Made one brilliant stop with his foot to deny Toure the equalizer from a Gerrard free-kick, but was otherwise rarely troubled.
A calming influence at the heart of the defense. Predictably unbeatable in the air, though Suarez and Sturridge found space whenever they dropped deep to receive the ball.
Outpaced Cissokho to provide the cross for Cazorla's opener and showed great energy at both ends throughout.
Generally acquitted himself well against the deadliest strike partnership in the league, although Sturridge made him look silly with one drop of the shoulder in the first half.
Ensured Flanagan had little to no influence as an attacking presence and got forward well, though his delivery was often poor.
His dynamism and tidy passing ensured Arsenal comfortably won the midfield battle, even if he rarely threatened the goal himself.
Didn't touch the ball as frequently as he is accustomed, but his runs from deep made him Arsenal's chief goal threat and he showed superb persistence and composure to follow up his own header with the opener.
Not at his rampant best, but always had the Liverpool defense on edge and made sure he did something sensible whenever he couldn't do something amazing. Lit up the evening with a sensational strike to double his side's lead on the hour. Out of nothing this appears to be shaping up to be his season.
His influence is often understated as he flits in and out of the game, but he always oozes class and lifts those around him. More than played his part as the Gunners confidently dominated possession in the first half, and played a lovely dink into Ramsey to set up the Welshman's screamer after the break.
Led the line brilliantly with strength, intelligence and technique. Not afforded many chances, but some of his lay-offs were Ozil-esque and gave his midfielders opportunities to do damage. Missed a golden chance to double his side's lead after the break.
Overcame some dodgy kicking early on and was generally solid. Could do nothing to stop either of Cazorla's efforts which led to the opener, or Ramsey's screamer.
Forced Giroud to do most of his work with his back to goal and was powerless to prevent both Arsenal goals.
Left for dead by Sagna in the build-up to Arsenal's opener and looked drained of confidence and off the pace from then on. Hauled off at the interval.
One of the finest performances of his young career came at the Emirates in August 2011, but this occasion appeared a little too much for him. Couldn't deal with Arsenal's attacking movement and couldn't influence the game going forward.
Typically cultured on the ball and unlucky to be denied a goal against his former club by a superb Szczesny save. Caught out for Cazorla's goal and a slow reaction created a gilt-edged chance for Giroud.
Showed good physicality and tenacity in one-on-one duels, and was not directly responsible for either Arsenal goal.
One of his typically excellent set-piece deliveries set up Liverpool's best chance for Toure, but he was otherwise a peripheral figure.
Had too many creative midfielders to deal with to be an effective shield in front of his defense. Not his best day.
Solid rather than spectacular - first in central midfield, then at right wing back - but couldn't prevent the Gunners dominating possession until they had scored the goals they needed.
A huge threat all evening, brimming with purpose, trickery and imagination. Will feel justifiably aggrieved that his quick free-kick was not allowed to stand, and hit the post with one clever effort from a tight angle. Showed no hangover from his failed attempts to engineer a move to north London in the summer, though he did spurn a very good chance in the closing minutes.
A willing runner all game, but most of what he tried failed to come off and, starved of possession, his teammates could not provide the service he requires.
