Arsenal moved to within a point of the top four with their first win in four games with Piere-Emerick Aubameyang’s 10th goal of the season making the difference.
Emery once again deployed a 3-4-2-1formation to break down Bournemouth, which was last used in the Europa League match against Quarabag last month which ended 3-0 in favour of the Gunners.
Alex Iwobi’s fabulous pass set up Sead Kolasinac for a low cross that Aubameyang converted from close range to clinch a hard-fought win.
An eye-catching own goal gave Arsenal the lead. Lucas Torreira had seized on a careless pass to advance and fire a shot against the post. Kolasinac got forward on the left and clipped a pass towards Aubameyang inside the box. It never reached him – Jefferson Lerma got there first and inadvertently slammed the ball past Asmir Begovic.
That followed a spell of dominance for the Gunners, and Iwobi tested Begovic with a curler. But Bournemouth – aggrieved to be behind after their strong start – equalised against the run of play on the stroke of half-time.
The defence tried hard to contain Josh King, the Bournemouth attacker, who continued to terrorise them and succeeded in sweeping a shot past Bernd Leno.
Arsenal got the job done, the second half as Iwobi dissected the Bournemouth defence and Kolasinac’s low cross was perfectly weighted for Aubameyang to poke the ball into the net.
Mkhitaryan could have sealed the points when he was set up by Aubameyang on the break, and Bournemouth almost equalised when Lerma smashed a late shot against the post.
