AC Milan superstar Ronaldinho insists that he is unaffected by compatriot Kaka's departure from the San Siro.

Speaking to Corriere dello Sport, he said: "Kaka's departure does not affect me personally.

"He is no longer with us, but my responsibilities within the team do not change."

Milan chief Silvio Berlusconi believes that Ronaldinho will have a greater role to play in the upcoming season.

Under new coach Leonardo, the Brazilian ace will look to improve on last season's performance following a dismal start with the Italian giants.

"My objective is to win with Milan. We want to conquer the Champions League.

"On a personal level, by playing a great season I can win back my place in the Selecao and be a protagonist at the World Cup," he added.

Ronaldinho made 29 appearances and scored eight goals for Milan since he joined in 2008 from Barcelona.
