The 30-year-old has recently been linked with a move to Major League Soccer side LA Galaxy.
“Ronaldinho is really happy to be at Milan,” his agent and brother Roberto De Assis told Sky Italia.
“I’ve always said there is a contract. There is a good relationship with Milan and with Galliani.
“We are happy because we are in a big team and we will work for a big season.
“We spoke about a renewal six months ago. There is again work for this season and so quickly, without hurry, we will get things organised.”
