Former AC Milan coach Arrigo Sacchi says fans must be patient over their current crisis.
Sacchi feels recent protests from ultras is out of order.
"Because of 25 years of success, is it right that the fans challenge the club and threaten the team? It is a serious matter," Sacchi has reflected on Radio Anch'Io Sport.
"There is a lack of appreciation, a lack of respect towards the players. The violence has once again prevailed and in that environment it is difficult to grow. I would like greater support.
"You cannot always be on top, there are times when you go wrong and others are better than you, you must know how to accept that. In our football we lack civilisation.
"The choice of the right people is key, then return to a focused style of play and go and find the most suitable interpreters. Functionality first, then talent."
