Unai Emery and Arsenal claimed their first victory of the season with a hard fought 3-1 defeat of West Ham United at the Emirate Stadium.
Issa Diop’s own goal and a stoppage-time Danny Welbeck strike sealed a 3-1 the the win after losing two previous games against Manchester City and Chelsea respectively..
Marko Arnautovic gave the visitors a 25th-minute lead, with Nacho Monreal restoring parity five minutes later.
An entertaining and error-strewn contest continued to flow from end to end but an injury to Arnautovic robbed West Ham of their prime attacking threat before Diop fumbled.
Welbeck came off the bench to blast in from close range, ensuring Manuel Pellegrini’s fledgling West Ham tenure stands at three defeats out of three.
