Frankly ridiculous scenes now as Wenger is left standing amongst the United fans for the final few seconds - suffice to say they are enjoying it.

Arsene Wenger is not at all happy but he cannot complain because Gallas was clearly a yard offside - and he has been sent to the stands.

Drama! Drama! Drama! Van Persie has the ball in the net but the offside flag is up after William Gallas had strayed into an offside position.

It should have been over completely there! United break with Berbatov and Rooney creates space for Nani to go into but he fails to convert from 12 yards.

It's a frantic finish at the Theatre of Dreams but it looks like Arsenal could be done for now as they struggle to get through once more.

Arsenal aaplying even more pressure with Van Persie turning to shoot but it is blocked by Vidic and United can counter with Nani, who picks out Berbatov but the ball bobbles on him as he goes to shoot.

There will be five minutes of added time at Old Trafford. Will there be another goal? And, which way will it go?

Wayne Rooney has just made a sliding tackle with his head - and that is not a mistype. Quite amazing, and he won the ball.

Arsenal are pushing and pushing now, desperate to take something from this game and they would probably deserve something after a good display.

It's end to end stuff now as Arsenal go in desperate search of the equaliser but when they lose it United are quick to break.

Darren Fletcher has been superb once more in the heart of that United midfield - Arsenal must hate the sight of him given the way he usually plays against them.

Arsenal are turning up the hear a bit now as they try to really up the tempo and throw more bodies forward.

If Arsenal do not get something out of this game then they will no doubt feel hard done by after the effort they have made, particularly in the first period.

Nani looks like a completely different player to last season - he has pace, hunger, skill and energy, all of which were missing last term and now he harries Sagna into giving away a throw.

Brillaint from Nani! With Gallas flying in from the side the Portuguese produces a delightful flick over his body and it creates an opening for Evra whose shot is well saved by Almunia.

Wes Brown has, at times, looked like a player who has barely played in the last year and a half and this time a misjudgement almost gives Van Persie a glorious chance.

It was quiet earlier on, but now the atmosphere is much better as Old Trafford begins to rock after that two goal blitz.

Almost immediate redemption! Diaby turns Vidic superbly but when faced with the white of Foster's eyes he scuffs wide.

He really is in the mood now as Rooney turns on the halfway line and tries to smash it over Almunia's head but the Spanish keeper is alive to it to catch.

PENALTY! Giggs with a delightful ball behind the back four for Rooney who is felled by Almunia and referee Dean points to the spot.

Things are just not clicking for United in the same way that they are clicking for Arsenal in the attacking third and the frustration is beginning to show.

Another corner and another problem for Arsenal as Brown gets a near post flick on and the ball eventually falls for Carrick on the edge of the box but Eboue sticks out a leg to flick it wide.

Carrick bides his time looking for a pass and he finds Valencia with time to turn on the edge of the box but his effort is too high, but that was better movement from the hosts.

United look all over the place at the back without Rio Ferdinand today and Arsenal nearly capitalise as Eboue waits unmarked at the far post for Clichy's cross but can't bring it down.

What a save! Arshavin takes on O'Shea and Vidic to get to the byline and cross for Van Persie who pokes goalwards but Foster reacts instinctively to turn it away from goal.

The atmosphere is a little flat today at Old Trafford as the fans look for inspiration from their team - but perhaps the home side need something from them.

Sir Alex Ferguson says his summer spending is over but that news might worry United fans as their side seem to be lacking a real creative spark now Ronaldo is gone.

That was a bit of a flurry of activity from United and Arsenal seem to have weathered that storm for now.

Chance for Vidic! Giggs' corner drops to Vidic who outmuscles Vermaelen but can't direct his shot past Almunia as Arsenal scramble it clear once more.

Clever from Nani with a quick free-kick that Fletcher almost gets to but Almunia gets there sharply to divert it behind.

United seem to be missing something in the final third with Rooney not involved enough in the build up play - there might be a strike partner after the break I feel.

Mistake from Clichy lets Valencia in but he only has Rooney for support, until Giggs arrives but the Welshman's control lets him down once more.

Manuel Almunia is having a pretty easy afternoon so far - but he has the imperious William Gallas to thank for that as the Frenchman is having a fine game.

The crowd are happy! Bacary Sagna commits a cardinal footballing sin as he performs a foul throw and gets a big cheer.

Ryan Giggs with another chance to make a quick break for United with only Rooney and Gallas with him in the Arsenal half but he fails to control the ball and Sagna can get back to disposses him.

Rooney with the free-kick but it floats harmlessly wide of the goal and Almunia is able to just watch it.

Evra burts from the back to storm towards the edge of the area and Gallas has to bring him down before his international team-mate can get a shot off.

Chance wasted! Giggs this time does get possession in a meaningful area after Fletcher hassles Diaby out of position but he picks the wrong ball as Rooney and Fletcher burst into the box and Arsenal clear.

Rooney is starting to look a little isolated at times now as Nani and Valencia hug their touchlines while Giggs struggles to really get involved.

Even closer! It's coming to life now as Foster flaps at the corner and Arshavin very deliberately places towards the top corner and only misses by a lick of paint.

On the break though come Arsenal and Van Persie finds himself with plenty of space to face up Vidic and beat him but Evra stands in the way to deflect the shot over.

Almost! Evra does brilliantly to somehow keep the ball in play and whip a dangerous cross to the near post where Rooney is just inches away from poking home.

Arsenal try something off the cuff with a short free-kick but as Gallas peels away to collect a through ball Nani slots back to cut off the danger.

Rooney, who looks like he could do with a shave, is less than impressed as Valencia is penalised for sliding through the back of Clichy.

Manchester United starting to find some rhythm with Giggs at the heart of it but twice the final touch is just stray as Rooney looks to get in behind.

Arsenal work the ball in trademark style down the right flank and manage to win a corner but Foster again comes out smartly to claim.

Rooney looks in the mood this afternoon as he now tries to latch onto a looped ball from O'Shea but Gallas is across well to snuff out the danger.

Brilliant from Rooney! The ball is scrambling on the edge of the box until Rooney clips a lovely ball towards Fletcher who has escaped but can't keep his volley down.

Vermaelen is down after a blow to the head after a stray arm from Valencia catches him in the face but referee Dean deals with the incident very sensibly.

Arshavin drifts a free-kick towards the far post where Foster comes to claim but he can only palm down this time, however no Arsenal players are there and the England keeper can claim at the second attempt.

United are not passing the ball well between themselves in the midfield and at the moment Arsenal are making all the running.

Arsenal have settled the quicker of the two sides and Eboue hits the first shot of the evening but he drags it wide of the left post.

As usual with games between Manchester United and Arsenal the game begins at a frantic pace.
