The Italy skipper said: “Ronaldo is still a phenomenon. I think Milan have completed an excellent deal.
“He remains the strongest player around. I have played against him and he has always managed to impress me.
“I have heard other players say this, but Ronaldo is the only footballer who ever gave me the impression that I was facing someone who was really different from all the rest – like Diego Armando Maradona.
“Ronaldo had some misunderstandings with the Coach and some problems because of injuries, but that is part of the game.
“Now he has taken a different road and I hope he will do well.”
