Robinho was on the scoresheet in Milan's victory over Napoli on Monday.
"When will you see the real Robinho? I hope as soon as possible. I am in better shape physically and I'm happy. The team is doing well and so am I," he told Sky Sport Italia.
"Serie A is difficult and wonderful; I enjoy it and hope to remain for many years. Milan are a great side and we have the opportunity to win this season. It's also good to play where many Brazilians have found success.
"We respect all the teams in the Scudetto race, but if Milan do well, then we can win everything.
"We know that we are the strongest and that if we do our work, our side will come out on top."
