Donadoni was a Milan legend and was asked about the Curva Sud protest against the team.
"It's disappointing, but clearly when a side like Milan is in this position in the table, you can expect some protests.
"I think in any case Milan came out eager to fight hard and turn around a complicated situation. With 10 men they came back from 2-0 down, so that must mean something.
"I believe the fans ought to help the team get back on its feet. I realise that's not easy, but calm is the only way to go forward."
