Liverpool boss Jurgen Klopp hit out at Jose Callejon after their Champions League defeat to Napoli.
Klopp was angry that the Italians were awarded a penalty in the 82nd minute.
He fumed: “That was the game-changer tonight.
“I'm sorry, but when the player jumps before there is contact then it can not be a penalty. I can say a lot of things about it, but then it would look like a bad loser.
“When you see it again, you can see it is a clear mistake. But then human beings are the ones who decide if there is a mistake - and with VAR as long as human beings decide, then there is a potential for failure.
“But we can not do anything about it now. We have to accept it. They will find a reason to say it was the right decision, and we have to accept it."
