Roberto de Assis is negotiating on behalf of the Barcelona ace and despite claims from Inter and Manchester City that they're in the frame, Milan remain favourites.
"Milan are enthusiastically involved in negotiations with Ronaldinho," he told Canal Plus. "We have made lots of steps forward, even though that doesn't mean that the deal is done.
"As long as Dinho is under contract with Barcelona, we cannot say anything for certain. But Milan are in the strongest position to sign him."
