Had more help from his defenders than a goalkeeper might usually expect with more than one goalline clearance, but twice denied Gervinho when through on goal.
Struggled to cope with the athleticism of Gervinho and as a result was not as threatening going forward as usual.
Cannot be faulted for effort but struggled badly with the pace of Theo Walcott.
Like Martin, Barnett was defensively solid but his distribution after winning the ball was frustrating and let him down.
His heroic block of Theo Walcott's goalbound shot in the first half was cancelled out by an error that led to Arsenal's second goal. Otherwise, a brave and intelligent display.
Had his moments but was generally subdued by Alex Song before being withdrawn in the second half.
Quieter than Paul Lambert would have hoped. Moved out wide in the second half after starting in attack but Laurent Koscielny kept a lid on him.
Frustrated Aaron Ramsey fairly effectively before being withdrawn for winger Elliott Bennett at halftime.
Like Crofts, did his defensive job well but struggled to impose himself when Norwich had possession.
Made sure Mikel Arteta was kept under close attention but did not offer too much else.
A real handful, he caused plenty of problems through brute force. Took his goal well but the Arsenal defense started to adjust to his power as the game wore on.
Relatively untroubled. Might have hoped to get a stronger hand to Norwich's opening goal.
More physically ready for the battle ahead than his partner, he was particularly strong defending set-pieces.
His horrific error came through a simple lack of awareness and concentration. Seemed to wise up to the physicality of Steve Morison after that.
Defensively solid, containing Anthony Pilkington well when he moved to Koscielny's flank. Not comfortable advancing to support Theo Walcott.
Look to advanced as much as possible down the left but his lack of pace puts him in trouble when his marker defended aggressively against him.
Neat and tidy, he rarely gave the ball away but struggled to find space in a packed central midfield.
As usual, defensively very aware and played a superb through ball to release Robin Van Persie for Arsenal's second.
Playing off Robin Van Persie, he was involved plenty but frustratingly couldn't quite get his final ball right.
Bright when he received the ball, but not always the busiest off it. Might be disappointed not to have scored but gave Norwich plenty to think about.
R. van Persie
The Norwich defense did enough to stop Arsenal from playing through its captain but he is quite simply red hot and a lethal threat in front of goal. Two more for his tally and another match-winner.
Tired as the match wore on but during the first half he was a constant thorn in the Norwich side. Created Arsenal's first goal.
