The Brazil international has had a troubled season in La Liga and has fallen out of favour with coach Frank Rijkaard following a loss of form.

A knee injury also appears to have brought a premature end to his campaign, prompting suggestions Ronaldinho has played his last match for Barca.

Milan have repeatedly been linked with a move for the 28-year-old with president Silvio Berlusconi admitting his club were interested in acquiring Ronaldinho.

And Galliani has now claimed a summer transfer has moved a step closer following a meeting with the player's agent and brother, Roberto de Assis.

"There is an agreement in principle with the player," Galliani told Gazzetta Dello Sport.

"Now we must reach an agreement with Barcelona."

According to Gazzetta, Ronaldinho will sign for the Rossoneri until 2012.

De Assis confirmed the player was in talks with Milan but insisted the move was not a done deal.

He said: "Basically, Ronaldinho and Milan have come to an agreement.

"Milan are a great team, Ronaldinho was impressed with his first contact with them.

"The important thing is that he will be happy. When will a deal be finalised? You have to be patient."
