Arsenal controlling the game at the moment! Speed hurts teams. Chelsea can't cope with Walcott or Chamberlain.

Jason R. Vowles: A slow but inevitable comeback to top form. Arsenal to truly challenge the Premier League title this year.
Raymond: What a first half. Chamberlain with a superb goal. The Gunners just need to hang in there for another 45 mins.
Ian Dobson: Considering he's "better than Ronaldo", Eden Hazardly done a thing so far...

Loic Remy's touch map shows the Chelsea forward is getting himself into some decent positions....unfortunately he has been caught off-side four times in the opening 45 minutes.

"Eden Hazard has done very little so far for Chelsea. And the player who has really stood out for me is Arsenal's Francis Coquelin. He has been outstanding. He just keeps growing and growing as a player."

Emmanuel: Selfie team 1-0 Chelsea.
Chelsea Warrior: Rubbish first half. Sort it, Jose.

"A fantastic back end to the first half, both sides lifted it but I'd like to have seen more chances from Chelsea.
"Arsene Wenger will be delighted though. His team have played with intensity, skill and shown some brilliant touches around the box."
Arsenal 1-0 Chelsea
Jose Mourinho begins his march down the tunnel just before half-time. He stops momentarily and looks back as Arsenal attack, but it comes to nothing and the referee blows his whistle.
Advantage Arsenal at the break.
Arsenal 1-0 Chelsea
Petr Cech has had very little to do in the Arsenal goal, but is alert to catch a deflection off Per Mertesacker when Cesc Fabregas's free-kick into the area skims the head of Branislav Ivanovic and hits the defender.

"What a clearance that is from Branislav Ivanovic. He just does not give up! Brilliant play from Alex Oxlade-Chamberlain to set the chance up but how brave was that from Ivanovic, with Nacho Monreal ready to nod in at the far post."
Arsenal 1-0 Chelsea
They've had some defending to do, but Arsenal attack and almost grab a second as Alex Oxlade-Chamberlain crosses for Nacho Monreal, who heads over under pressure from Branislav Ivanovic.

Ox's goal reminds me of a goal his dad Mark scored for Pompey many years ago against Plymouth at Home Park. Beat two, cut inside on his left foot and then bent it round the 'keeper. Both great strikes.

Josh Hammond: If Raheem Sterling is worth £49m I wonder how much Oxlade-Chamberlain is worth... miles better than Sterling in my opinion.

"Ramires has got to do better with that chance. It's a fantastic ball in by Loic Remy and Ramires is on his own, he's unmarked. All he has to do is head the ball down to put it away."
Arsenal 1-0 Chelsea
BBC Sport's Danny Murphy: "I was no Bob Latchford but I think I would have scored that. That was Chelsea's best chance yet."
Arsenal 1-0 Chelsea
Risky stuff from Per Mertesacker, who tries to play Loic Remy offside. He fails and is left scrabbling to try and recover as Remy escapes on the left. The striker crosses for Ramires, who rises to meet the ball and has to score, but somehow heads just over.

"Cesc Fabregas is now playing alongside Nemanja Matic. He was having no effect at all in the number 10 role and Willian is there now. I'd say that's the Brazilian's best position. Jose Mourinho made the change straight after the goal, and Chelsea are already looking better."
Arsenal 1-0 Chelsea
Next, Ramires has a pop from distance. Not far off.
Pretty entertaining stuff so far at Wembley, the two teams are certainly not going through the motions anyway.
