The defender is beginning to find his feet at Milan this season.
"I'm fine here," he told Milan Channel. "I'm getting on really well with all my teammates. We train every day together and there has been no problems.
"I think Balotelli is very important to us. He will show his value to this team as the season goes on.
"Kaka played a great game [against Barcelona in the Champions League]. He trains at 100 per cent every day and will become even more vital as the campaign goes on.
"I think everyone can learn from his behaviour."
