AC Milan defender Davide Calabria is convinced Rafael Leao has another level to reach.

Calabria says Leao needs to believe more in himself.

“If he becomes more aware of just how talented he is, then he can become the best in the world. I think he can win the Ballon d'Or," said Calabria.

“In terms of technique and physical characteristics, I don't see many like him."

He also said on Radio Serie A: “It is still early to talk about Inter getting their second star in the derby.

“There are a lot of matches to play before then and we will do everything to win them all, so that won't happen."
