Welcome to LIVE coverage of the Premier League match between Manchester United and Arsenal at Old Trafford. We'll have teams imminently.

Arsenal simply haven't been able to give their forward players any proper support today. I think we'll see a change at the break.

Van Persie kicks his heels in frustration as an attempted through ball passes him by. His movement has been superb again today.

An unmarked Giroud meets the corner with a wild header over the bar, but the whistle goes for a foul in the box anyway.

The free-kick is met by a firm defensive header but Arsenal still have it, and Giroud wins a corner wide on the left.

Cleverley trips Cazorla as the Spaniard nips the ball past him. Clumsy challenge, yellow card and a chance for Arteta to deliver this into the box.

Tom Adams tweets: "We all dream of a team of Mertesackers." If by 'we all' he means 'Tony Pulis' he might be onto something.

Wilshere is down and has his right boot off after a challenge by Carrick. We're always going to be nervous when this happens, but it seems he's OK. And Carrick escapes without a booking.

Cleverley bursts into space down the United right and tries to cross towards one of two red shirts at the edge of the box, but it is cut out by the first man. Disappointing delivery from the England midfielder.

United work the ball smartly from right to left before Evra releases Young... but the winger has strayed offside.

Defending by Santos! He nicks the ball from Rafael and passes it clear before reacting like it ain't a thang. Oh, it's a thang alright.

Here's Santos in attack now... he crosses from the left and De Gea catches. Incidentally, how is Santos scoring virtually the same as Sagna on out matchcast ratings?!

Yellow card to Ashley Young for holding back Bacary Sagna.

Twitter wag time - @MatchOfTheDave says: "André Santos being murdered. Apart from everyone, who would've predicted that?" Well, quite.

Valencia mugs Santos yet again and clips the ball in... the ball falls to Rooney on the left side whose powerful left-foot shot is parried by Mannone and the rebound falls to safety for Arsenal.

Rooney crosses deep from the right and Sagna is there to head the ball away. That fatal Vermaelen slip aside, Arsenal have defended well.

Valencia nutmegs Santos, who blocks off the winger and concedes a free-kick. He's having a tough time, is Santos.

A stoppage here while Ashley Young receives treatment. I must confess I didn't see it, but he would appear to have got a bash in the face. He'll be fine, though.

De Gea called into action as Ramsey fires a low cross in from the right. The goalkeeper parries it clear - might have been harder if an Arsenal player had made a run into the six-yard box.

The corner comes to nothing, and that allows Arsenal a little breather as we reach the halfway point of the first half.

Arsenal on the ropes here as Sagna blocks an Evra cross and the ball goes behind for a corner. Valencia is destroying Santos on the other flank.

Van Persie brings a save from Mannone after a brilliant through ball from Rooney! Another right-foot shot, not an easy chance.
