Ronaldinho's agent and brother claims Blackburn Rovers have been in contact with him - and says there is "other interest in England".
AC Milan announced last week that they are willing to sell the former European Footballer of the Year for eight millions euros (£6.8m).
The Brazil playmaker has six months remaining of his contract at the San Siro but Milan are willing to sell this month if the price is right.
Quoted in the Daily Mirror, Ronaldinho's agent and brother Roberto de Assis said: "Blackburn have contacted us. There is also other interest in England but this is confidential."
Brazilian side Gremio also appear keen to sign the 30-year-old, although they were initially thought to be confident of securing their former player on a free transfer which no longer seems to be the case.
De Assis added: "We will arrive in Porto Alegre in order to negotiate with Gremio, but nothing is decided.
"If we do not reach an agreement with a a club in Brazil then he will return to Milan as he is still a Milan player. We are not ruling anything out."
