AC Milan boss Gennaro Gattuso was furious after defeat to Inter Milan on Sunday.
Gattuso admits seeing his players clashing on the bench angered him.
Franck Kessie squared up to Lucas Biglia after being substituted and had to be held back by teammates.
Gattuso said, “There has to be respect for everyone in the dressing room and it was just unacceptable. I am the Coach, I have to take care of discipline in the dressing room and the players know how much I care about that.
“You can criticise my tactics, but I built my career on respect, group ethics, representing the jersey, honouring the teammates who haven't played for months. This means the world to me and that is why it is a double defeat.
“I will have my say over the next few days."
