Stefano Pioli responded angrily to refereeing decisions following Milan's elimination from the Coppa Italia after a 3-0 loss to arch-rivals Inter on Tuesday.
Pioli abruptly walked out of his post-match interview with Mediaset after reviewing footage of a disallowed goal for Ismael Bennacer where Pierre Kalulu was ruled offside for obstructing Samir Handanovic's view in the Inter goal.
With Milan 2-0 down in the 68th minute of the second leg of the semi-final clash, Bennacer's goal would have been timely and provided them with critical late momentum.
After seeing the replay, the 56-year-old Rossoneri boss could not hide his frustration.
"Look at Handanovic's reaction, if he protests," Pioli told Mediaset. "He doesn't do anything, if a Milan player had blocked his view he would have immediately run to protest. Come on, now."
Milan were marginally second best for the majority of a tightly fought match and Lautaro Martinez's first-half double was ultimately reflective of the game's complexion to that point.
Regardless of how much the disallowed goal could have influenced proceedings, Pioli conceded Inter were the better side.
"We wanted to win, we didn't succeed. We came up against a strong opponent," Pioli said. "The result is clear, but I don't think it was like there was a big difference and Inter scored at the right moments.
"We continued to play and create, 2-1 would have given us the possibility because we were playing. After that, everything became more difficult.
"Of course we can do more. When you concede three goals it means that others played with more quality. It was not our evening. It's too bad because we wanted to reach the final at all costs."
