Cassano feels the Scudetto will be decided by three teams.
He said, "Juve, Inter and Milan are the favourites, they are the strongest teams. Inter has strengthened, Juve likewise, Milan instead I see it perhaps less strong but more aware. It is a team that is proving to be at the top, it can fight again this year.
"(Angel) Di Maria is a phenomenon, we have not discovered him now, we have known him for 15 years even if he has always been a lot underestimated by the press. He is a player who always makes a difference, he is the strongest player in Serie A now and it is a pleasure to see him play.
"Then from what they tell me he is a fantastic person and a hard worker. If Juve rely on him, they can have great results, but he has to play better."
