AC Milan strengthened their grip on fourth place in Serie A with a tense 1-0 win over Lazio at San Siro on Saturday that ended with a scuffle breaking out between players from both sides.
Gennaro Gattuso's side knew they had to win to remain in the final Champions League qualification spot after AS Roma had defeated Udinese 1-0 earlier in the day.
Franck Kessie's penalty 10 minutes from time secured a vital three points for Milan against one of their rivals in the race for a top-four finish, extending their lead over Lazio to six points. However, Lazio have a game in hand.
Tensions spilled over after the final whistle as a melee broke out between the two sets of players who will face off again at the San Siro on April 24 in the second leg of the Coppa Italia semi-final. The first leg ended goalless in Rome.
"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 are fourth on 55 points, two behind third-placed Inter Milan, who play at Frosinone on Sunday.
Fifth-placed Roma are just one point behind Milan, while Atalanta (52) and Torino (49) still have to play in this round of matches.
"We already showed a week ago that we're picking ourselves up from an ugly period and today we battled, we did well to have courage and create problems," Gattuso added.
"Lazio are always a tough team to face, they are a physical, fast and technical team.
"Compliments to the guys, now we must rediscover consistency. I only ask my players to fight for the shirt, not for me, it is the history of the club that will endure."
Ciro Immobile threatened for Lazio early on as his low shot drew an agile save from Pepe Reina and the Italy striker came close again just before halftime when his angled finish came back off the outside of the post.
With just over 10 minutes remaining, referee Gianluca Rocchi awarded Milan a penalty for handball, only for the decision to be overturned following a video assistant referee (VAR) review.
However, only a minute later Rocchi again pointed to the spot when Lazio substitute Riza Durmisi barged into Mateo Musacchio inside the area, and Kessie stepped up to send the goalkeeper the wrong way from 12 yards.
