A furious row erupted following AC Milan's 1-0 win against Lazio on Saturday evening.
Milan, who were hosting the game, won 1-0 via a Franck Kessie penalty in the 79th minute.
The victory, which came following six minutes of injury time, is a vital one for Milan's chances of playing Champions League football next season. Currently, there are six teams vying for the third and fourth placed spots in Serie A with eight points separating them.
Players and staff from both sides were involved in the row.
Milan manager Gennaro Gattuso said after the game that his attitude to such situations has changed since his playing days.
"I even gave myself a thigh strain running over to calm everyone down," Gattuso told DAZN.
"I was on the bench, I saw some words were flying between the sets of players. The important thing is that it ends there.
"When I was a player, this sort of thing fired me up, but now I see it with different eyes and am too old for that.
"Plus, if I launch a slap, I'm very likely to get one back and they've all been to the gym more than me."

Milan players Tiemoue Bakayoko and Kessie caused further controversy after the game when they celebrated with the shirt of Lazo defender Francesco Acerbi.
Bakayoko and Acerbi had been involved in a social media back-and-forth in the build-up to the match. In an attempt to end it, Acerbi had swapped shirts with Bakayoko after the final whistle.
Bakayoko and Kessie later apologised for their actions.
