His catching was a little sloppy but his positioning was good and communicated well with his defence.
Caught out by Marseille's initial ambition but strolled through the rest of the game in an encouraging first game alongside Vermaelen.
Initially struggled to deal with the explosive pace of Ayew and his distribution was woeful but grew in authority as Marseille became less ambitious.
Arsenal's most reliable defender showed how important he is to his team with a confident, error-free display in his first Champions League group match for two years and only his second start in three months.
Got caught out by Marseille's corking start but settled down to dominate the midfield with a tigerish display.
Wasted a good first-half chance to put his team ahead but looked full of confidence and his distribution was excellent at times in the opening period. Faded after the break and withdrawn with 25 minutes left.
Attacked with great eagerness but frequently went AWOL when he was required to defend. Got away with it.
Unable to reproduce the heights of the Chelsea match with an inconsistent display. His pace got him into some good positions but then wasted them.
Looked a little off the pace and heavy footed. It is early days in the south Korean's Arsenal career but needs to show more if he is to be considered an able deputy to van Persie. Subbed after an hour.
His pace and movement got him into some good positions but was often guilty of being a little too selfless and not direct enough. Subbed with 15 minutes left.
Made a fine first-half save from Walcott and commanded his penalty box confidently.
The Marseille skipper provided some reliable distribution from his left-back position and generally kept Walcott on a tight leash.
Rarely ventured forward from right-back but defended solidly.
His recovery pace saved Marseille on a few occasions when Arsenal looked like getting behind the French team.
DIctated the early play as he regularly located the smart runs of the Marseille runners. His work-rate was excellent throughout.
Lively early on when he linked up well with his more fleet-footed team-mates and had a lively spell after the break with his neat passing and low centre of gravity.
Energetically anchored the midfield, although his distribution was hit-and-miss.
The strapping centre-forward worked his socks off and kept Arsenal's centre-halves busy but did not manage to get behind them. Subbed late on.
His display mirrored his team's. Started on fire but then went flat. Subbed midway through second half.
Caught the eye with his explosive pace and trickery on the left flank. Could and possibly should have given his team an early lead when he slid narrowly wide from close range.

Struggled to make an impression in the playmaker role other than with a few rash tackles.
R. van Persie
Given a standing ovation when he replaced the disappointing Park. Nearly won the game with an audacious lob.

- 12 C. Kaboré
Manoeuvred himself into some good positions through force of will rather than any great pace.
Replaced Valbuena with 16 minutes left but his passing radar was on the blink.
Helped shore up the backline late on.
