West Ham came from behind twice to beat Premier League leaders Chelsea at the London Stadium in the early kickoff on Saturday.
The Blues took the lead with 30 minutes gone as Thiago Silva headed in the opener, before the hosts were awarded a penalty when Edouard Mendy tripped Jarrod Bowen in the penalty box.
Manuel Lanzini made no mistake from 12 yards to draw the Hammers level, only for Mason Mount to restore Chelsea's lead almost immediately with a superb volley. West Ham, however, levelled the score early in the second half through Bowen's smart finish, before Mendy allowed Arthur Masuaku's cross to beat him at the near post as David Moyes secured a famous win.
