Substitute Kai Havertz scored a late winner as Chelsea rallied from a goal down to defeat West Ham, who had a 90th-minute Maxwel Cornet equalizer ruled out.
The Hammers frustrated Chelsea in a first half that saw plenty of home possession but no shots on goal for either side, and Michail Antonio scored from a rare attack after 62 minutes, looking to have executed their gameplan perfectly.
After Blues goalkeeper Edouard Mendy failed to deal with a corner, the forward bundled in from close range, but the visitors’ lead was erased 14 minutes later.
