Ronaldinho's brother and agent claims it is '90 per cent' likely that the Barcelona star will join Milan.
The Brazilian will be allowed to leave the Camp Nou for the right price this summer and has been linked with a move to the Premier League.
Manchester City have confirmed an interest in signing the 28-year-old, while Ronaldinho has admitted he would be tempted to work with Luiz Felipe Scolari at Chelsea.
However, Milan have long been favourites to sign the playmaker, despite vice-president Adriano Galliani stating the club would not break the bank for Ronaldinho.
The player's representative Roberto de Assis now appears to be confident that Ronaldinho will move to the San Siro this summer.
"It's true, he is likely to go to Milan," De Assis told Telelombardia.
"Everything is ready for the transfer. It is 90% and we are heading in this direction."
Los Angeles Galaxy had also been linked with a big-money offer to tempt Ronaldinho to Major League Soccer, but De Assis insists his brother will not join David Beckham in the United States.
He added: "He will never play there. He will play a tournament in Houston for his sponsor, but a transfer to the USA is excluded."
