The Hammers had taken the lead just after the hour-mark when Michail Antonio found the net but it was the Blues that looked to be taken the points thanks to an equaliser from Ben Chilwell and Kai Havertz’s late strike.
However, there was still time for more drama in the game as Maxwell Cornet stunned Stamford Bridge by rifling a loose ball into the top corner of Edouard Mendy’s net.
Referee Andrew Madley was advised to review the decision to award the goal after VAR official Jared Gillett spotted an alleged foul on Blues keeper Mendy.
Madley made his way to the pitchside monitor and revised the decision, much to the announced of West Ham manager David Moyes.
Speaking after the game, he told Sky Sports: “It is a scandalous decision, absolutely rotten from one of the supposedly elite referees,
“It doesn’t say much about whoever sent him over from VAR as well. It is an unbelievable decision against us.”
Sunday afternoon brought confirmation the Premier League have now asked the PGMOL to review the decision and a similar situation at Newcastle United when an own-goal by Crystal Palace defender Tyrick Mitchell was surprisingly disallowed.
The Eagles left-back seemed to push Magpies midfielder Joe Willock before the ball diverted off his chest and into his own net.
Willock’s momentum took him into Palace keeper Vincente Guiata, and that brought the decision to disallow the goal following a VAR review.
Magpies manager Eddie Howe said: “I thought it was a push on Joe Willock in the build-up to the ball coming in. Without that push, there’s no way Joe would have gone in with that force.
“So for me, it’s not a foul, if anything, it’s a penalty if it’s not a goal.”
