45'
What can Arsenal do in the second half? There are very few options on their bench, with Rosicky the only experienced option for them with attacking ability.
45'
Arsene Wenger will be frustrated with his team. On the balance of play they probably deserve to be level, but they switched off and Chelsea punished them.
45'
HALF TIME Chelsea don't have time to take their corner, but they do lead at the break thanks to Didier Drogba's strike.
45'
Another corner for Chelsea, Clichy sliding in on Malouda...
45'

45'
TWO MINUTES ADDED TIME

Abou Diaby is down and looks in agony after a coming together with Michael Essien. There didn't look to be any intent to harm Diaby from Essien.

35'
Chelsea looking for penalty as Malouda's header hits Koscielny. Not a chance as it hit him in the stomach.
34'
Another wasted corner from Chelsea. Teams just don't seem to value corners anymore...
33'
Best chance so far from Drogba, who gets the better of a flailing Clichy, he fires a low shot at goal and Fabianski did well to turn it over the bar.
32'
Clichy does excellently, getting his head on Malouda's cross and then stopping Drogba in his tracks.
31'
Arsenal are beginning to look more and more threatening, Samir Nasri tucks in from the right and his bouncing effort skips just wide of the post.
30'
Didier Drogba has been quiet so far. Given his history against Arsenal and his poor performance last week he'll want to put on a strong showing today.

28'
The set pieces have wasted so far, Arsenal doing nothing with their corner.

A fantastic effort from Arshavin, taking a touch to compose himself before firing a 25 yarder at Cech's goal. The Chelsea stopper makes a fine one-handed save to give the Gunners a corner.

21'
He does better this time, being alert to gather a through pass as Anelka loomed large.
20'
Fabianski almost makes a text-book Arsenal goalkeeping error. Ashley goal puts the ball across, and under pressure from Anelka the Pole fumbles, luckily straight to Gael Clichy.
20'
The delivery is easy for Cech to collect.
19'
Neat passing, as you'd expect from Arsenal. Abou Diaby tees up Nasri for an effort which results in an Arsenal corner.
