The keeper is well down the pecking order at the San Siro and thought to be surplus to requirements, but Milan have yet to make an announcement on whether he can move on.
The South American club had the keeper on loan last term and are keen to sign him again, but are waiting for Milan to clarify their position.
Corinthians vice president Antonio Roque Citadini said: "The player first has to resolve his situation with Milan and then we will restart negotiations for having him loaned again with us.
"We don't know if Milan want him for the next season or not.
"We are waiting for a definitive answer and then we will start to talk about a new contract."
