1'
Here we go, Man United kick us off. Hold on tight!
1'
United are shooting from left to right. Arsenal, in their yellow and burgundy away kit, shooting to the left.
2'
Sagna plays a nervy backpass to Szczesny, which he clears. Not what the young goalkeeper needs on the biggest night of his life.
3'
Szczesny, 20, is half the age of his opposite number, Edwin Van der Sar. When was the last time that happened? Answers on a postcard.
3'
An even start to this one so far, neither side developing into their rhythm yet.
4'
Arshavin makes a strong darting run down the left and finds Song, who is tackled on the edge of the box by Park before he can get his shot away.
5'
Clichy gets caught out of position and is all over the back of Nani and eventually concedes the free kick. Poor by Clichy, who gets a ticking off by the referee.
5'
United, incidentally, wasted the resulting free kick and Arsenal clear their lines.
6'
Arsenal looking dangerous on the break. Rosicky finds Sagna on the right wing, but his cross from the right is too deep for Chamakh and Rafael gets it away after almost giving away a careless corner.
7'
United launch an attack in very direct fashion. Van der Sar punts it downfield to Rooney, who turns Koscielny and Squillaci before unleashing a good effort from 25 yards. But Szczesny gets down well to save. Exciting start to this one.
8'
Rooney is looking sharp. He must be if he's relegated Berbatov to the bench.
9'
Chamakh stoops to get his head on a cross from the right but he can't trouble Van der Sar with the header.
10'
David Beckham is in the crowd for this one. He looks cold.
11'
Howard Webb is having to deal with some rough tackles at the moment. He's awarded a free kick against Song some 35 yards out. Nani to take...
12'
Nani cleared the wall but his dipping free kick was gathered easily by Szczesny.
13'
 Rosicky dives in recklessly on Ferdinand and is correctly cautioned by Mr Webb.
14'
Wilshire runs into some space and tries a one-two with Rosicky, but the Czech's ball is just behind Wilshere and the chance is gone.
15'
Wilshere slips in his own half and Park takes advantage and runs at Sagna. But the Korean captain delays his cross and Song gets across and deals with the danger. Park a little too ponderous there as Rooney lurked in space in the box.
16'
Carrick wins the ball from Wilshere again and launches a United attack. Nani plays it back to Carrick, who finds Anderson in a dangerous position, but Anderson is offside.
17'
Stat: Rio Ferdinand last conceded a foul in the Premier League on April 11 2010 vs Blackburn, 246 days ago.
18'
The players seem to be having trouble with the Old Trafford surface tonight. Wilshere, Evra and Nasri have all slipped over already!
19'
Szczesny claims an overhit Park through ball. Szczesny doing well so far.
20'
Great chance for United, The best of the game so far! Fletcher's cross for Rooney is headed out by Koscielny but only as far as Nani who volleys it first time towards to the far bottom corner, narrowly missing the post.
21'
Penalty claim for Arsenal! Rafael appears to drag Chamakh down in the box as Nasri's cross is cleared. Penalty? It is for me.
23'
United are beginning to dominate the game here. Triangular passing going nowhere in particular, but making Arsenal work.
25'
Squillaci floats a free kick forward which Chamakh flicks on unchallenged, but it goes beyond Rosicky.
26'
Arsenal have the first corner of the game...
27'
But United clear and get the ball up to the lone striker, Rooney. But Arsenal are on to Rooney like a disease and deny him any time to craft a chance.
28'
Another dodgy backpass by Sagna! Szczesny again has to sprint out to save Arsenal's blushes.
29'
Sagna gets his foot in to stop Anderson from advancing into the box, but at the expense of a corner...
30'
Penalty claim for United! The ball is played short to Nani, who whips a low cross in from the right which definitely strikes Chamakh's hand, albeit accidentally.
31'
Chamakh has been at the centre of penalty claims at bothe ends now.
32'
At least Chamakh is at the centre of the action. Nasri has been largely anonymous so far.
33'
Stat: The last Arsenal keeper to make his league debut v Man Utd was Stuart Taylor in 3-1 win at Highbury in Nov 2001.
34'
Song tangles with Park.
35'
Rooney takes a petulant little swipe at Clichy after losing the ball to the Frenchman. Some things never change.
36'
Chamakh comes deep to claim the ball, Vidic follows him halfway into the Arsenal half and fouls him. That's been the story of the game so far, I'm afraid. The first 36 minutes have not been the most memorable.
37'
Webb is having to deal with some handbags here. Fletcher feels he was blocked by Song, who has employed the puppy eyes. Song has got away with that, Fletcher is livid. Sir Alex is out of his technical area.
39'
 GOAL 1-0 Man United!
40'
Park gives United the lead with a superb header! Nani does well to cut inside Clichy on the right, crosses for Park with his left foot and twists his body to improvise a header over Szczesny.
42'
 Chamakh has caught Nani and goes into the book. Definitely late, definitely a yellow.
43'
Fletcher and Wilshere squared up after that challenge and Webb had to part them.
44'
Fletcher had a sniff of goal there but Song did well to slide in and divert the ball back to Szczesny.
45'
 Arshavin is booked for an awful two-footed lunge on Fletcher. Clearly a yellow.
45'
This game has been nothing more than succession of bad fouls, mostly by Arsenal. (Although Fletcher has been stirring it up)
45'
With that, we have the half time whistle. Manchester United lead Arsenal 1-0 at half time.
45'
Neither side have been anywhere near their best so far, with each looking more concerned with preventing the other from scoring (by any means necessary) than scoring themselves.
45'
Let's hope for better in the second period.
