Ben Chilwell and Kai Havertz struck to overturn Michail Antonio's opener and give Chelsea a 2-1 win at Stamford Bridge on Saturday.
Antonio tapped the Hammers into a 62nd minute lead, only for Chilwell to level 13 minutes later, before late drama swung the contest Chelsea's way.
Antonio scored from close range from a corner after Declan Rice kept the ball alive at the back post and knocked back across goal.
Chilwell restored parity 15 minutes from the end, latching onto a long diagonal ball into the box before squeezing past Łukasz Fabiański from a tight angle.
Then, Kai Havertz converted with two minutes left to make it 2-1.
Maxwel Cornet looked to have equalised mere seconds later, only for a VAR decision to rule it out.
