West Ham head coach David Moyes did not mince his words after his side lost to Chelsea 2-1.
The Hammers equalised late in the game through Cornet, but their goal was chalked off by VAR. The system decided that Bowen fouled Mendy shortly before the goal.
"It is a scandalous decision, absolutely rotten from one of the supposedly elite referees," Moyes told Sky Sports.
"It doesn't say much about whoever sent him over from VAR as well. It is an unbelievable decision against us.
"The goalkeeper comes to take it and fumbles it out of his hands. Then he acted as if it was a shoulder injury.
"I'm amazed that VAR sent the referee to the screen. It was a ridiculously bad decision.
"Today there is no excuse for that not to be a goal, none whatsoever. The sad thing is that this is the level of our elite refereeing at the moment.
"They've got new people in charge who are trying to do something. I've lost faith in them today in the people who are putting up for VAR. After watching it, I can't see how the goal was not given.
"The referees said they were going to cut back on soft challenges and that was unbelievably soft.
"Referees can make mistakes. I do not see that in a million years. I'm more embarrassed for the guy in VAR than the referee because that's telling me someone who doesn't understand football and shouldn't be near the game if that is enough to put someone near the screen."
The goalkeeper was out of action for a while as he took a hit from Bowen, with Tuchel confirming Edou picked up an injury.
