Alexis Sanchez scored twice in the first half as Arsenal strengthened their top four bid with an easy win over an unthreatening West Brom side.
The game was played in front of a number of empty seats, but those who were there had the pleasure of watching an early goal after Sanchez’s shot dribbled past Foster into the bottom corner of the net.
The Gunners kept looking to press their home advantage over the Baggies, when Mesut Ozils shot was blocked by Jonny Evans and Aaron Ramsey who volleyed but shot wide.
West Brom with Saido Berahino up front offered little attacking threat from open play, but they very nearly scored when McAuley’s header rattled the crossbar.
The sound of gasps from the crowd echoed the Emirates as Bellerins assist to Ozil saw the ball slip through Fosters legs slowly crawling over the line- but Craig Dawson was there to clear.
Fortunately, Arsenal did get a second in the 38th minute when Sanchez curled a free kick through the defensive wall, with Arsenal players moving to the side to let the ball pass through.
After being 2-0 down at half time, Tony Pulis introduced Salomon Rondon to play alongside Saido Berahino.
Although Rondon made a small impact on their attacking play, it was Arsenal who continued to dominate with Olivier Giroud having a shot saved and Ozil having two shots blocked.
Rondon nearly caused an Arsenal upset in the 73rd minute when Petr Cech missed a corner but Rondon did not react quickly enough to score with the goal gaping open.
Substitute Joel Campbell came on with a fierce attacking mentality as he shot narrowly wide of the post in the closing minutes of the game.
A comfortable win for Arsenal, but fans were still holding up banners at full time calling for the Arsenal manager to leave.
