The defender has penned a deal to 2015.
"We never talked money as my intention was to stay," the defender told Milan Channel after meeting with Vice-President Adriano Galliani. "I'm happy to still be a part of this club.
"The team is developing but ended this season well, there is a good mix of young and experienced players and it will endeavour to return to the top in Italy and Europe."
"If I had the feeling that I would only be here as a reference figure in the dressing room then I would not have stayed," he added.
"I really want to play, certainly my experience will be put to the service of these young players, but I am not satisfied and want to win so much with this shirt."
