Chelsea boss Antonio Conte had some altercations with the central referee Graham Scott and fourth official after seeing two of his players get red in extra time.

Conte was asked about the referee’s game at the end of the mach, as he answered: “I don’t like to speak about the referee and accept his decision. If we want to use a new system I can’t accept a big mistake.

“Willian was a big, big mistake. Not just the referee, but the person watching it as well.

“I don’t like to speak about the referee and accept his decision. If we want to use a new system I can’t accept a big mistake. Willian was a big, big mistake. Not just the referee, but the person watching it as well.”

On the referee’s decision to give Willian a yellow card for diving, which was later rescinded, Conte said: “I think it was very clear. It was a big mistake but I don’t want to know why, but at least to avoid a big mistake you have to call the referee and say ‘look, maybe it might be better if you go to watch’. Otherwise in this way we cut the power to the referee on the pitch. He has to make the final decision. Not another person.”
