At half-time, the Gunners led 1-0 in a low-key match, thanks to Olivier Giroud's firm header from a corner kick. West Brom improved after the break but there were no further additions to the scoresheet, giving Arsenal the three points.
Arsenal first half analysis
SZCZESNY—Hasn't had a lot to do, though spilled a long-range effort from Dorrans.
SAGNA—Got forward well early on, not so much after the opening goal. Gave the ball away once or twice in his own half.
KOSCIELNY—Good on the cover, passing the ball out well.
MERTESACKER—Has headed a few isolated West Brom crosses from deep clear.
MONREAL—Like Sagna, has gotten forward to good effect a few times, perhaps more often than the right-back.
ARTETA—Cool, composed, but not really dictating the game.
FLAMINI—A bit more energy and determination about his game. Has made a few surging runs forward.
CAZORLA—Looked more involved after moving central, having started on the right.
OZIL—Some neat touches and good movement to find space, but should be making more of the room afforded to him against sluggish and slow West Brom defence.
PODOLSKI—A few half-chances have fallen his way, hasn't really created much himself.
GIROUD—Well-taken goal. Has led the line well, linked up play nicely.
Arsenal second half analysis
SZCZESNY—Made a few routine saves but nothing spectacular. Did well with aerial balls in his six-yard box.
SAGNA—Pinned back all half, Brunt gave him a few issues.
MERTESACKER—Came under pressure with Sessegnon dropping off and, later, the physicality of Anichebe, but stood firm to the task.
KOSCIELNY—Played well, cleared danger plenty of times, contributed to another clean sheet.
MONREAL—One of his better performances, though didn't get forward much after the break.
ARTETA—Subbed midway through the half, no real impact.
FLAMINI—Couldn't get forward to good effect in the second half. Outrun and out-battled on his own at times.
CAZORLA—Not heavily involved as West Brom took control.
OZIL—Made good runs off the ball to provide an outlet on the counter. Final ball just lacking at times.
PODOLSKI—Should have scored from one of two presentable chances, but was a good counter-attack threat.
GIROUD—Man of the match for the Gunners for his link up play, holding up the ball and of course his match-winning goal.
KALLSTROM—Not involved enough, missed a good headed chance.
ROSICKY—Looked good initially but faded quickly.
VERMAELEN—Played final 10 minutes at left-back.
