West Ham beat Chelsea at the London Stadium thanks to a bizarre goal by Arthur Masuaku three minutes from time.
The Hammers fell down twice in the game, the first time when Thiago Silva headed home Mason Mount’s corner just before the half-hour mark, but the hosts equalized five minutes before the break thanks to Manuel Lanzini’s penalty.
When Chelsea conceded the penalty, they were responsible because Jorginho put his goalie under undue pressure, and then Edouard Mendy tried to take on Jarrod Bowen and brought him down in the box.
Mount put the Blues ahead on the stroke of halftime when he volleyed in a cross-field ball from Hakim Ziyech, but Bowen’s 20-yard left-footed drive levelled the game once more.
Masuaku attempted a cross from the left flank, but his effort squeaked in at the near post past the leaping Mendy, giving David Moyes’ side all three points.
West Ham will stay in fourth place thanks to the win, but Chelsea’s reign at the top of the Premier League seems unlikely to last the weekend.
