Eddie Nketiah came off the bench to score the winner Arsenal snatched a 2-1 victory over a drastically-improved West Ham at the Emirates Stadium.
The Hammers were unrecognizable from the side that succumbed to Newcastle on the opening day, producing a display packed full of endeavour and energy to stifle the Gunners for large parts.
Arsenal took the lead against the run of play on 25 minutes when Alexandre Lacazette powerfully headed Pierre-Emerick Aubameyang’s cross home, but it was cancelled out on the stroke of half-time by Michail Antonio.
