Shaky against Norwich and could have conceded a penalty after just 15 minutes after a coming together with Afellay. Got nowhere near the ball but the Dutchman's theatrics spared him.
His 100th appearance for Arsenal but was booked after just 15 minutes.
Seemed to just stand and watch as Afellay went past him before collapsing over Mannone early on.
A strong first half, particularly when he launched himself bravely to block Farfan's shot.
Impressive from the youngster. Screened his defense well but also looked to get forward when he could. Showed plenty of energy and his first touch was excellent. Was within a whisker of setting up the opener just after the break.
Arsenal's main man once again. Looked a threat whenever he had the ball, superb in possession.
Did not look too comfortable in his position further forward. Worked hard, perhaps lacked the pace to trouble the Schalke defense
An absolute stinker from the Brazilian. Yes he was isolated far too often. But he was guilty of frequently ball-watching and just could not cope with Farfan and Ushida's pace.
Produced a couple of good crosses for Gervinho early on, but faded as the half wore on. Showed no interest in getting back to help out Dos Santos
At his frustrating best, his movement was good and he had a couple of great chances but dawdled. Looked short of confidence and indecisive.
A virtual spectator in the first half and had even less to do in the second half. Cannot had expected such an easy evening at the Emirates.
Won virtually everything in the air, good pressure on Gervinho in the opening minutes to deny the Arsenal man and again just after the break.
Handled Gervinho confidently and made a great block from a fierce Vermaelen shot in the first half. Missed a great chance to score just after the break smashing an easy chance over the bar from 12 yards.
Could not get on the ball initially, but grew into the game as the first half wore on and helped Schalke dominate the second half.
A very quiet first half but became more of an influence after the break with some good delivery from the left.
Did OK defensively but became a real attacking threat down the right and along with Farfan gave Dos Santos a torrid time.
Took a while to get going as Arsenal dominated the early possession. Not afraid to put his foot in and was little surprise to see him booked in the first half. Substituted at the break
Rightly booked for diving after a great ball from Farfan, and if he had not been so eager to go to ground he might have received more sympathy from the ref. Sealed with win with a confident finish from close range.
Has spoken of his desire to play in England and looked desperate to impress. Was lively and hard working but made little impact in truth and was substituted just after the hour mark.
Became a real threat for Schalke in the first half. His pace and trickery were too much for Dos Santos to handle. Set up Howedes beautifully after the break and put the second on a plate for Afellay.
Hardly saw the ball in the first half but was then presented with a sitter right on halftime which he wasted by shooting wide after great work from Ushida. Same story in the second half but a superb turn and shot to put Schalke ahead.
