Pato is currently in Brazil on international duty with his new club teammate Robinho.
He said: "Robinho is asking me everything about Milan. We get along perfectly on the field, as he knows the right movements and can also hide the ball from his opponents.
"Clearly I am also happy that Dinho has stayed with us, as he is truly great. I think that, aside from the forwards, to win something important this season we'll need the 'goals' in defence from Alessandro Nesta and Thiago Silva."
