Came in for compatriot Szczesny and made some excellent saves, particularly as he denied Suarez and Sturridge in the second half.
Caught out early on as Strurridge ran in behind him and went through on goal, but responded well to deny the visitors space.
Good body positioning as Sterling looked to square him up and dribble past him. Beaten on a few occasions but always tenacious.
Intriguing battle against Suarez. The Spaniard sometimes looked uncomfortable but stuck to his task well. Fortunate to only receive a yellow card when he trod on Allen's ankle in the first half.
Leader of the line at the back. Strong in the air and made well-timed interceptions. Suited the German that Arsenal defended fairly deep against Liverpool's attacking speed.
Unsurprisingly made sure he was among the players booked but set the tone in midfield as he snapped into tackles and looked to deny Liverpool space in between the lines.
Some efficient passing in central midfield and tried to start counterattacks, but his play was a little predictable.
Some good positioning and accurate passing from Arsenal's record signing but he seemed to struggle with the pace of the game in the second half.
A shock selection as he made his first start for the Gunners since his summer transfer. Faded in the second half but on the whole caused a nuisance in his own ungainly way. Great chest down and shot in the build-up to the opener.
A terrific performance on the right side of Arsenal's attack. Scored the opening goal with a precise low finish before setting up the second. Full of ideas and had the composure to make the right decisions in the final third.
Very little involvement for most of the match but produced a great run and finish to score Arsenal's crucial second goal. Looked disheartened when replaced by Cazorla in the 69th minute.
Looked rather uncomfortable throughout the game and was wrong-footed for both Arsenal goals.
Composed on the ball but looked uncomfortable against Sanogo's physicality and perhaps could have done more for Podolski's goal.
Strong and powerful but shown up at times by Oxlade-Chamberlain's speed and trickery, while his use of the ball was often poor.
Won his fair share of headers up against Sanogo and made some well-timed challenges to snuff out Arsenal attacks.
The youngster was generally strong defensively and increasingly charged forward to support attacks.
Neat and tidy in central midfield as he kept the ball with simple, accurate passes. Not afraid to put himself about, either.
Some real moments of class from the Brazilian, particularly in the second half as he looked to knit together attacks. Some lovely link ups with Suarez and Sturridge.
The winger jinked past defenders with ease at times but lacked the quality of end product he showed against the same opponents eight days earlier.
Showed his class with a superb pass to put Sturridge through on goal and a clinical penalty in the second half. Dropped too deep in the first half but more of a driving force after the break.
The Uruguayan's movement and skill caused Arsenal's defence all sorts of problems. Won one penalty, should have had another and always looked so dangerous in the penalty area.
Intelligent runs in behind always a threat for the visitors - and he really should have done more damage. Three times he went through on goal but failed to provide the finish.
