Goals from Mesut Ozil, Theo Walcott and substitute Olivier Giroud threw West Ham right back into the relegation mixer and eased the mounting pressure on Arsene Wenger.
The Gunners came into the match amidst growing dissatisfaction from fans surrounding the future of their manager and an almost half-full crowd reflected just that.
A tepid first half, in which the home side mustered only one shot on target, didn’t bode well. But Arsenal then turned on the kind of football they’re renowned for, Ozil’s speculative shot bouncing in front of Darren Randolph and setting them on their way.
Randolph may have been at fault for the opener but had little chance with the others, Alexis Sanchez and Ozil combining to set up Walcott before Olivier Giroud came off the bench to settle matters with a beautiful curling shot inside the far corner.
Victory for Arsenal means they climb back above Manchester United to fifth in the table but for the unhappy Hammers, five defeats on the bounce leaves them only four points above the drop zone and leaves Slaven Bilic in an uncomfortable position that his opposite number will be well accustomed to.
Arsene out of danger again? That’s the kind of performance that will have Arsenal purists purring but they’ve been far too inconsistent this season. Fans won’t be convinced just yet.
