Lukas Podolski struck twice as Arsenal came from behind to beat West Ham and move back above Everton in the race for a Champions League place.
Matt Jarvis headed the Hammers in front as they threatened to extend Arsenal’s winless league run to five games.
But Podolski levelled with a shot on the turn two minutes later for the impressive FA Cup finalists.
Olivier Giroud’s classy finish and Podolski’s driven second sealed the win as Arsenal moved up to fourth.
