AC Milan president Silvio Berlusconi missed their 4-1 demolition of Sampdoria.
M'Baye Niang struck twice in the 4-1 win.
Berlusconi was expected to be in the stands, but did not attend.
“I spoke to Berlusconi yesterday and told him not to go into the wrong locker room after the game. In the end he didn't come. There will be other opportunities," said coach Sinisa Mihajlovic.
