A very easy night for the Pole. Never seriously tested by Napoli.
Communicated well with Koscielny and looked in total control and the hosts thwarted rare Napoli attacks.
The Frenchman's aggression in the challenge and reading of the game meant Pandev never caused Arsenal any problems.
Didn't have any trouble with attacks down Arsenal's right side and was tidy on the ball.
Solid display from the left back. Defensively untroubled and provided width when the hosts had the ball.
Continued his excellent recent form as he snapped into tackles in midfield, denying the likes of Hamsik any time or space to operate. Maybe lucky with a couple of over-zealous challenges but set the tempo for the hosts.
The Czech midfielder returned from injury and slotted in like he had never been away. Strong understanding with Ozil and Ramsey while providing incisive passes in the final third. Replaced by Wilshere in the 63rd minute.
The German summer signing put Arsenal ahead in the eighth minute with an exquisite finish from 18 yards, the best moment in a sensational display. Created the second goal for Giroud and constantly caused Napoli problems with is clever movement and his intelligence on the ball.
Dynamic performance from the in-form Welshman in central midfield as he linked up superbly with team mates, drifted in between the lines and looked to make runs into the penalty area. Great vision to provide the assist for Ozil's opener.
Doubled Arsenal's advantage from close range in the 15th minute and led the line with clever movement, strength and skill.
The on-loan Liverpool goalkeeper could do nothing about either of the hosts' goals but was otherwise solid in dealing with Arsenal pressure. Stayed big to deny Koscielny in the second half.
Lack of mobility exposed by Arsenal's fluent movement in the final third and lacked positional awareness.
Terrible performance from the defender. Slow, clumsy and not up to the pace of the game. Summed up when he gave the ball away for the second Arsenal goal.
Like Behrami, failed to provide sufficient protection for the defense and attempted some pointless long-range shots in the second half.
Sat in front of the back four but the Swiss could not handle Arsenal's attacking midfielders and lost Ozil in the build-up to the opener.
Shambolic performance from the Colombian, particularly in the first-half as he lacked any awareness and effort levels were poor, especially to allow Ramsey to cross for the opener.
Poor positional play exposed and seemed to need too many touches when in possession.
Hailed as Napoli's star man but it was only his haircut that really caught the eye. Showed a few glimpses but denied space by Arsenal and missed Higuain's movement in front of him.
One or two nice drops of the shoulder but outnumbered and outmuscled by Arsenal shirts.
The Spaniard worked hard but never caused Arsenal's defense any problems before being replaced 13 minutes from time.
Isolated and ineffective as the lone striker before being substituted in the 61st minute. Could not get away from the Gunners defenders and lacked movement. The Italian side badly missed the injured Gonzalo Higuain as the leader of their attack.
