a team-mate, Arsenal's passes are about 15 yards. That's because they are not as in tune with each other as the visitors
32
CALM DOWN! That's the message from Cesc to his team-mates as another one goes charging into a tackle. They cannot get a touch at the moment
32
ARSENAL LOOKING FOR THE BREAK: The home side are being forced to play like an away side because Barca are so good on the ball. It's a joy to watch in many ways but painful for Arsenal
31
MARTIN HAYES: 'Sooner or later the ref is going to send Song off'. He's right, Alex is committing foul after foul.
30
ANOTHER CHANCE FOR RVP: And it's a really decent one. Wilshere breaks, he picks out Robin and the in-form Dutchman skews horribly wide. Big, big miss
29
Yellow Card YELLOW CARD: Iniesta goes in the book
29
ALVES ALMOST SETS UP VILLA: Arsenal just smuggle it away but they are diving in to try and stop Barca. It's desperate defending at the moment
28
Yellow Card YELLOW CARD FOR NASRI: The Frenchman goes in the book for a foul on the left flank. Frustration setting in.
26
MESSI SET IT UP: The Argentine slides it through for Villa to race through and he finds the bottom corner. Simple goal and Arsenal were cut apart, just moments after they could have taken the lead
26
GOAL! - David Villa 0 : 1 GOAL! VILLA FIRES BARCA IN FRONT!
25
ARSENAL SO CLOSE! Brilliant run from Walcott, he finds Cesc, he crosses and Abidal nicks it away from Van Persie as he looks to finish it off with his head! Wonderful break from the Gunners!
24
SONG GETS A FINAL WARNING: The ref thinks he raised his arm there but it looked like a fair challenge. Arsenal can ill-afford to go down to ten men against this lot
23
SILLY FROM ARSENAL: No one gives Eboue an option from the throw, he tries to find Wilshere, he is dispossessed and Messi can't quite chip Szczesny. Arsenal giving it away far too cheaply
22
BIG CHEER FOR THEO: He works back well and challenges Maxwell - fairly. Arsenal fans scream for a corner as the home side go forward but the linesman (just yards away) doesn't give it
21
MARTIN HAYES: 'Barca are so comfortable on the ball. Arsenal are taking a risk by holding a high line' Have your say at www.arsenal.com/studio
20
SO CLEVER: Barca's interplay almost carves out a chance. Messi's cheeky chip so nearly finds Villa inside the box
19
SZCZESNY RUSHES OUT: He claims well as Villa tries to latch onto a through-ball. Arsenal break and Van Persie can't win a corner. The visitors on top still
18
WALCOTT DEFENDS: He covers back to help Eboue and gets a vital interception in. Then he gives it away but Arsenal escape
16
BARCA ON TOP: The visitors are popping the ball about with their usual panache. Their movement is something to behold.
15
HE IS HUMAN AFTER ALL! Messi charges onto Villa's through-ball and is in on goal... Szczesny comes out and stands up as long as possible... Messi clips the ball over him and just past the post! What a chance
13
VILLA CLOSING DOWN: The Barca striker is giving Djourou and company very little time on the ball, forcing them to hurry their distribution from the back
12
OOOH. CESC JUST FAILS TO FIND RVP: Clichy made good headway down the left flank and found his captain in space. He went for the first-time pass but messed it up
10
INIESTA LOOKING DANGEROUS: He tries to find a way through the centre of the Arsenal defence. That yellow card to Song is frustrating - he can't afford a mistimed tackle now
9
IT'S COMPELLING STUFF: Both sides have started well and Arsenal look aggrieved there, they felt there was a Barca handball just outside the box. Chest, indicates the ref
7
Yellow Card YELLOW CARD TO SONG: He goes in the book for a foul on Messi. The crowd roars its disapproval
6
GREAT SAVE VALDES! Wonderful play from Arsenal! Walcott causes havoc with a jink inside the box, he finds Fabregas and he lifts it over the top to Van Persie. Valdes makes the save but Arsenal look good here
5
THERE GOES THEO: You can see why Barca are scared of him. He surges a good 40 yards, no one can catch him, but the pass to Van Persie is just overhit
4
FREE KICK TO ARSENAL: In a good position. Xavi penalised, Cesc will swing it in... and it goes all the way through to Valdes, via a feint touch from Djourou I think
3
EARLY TOUCH FOR SZCZESNY: He takes a goal kick after that Barca move finally broke down. Nerves? Even he might be feeling some tonight
2
HARD WORK OFF THE BALL: That's the key for Arsenal here. They are putting in the graft but it's very hard to get near Barca.
2
EARLY POSSESSION FOR BARCA: They work the ball left to right, right to left, and Arsenal snap at their heels
Kick Off AND OFF WE GO! Barca get us underway at the Emirates
The place is packed now. The home fans shout the names of their team back at the stadium announcer. Cesc gets special treatment, of course. The players go through some final stretches while Cesc and Xavi greet each other and toss the coin
A flurry of flags and beams of light greet the teams. Emirates Stadium has never looked so fine. And we are just moments away from kick off.
Here they come... Arsenal in red, Barca in their change strip of green.
Fabregas and Xavi stand in front of their teams in the tunnel. Both utterly focused. They won the World Cup together last July, now they go head to head...
This is what it's all about. Can Arsenal upset the 'best team in the world'? We're about to find out.
An almighty roar goes up as Elvis finishes. Expect a crackling atmosphere tonight. Eight minutes to the off and hoards of snappers are poised at pitchside to capture the players as they emerge from the tunnel
Flags are fluttering here at the Emirates as 'The Wonder Of You' rings out. It's a glorious sight...
Quick disciplinary fact for you: Eboue is the only Arsenal starter one booking from a suspension. Of course he's playing because another right back - Sagna - is banned
What do you reckon Arsenal fans? Get your comments in via the website at www.arsenal.com/studio. Dan and Martin will be fielding your e-mails during and after the match
A Spanish announcer is reading out the Barca team. Each name is greeted with a hearty roar from the away end.
Still plenty of empty spaces here but they will fill up fast. Van Persie is the last Arsenal player back down the tunnel - time for those final preparations
Just down in front of me is probably about half a billion pounds worth of talent. And none better than Lionel Messi. He's warming up with Mascherano and Maxwell as, gradually, the Barca players troop off down the tunnel
Twenty minutes to kick off then folks. If you can't get up for this one, you might as well give football a miss. Emirates is about to play host to a meeting of minds, a head-to-head between arguably the two most aesthetically-pleasing sides on the planet
Speaking of which, the show is about to start. If you're not logged in, hurry up! Lead commentator Dan Roebuck is just to my right - he'll be taking you through the teams and setting the scene in just a moment
All around me are red seats and each one has a special flag tucked into it. That should make for a splendid sight when the teams emerge from the tunnel. What's more, we are expecting a light show before kick-off. Look out for it during our MatchDay Show
...to my right, the Barcelona fans are in good voice. The away section is almost full already but only a few Barca players are limbering up at the moment
I'm up in the press box at the Emirates so let me paint a picture for you. To my left, the Arsenal players have just emerged from the tunnel in their blue tracksuit tops. Nasri is there among them...
That's a significant improvement on last season's first leg when Arsenal risked Gallas and Fabregas - and lost them both by the end of the game. Arshavin also limped off in that match while Van Persie was a notable absentee. Not tonight
Nasri returns to the Arsenal side for the first time since straining his hamstring in the FA Cup on January 30. Which means Wenger can field arguably his strongest side, with the notable exception of the injured Vermaelen.
And the subs: Almunia, Rosicky, Denilson, Squillaci, Arshavin, Gibbs, Bendtner
Arsenal team: Szczesny, Eboue, Koscielny, Djourou, Clichy, Song, Wilshere, Fabregas, Nasri, Van Persie, Walcott - SO SAMIR NASRI STARTS!

Anyone who saw that Quarter-Final first leg was treated to a Barca masterclass. Wenger admitted his team were 'spectators' for much of that 2-2 draw - tonight we'll find out if they've learned their lesson.
So here we are for the ultimate test of Arsenal's credentials. A chance to measure their improvement against the best in the business and a team that dismantled them in the first half-hour of last season's meeting at the Emirates
I'm Chris Harris, your text commentator for the night, and I'll have the teams for you in just a moment.
Former Gunner Martin Hayes is alongside Dan Roebuck in the commentary box and they'll be taking your e-mails while they call the shots. Get in touch via the website at www.arsenal.com/studio
Our coverage starts at 7.15pm (UK time) with highlights of the weekend win over Wolves, the best bits from Arsene Wenger's pre-match press conference and, of course, all the breaking news from Emirates Stadium
Excited? You bet. Welcome to Arsenal TV Online for live coverage of a game that screams 'glamour'. It's Arsenal v Barcelona, it's the Champions League and it's all coming your way in the MatchDay Show
