Milan win against Red Star Belgrade. but, Davide Calabria was visibly upset
As reported by La Gazzetta dello Sport in this morning's print edition, team captain Davide Calabria was furious after being substituted.
The full-back left the pitch without acknowledging the coach and headed straight to the locker room.

It's likely that Paulo Fonseca's post-match outburst also pertains to this incident.
What did Fonseca say?
"I am not the kind of person who is satisfied with just the result," he told Sky Sport Italia. "Of course, the most important thing is that we won and are in a good position, but that's how I am. There are difficult things to change, and sometimes I get tired of fighting against them. I am not satisfied with the team's performance."
