Pierre-Emerick Aubameyang scored twice as Arsenal hung on to maintain pressure on the top four and leave Burnley in the Premier League bottom three at Christmas.
Mesut Ozil – making a first start in six league matches – produced a sublime defence-splitting pass to Sead Kolasinac for Arsenal’s opener, with the defender picking out Aubameyang for his 11th league goal of the season.
Remarkably, after 18 top-flight games, Arsenal led at the interval for the first time this season and it took the Gunners fewer than three second-half minutes to double the advantage, Aubameyang’s powerful finish completing a quick counter-attack.
Burnley kept to their task though and Ashley Barnes brought the Clarets back into the contest on 63 minutes with a low finish after the home side failed to clear.
The home fans grew increasingly nervous as Burnley pushed for an equaliser but Alex Iwobi scored from close range in stoppage-time to ensure the Gunners moved level with fourth-placed Chelsea ahead of the Blues’ match against Leicester.
