Good afternoon, and welcome to our LIVE coverage of Arsenal v Manchester United. Team news is just in...

GOAL! Valencia fires a ball across goal. Comes off the boot of Gibbs before spinning into the net. United have the lead. An own goal.

Arsenal are unbeaten in their last 23 Premier League matches at home, since losing 3-1 to Aston Villa on 17 August 2013. It is their best streak since April 2007 – August 2008 (25 matches).

Wilshere's match is over. He is going off to be replaced by Santi Cazorla. A standing ovation for Wilshere as he departed.

Wilshere limping off to the side of the park. Not sure how much more of this match he is going to see.

McNair slides in on the side of Wilshere. He looks to be in a spot of bother here after Fellaini had given the ball away.

Superb pace shown by Welbeck to race into the United box, but terrific stop by De Gea to ensure the ball doesn't end up in the net.

Mertesacker lifts the volley over the bar under pressure from Fellaini. Some more frantic defending by United.

Oxlade-Chamberlain with the run and cross, but walloped clear by Fellaini. Arsenal starting the second half well.

There goes the whistle for the break! It is 0-0 at half-time. Arsenal should probably be ahead, but they could also be down to 10 men with Wilshere sticking his head in Fellaini's frame.

We are into two minutes of time added on.

Chambers hesitates over a potential cross. Ball spins off the outside of his boot before dropping out of play. Goalkick to the visiting side.

Blackett doing well to come across the park to hammer the loose ball away from Oxlade-Chamberlain. Arsenal will be happier at the break.

Sanchez continues to work so, so hard. Tracking back whenever he can. The man is a real thorn in the side of any opponents.

De Gea fails to deal too well with a corner. Ramsey sets up Welbeck, but his backheel is wide of the target. We remain at 0-0.

Golden chance for Smalling in the Arsenal box, but he fails to connect after the ball came off the back of Welbeck's head. Ball spins wide. What a chance that was for the opening goal.

United finally settling into this game. Getting on the front foot after a survival plan for the past 25 minutes.

Arsenal have lost to Manchester United 20 times in the Premier League, more than they have against any other team.
