Chelsea were desperately poor once again against Norwich City on Wednesday night, yet it wasn't the players that Antonio Conte was so angry with at the end of extra time.
As penalties loomed, Conte was pictured in a heated debate with referee Graham Scott, who had denied Chelsea a penalty when Willian was brought down by Timm Klose in the box.
Scott booked Willian for diving and despite replays clearly showing there was contac, not even the video assistant referee (VAR) said it was a penalty.
Mike Jones, who was watching the footage behind the scenes, decided there wasn't a clear and obvious foul, so the incident wasn't reviewed at length.
"If we want to use a new system, I can't accept a big mistake," said a frustrated Conte. "In this case, the Willian penalty was a big, big mistake.
"Not from the referee on the pitch, who took quickly a decision to book Willian and didn't have any doubt, but from the person watching the game (Jones).
"I hope the VAR wasn't a referee because if you see that watching on television and don't think that's a penalty... he has to improve. It was very clear.
"At least to avoid a big mistake, call the referee and tell him: 'Look, maybe this situation there is a doubt. For me it's no penalty, but it's better you go and watch it, and then take the final decision'.
"We need to improve if we want to use this new system. We have to wait to check with the person who is watching the game and then, if this person is sure 100% that it is simulation, go and book Willian."
WILLIAN'S PENALTY SHOUT
Check out Willian's supposed 'dive' in the video above.
Instead of reviewing the footage at length like he should, Jones made the call that Willian dived and there wasn't enough contact. It was based on his own opinion.
And this infuriated Alan Shearer. Speaking on the BBC, the former striker absolutely nailed his reaction to VAR not overturning the decision by labelling the system as a "shambles".
Here's the conversation between Gary Lineker and Shearer.
LINEKER: "The referee decided it was a dive, it went to VAR, they looked at it, they backed the referee up."
SHEARER: "You're seeing why I was very doubtful about it and now it's a shambles. We all think that's a clear and obvious penalty - and he even books him.
"Who on earth is looking at that screen in Stockley Park and doesn't think that's a penalty? That's why it's all wrong because it's someone else's opinion. It's a shambles."
Well said, Alan. At the very least, Jones should have contacted Scott and told him to review the incident himself on a screen, rather than make his own call.
