"Ronaldo and Kaka are phenomena. All the players of AC Milan are phenomena," said Pato. "I am just one more player of Milan.

"As a child, I had one hero - Ronaldo. Ronie is a big hero. Now I have the chance of playing with him and I am very pleased."

Milan president Silvio Berlusconi believes Pato is a 30 goal-a-season striker, but the youngster adds: "I am only thinking about the first one.

"I just have to stay calm and play well. The goals will come."
