Barely had anything to do in the first half but still looked like conceding. Lucky not to be punished when he let a corner slip through his hands and then failed to collect a cross moments later, as well as slicing a kick for good measure. No chance with the goal.
Solid enough performance. Put some good tackles in and won his headers. Helped out by Arsenal's lack of attacking penetration.
Held his own for the most against Oxlade-Chamberlain, who was not as his best, but looked nervy at times.
Unfortunate not to have a penalty early on. Assured as ever on the ball.
Should have scored before Ramirez's goal. Gave away the soft foul on Arteta that lead to the Gunners' goal. Found the side netting when presented with a good chance of his own but created a few decent openings late on to relieve some pressure.
Unfortunate to score an own goal as he tried to stop Walcott's free-kick, which Koscielny would have probably put in anyway. Forced Szczesny into a good save in the second half. Put a shift in and tracked back well.
Looked a bit slow on ball and struggled as a right-back. Didn't give Saints the same outlet as Clyne offers but was solid in defence.
Some sloppy passes on occasions but brought the ball out of defence well. Had a hand in the build up to the goal. Broke up numerous attacks.
Brought the ball forward with intent at times but failed to find a final pass.
His direct and dangerous runs worried Arsenal but often lacked final product. Took his goal extremely well, though. Possibly unlucky to be penalised for a push when he had the ball in the net a second time. Rightly received an ovation when brought off late on.
Could have scored ten minutes in had he held his run. Looked unfit and needed an extra yard of pace at times.
Nothing to do in the first 45, and had no chance with Ramirez's goal. Didn't command his area all that convincingly. Brilliant save to deny Do Prado and then an even better one from the resulting corner, though. Weak parry from Schneiderlin cross would have led to a Saints second if any red shirts were lurking.
Put in a few good crosses. Made a fine last-ditch challenge on Guly which unfortunately for him still led to the opening goal. Didn't look as sharp as usual.
Did not show enough power in the tackle in the lead up to the first goal and gave away the ball cheaply at times. Had some joy going forward. Arsenal may well have scored late on had he found a team-mate.
Dealt with Lambert and made one goal-saving tackle on Ramirez but could have conceded a penalty against Yoshida. Could have been more commanding at times, the first goal for instance.
Involved in some lack-lustre marking and was part of a defence who failed to clear their lines for the opening goal. Did make some important blocks and was lurking behind Guly for the own goal.
Had a decent early strike deflected just wide, but was largely quiet. Did move the ball well with Wilshere at times. Looked in need of a rest and got one when he was brought off in the second half.
Kept things ticking. Won the free-kick which led to the own goal. Went close with a vicious strike in the second half.
Nice interplay with Cazorla in and around Saints' area but failed to cut through their defence. Battled hard as always, though.
Looked dangerous when running with the ball and offered some decent crosses. Not the best of returns to the south coast and was brought off with 15 minutes left.
Saw an early shot blocked but was quiet from then on. Gave away the ball in the build up to Saints' opening goal. Brought off early in the second 45.
Good delivery led to own goal and had the ball in the net himself but it was, rightly, disallowed for offside. Didn't do much else on his St Mary's return, though, as he failed to get involved and wasted a number of positions with sloppy play.
Came on for Cazorla with 15 minutes left.
Came on for Oxlade-Chamberlain for 15 minutes in the second half. Found the side netting late on.
Came on for the below-par Podolski early in the second period but added little to an already less-than-impressive attack.
