Kai Havertz earns Chelsea controversial win as West Ham rue disallowed goal

The slowest-burning of games developed into chaos and, ultimately, a Chelsea victory that for long periods had seemed unlikely. A largely leaden showing seemed to have been punished by Michail Antonio after half-time but two substitutes, Ben Chilwell and Kai Havertz, finished smartly and ensured a textbook away showing from West Ham went unrewarded.Even after Havertz’s late winner there was a heartstopping moment for Thomas Tuchel when Maxwel Cornet, who had earlier struck a post, capitalised upon an Édouard Mendy fumble to score; the visitors celebrated wildly but the goal was ruled out via a VAR review for a clip on the goalkeeper by Jarrod Bowen. Chelsea needed the points badly but, after such an extravagant transfer window, will hope for a more consistent level of performance.
