Nothing he could do about West Ham's opening goal, didn't have much else to do in the first half.
An improvement from his recent displays; kept Matt Taylor occupied by making numerous forward runs combining with Walcott down the right flank. Should have done better from good crossing positions.
Organised the Arsenal defence well throughout the match apart from a couple of nervy moments from West Ham set-pieces.
Struggled with a couple of aerial duels against the physicality of Carlton Cole but had an uneventful second half.
Bombed forward down the flank allowing Lukas Podolski to vacate the left wing and drift in field to great effect. Was rarely troubled by West Ham as an attacking threat.
Top of the Match
Made some driving runs to create momentum for the hosts and played a nice flick to set up Podolski's goal. Always looked to penetrate West Ham's two lines of four throughout the contest.
Played well in the deeper midfield role by keeping Arsenal's move ticking through the middle of the park. Made a crucial goal line clearance to deny Cole in the first half.
Was back to his old self, getting involved in the match whenever he could. Always looked for Walcott and Podolski in between the lines of the West Ham defence. Got himself on the scoresheet with a cheeky finish.
Took his goal brilliantly when Arsenal were up against it. Was involved in plenty of flowing Arsenal moves in the second half, providing a good assist for Walcott's goal.
Clumsy performance from the Frenchman in the first half, he misplaced two key passes early on which could have had Arsenal ahead but made amends with a well taken goal in the second half. Came alive and led Arsenal to an emphatic win with two well taken goals.
Was Arsenal's most dangerous attacking threat in the first half and played a big part in the second half goal flurry. His pace troubled O'Brien and Tomkins all night long.
Was a late substitute as Arsene Wenger looked to sure up his defence, made one good challenge and had very little to do otherwise.
Came on in the second half and gave a disciplined performance, helping Arsenal sure up the result.
Came on for Giroud with 20 minutes to go. Showed some decent touches but wasn't allowed to influence the game as he wanted.
