But former Milan coach Ancelotti said: "Milan are going through a very difficult and delicate moment and I hope they can solve these problems quickly.

"I could compare him to Cristiano Ronaldo as there are players who belong to a different category than other colleagues, even among directors there are those who stand out over others."
