Emiliano Martinez 7/10 – Another very assured performance from the young Argentine, who looks to have all the makings of a top-flight keeper. Wojciech Szczesny’s spot could well be under threat moving forward.
Calum Chambers 7/10 – Keen to make an impact against his former club, the summer signing made a number of marauding runs down the right flank and managed to get the better off Dusan Tadic on a number of occasions.
Laurent Koscielny 7/10 – The Arsenal defence looks much more comfortable with the Frenchman back, with his pace and positional awareness more than missed in recent weeks.
Per Mertesacker 7/10 – Coped well with the power and presence of Graziano Pelle, and wasn’t too troubled by a couple of lofted balls over the top during the early stages of the match.
Nacho Monreal 6/10 – Solid in defence, keeping both Tadic and Shane Long quiet for long stretches, but didn’t contribute much going forward.
Mathieu Flamini 6/10 – Held things down in front of the back-four in no-nonsense fashion, but it’s clear that Arsene Wenger needs more of an orchestrator for the role.
Aaron Ramsey 5/10 – Looks off-colour at the moment and could perhaps do with some time on the bench. It’s not just his goal-scoring which has left his game but also his passing skills, too.
Santi Cazorla 6.5/10 – Wasn’t quite as influential as in the past two matches but had his moments, including one excellent ball through to Welbeck in the first-half which the striker should have finished.
Alex Oxlade-Chamberlain 6/10 – Forced an impressive save from Fraser Forster with an effort in the 26th-minute, and linked up well with both Welbeck and Sanchez. There were boos from the home crowd when he was taken off for Giroud in the second-half.
Alexis Sanchez 7/10 – It wasn’t his best performance in an Arsenal shirt but, once again, he produced the game-changing moment when the pressure was on. Switched flanks over the course of the night, before popping up in the middle to slot home the late winner.
Danny Welbeck 5/10 – A difficult night for the £16 million man, who proved wasteful in possession and missed a few chances which a better finisher would have put in the back of the net.
Olivier Giroud (Oxlade-Chamberlain 65) 7.5/10 – Made an immediate impact after coming on, testing Forster with a thumping shot, before a fine flick created a chance for Welbeck which the Saints keeper stopped again. Was even involved in the build-up to the winner, too, after almost opening the scoring himself with a looping header which was tipped just wide.
Lukas Podolski (Welbeck 81) N/A – Another late cameo, with not enough time to make an impact.
