Ronaldinho's brother and agent says the Brazilian playmaker is still keen to join Milan, although a decision on his future may not be taken until after the Olympic Games.
The 28-year-old could leave Barcelona before the close of the transfer window after new coach Pep Guardiola suggested he would not stand in Ronaldinho's way.
Manchester City have prepared a lucrative offer for Ronaldinho, while Chelsea have been linked with a bid following Luiz Felipe Scolari's appointment as manager.
Milan have held a long-term interest in the forward, although vice-president Adriano Galliani admitted last week the Italian giants are unable to compete with City's offer.
However, Ronaldinho's agent Roberto De Assis is not giving up on the possibility of securing his brother a move to the San Siro this summer, despite Milan making Emmanuel Adebayor their top target.
"We are working to take the best player in the world to the greatest club in the world," De Assis told the Italian media.
"We have always had an excellent rapport with Milan and are in constant contact.
"The chances of Ronaldinho playing with a Rossoneri jersey this coming season remain the same as they were a few months ago."
Reports in Spain, though, claim that Ronaldinho could yet stay at Barcelona to fulfil his contract at Camp Nou, which runs until 2010.
There are also suggestions that the former Paris Saint Germain ace, who is also wanted by Palmeiras, Internacional and Boca Juniors, will wait until he has played for Brazil in the Olympic Games in August before finalising his future.
