Diego Costa handed Antonio Conte a Premier League victory at his first attempt with a dramatic 90th minute winner over West Ham at Stamford Bridge.
The Spain striker was fortunate to still be on the pitch after receiving an early booking for dissent and then avoiding a second yellow for a second-half foul on Hammers goalkeeper Adrian.
Eden Hazard had given the hosts the lead from the penalty spot two minutes into the second period after Michail Antonio brought down Nemanja Matic in the box.
