GOAL - Chelsea 2-1 West Hampublished at 21:46 British Summer Time 15 August 2016
Diego Costa (89 mins)

And that's the winner.
Nemanja Matic goes long, lofting the ball upfield towards the head of Michy Batshuayi, who flicks it on for strike partner Diego Costa.
Costa, who should not be on the field, takes a touch and strikes a low effort through the legs of James Collins and into the bottom corner.
West Ham goalkeeper Adrian was done after taking a step to his left. It proved fateful.
Chelsea boss Antonio Conte goes running down the touchline in celebration before hugging the fans in the front row. Incredible scenes.
