Napoli legend Careca believes AC Milan striker Alexandre Pato will become the world's best player.

Pato has been likened to Careca and the former Brazil international said: "Pato will become the best footballer in the world. He has a very bright future.

"Recently, Carlo Ancelotti has compared him to me, and I agree with this judgement and I am especially proud because Ancelotti was a very good football player and knows what he is talking about.

"Pato is very fast, can decide what to do in a fraction of a second and has good finishing ability. He also has a great desire to win."

Juventus coach Claudio Ranieri also said: ''There are extraterrestrials and Pato is one for what he did see yesterday at the San Siro. He played like a 30 year-old, with personality."
