Three goals in nine second-half minutes by Arsenal turned Monday’s Premier League match at London Stadium upside down, with West Ham United defeated 3-1 by the visitors.
Angelo Ogbonna had capped an impressive first half for the home side with a bullet header seven minutes from the interval, giving the Irons a deserved advantage.
However Gabriel Martinelli, Nicolas Pepe and Pierre-Emerick Aubameyang struck after the hour to give victory to Freddie Llungberg’s Gunners.
