The attacking midfielder, who returned to San Siro this summer after four years at Real Madrid, will be out of action for up to four weeks due to a hamstring problem and the Italian is determined to give his team-mate something to cheer in their Champions League opener.
"I send my best wishes to Kaka. He's a great player and extremely important for our team," the attacker told a press conference.

Matri last met Celtic with Juventus in last year's edition of the Champions League, when he netted twice in the Serie A champions' 5-0 aggregate win in the round of 16, and the Italian is keen to see history repeated.
"I have a good history with Celtic. I hope history repeats itself and we get the three points," he added.
"They're a strong team that have been playing together for a long time. We'll have to play our own game and, with the help of the fans, we want to get started in the best way we can."
