Cavani's infamous bust-up with Neymar over a disputed penalty almost saw El Matador driven out of the club.
The Uruguay international recalled: "I think the responsibility goes to Unai Emery. The shooter should always be defined before the match.
"I said to Ney, 'Ney, I'm shooting'. But hey, we returned embarrassed to the locker room. I told him what I thought.
"Everything ended up in the hands of Unai and he decided that the shooter would be Neymar."
