He has recently lost his place in Milan's starting XI, but appears committed to winning it back.
Speaking on his return from international duty, Ronaldinho said: “There are many players [at Milan] whose contracts are up, but I am calm and happy here.
“I don't want for anything and I am calm about the contract.
“I am happy to have got back to playing [with Brazil] even if it didn't go how we wanted against Argentina.
“I have not been playing a lot recently. I lack the right rhythm, but now I want to keep playing well with Milan so I can be called up to the Brazil squad again.
“I am also ready to play as a striker for Milan. It's down to what the mister decides. I hope to play against Fiorentina.”
