PSG pair Neymar and Edinson Cavani had to be pulled apart inside the locker room after victory over Lyon.
The fallout of their free-kick row is still being felt, with L'Equipe reporting the attacking duo took their argument into the dressing room after the game.
PSG captain Thiago Silva had to get into the middle of the warring pair to prevent a full blown fight.
The clash has now split the squad, with PSG's Brazilians siding with former Barcelona star Neymar, while Cavani retains the respect of his teammates because of the length of time he's been with the club.
Despite reports of the brawl, PSG president Nasser Al-Khelaifi accused the press of stoking things: "There is nothing.
"You, the media, are the ones that cause the problems."
