Arsenal got a fantastic early chance when Sagna whipped in a ball from the right hand side towards Chamakh but could only direct his header just wide of the post. Alex just managing to get a foot to it afterwards. From the resulting corner Koscielny headed over from 2 yards!
Nasri also got a great opportunity just inside the box but fired his shot wide.
Chelsea got their first chance of the game when Drogba raced into the box but Fabianski got down well and kept the effort out.
Minutes later Chelsea made it 1-0 after a ball was slotted through to Cole on the left hand side who fired in a low cross to the feet of Drogba who backheeled his shot off the post and in to continue his run of form against Arsenal.
The score at half time was 1-0.
A couple of minutes into the second half Arsenal had an appeal for a penalty when Ramires brought down Chamakh but the referee was perfectly placed and waved the play on.
It was all Arsenal and Nasri was set free by Song but his low cross was begging for a finish but did not get one.
Chelsea got a great chance to kill the game after Squillaci gifted the ball to Anelka, he then rounded the keeper but saw his shot hit the side netting!
Arsenal also got a great chance to grab an equaliser but Chamakh who was causing problems in the air headed just wide.
Chelsea were then awarded a free kick outside the box. Alex took the free kick and scored it with an absolute belter of a goal! A rocket shot which no goalkeeper would have kept out went sailing past the hands of Fabianski in the Gunners goal.
The final score ended: Chelsea 2-0 Arsenal.
