Adriano left Inter six months ago after going AWOL while on international duty in Brazil.
Adriano is currently playing for Flamengo, but reports suggest he is struggling to maintain his training schedule with the club.
“There was talk of Milan even when he was still at Inter, so perhaps in the future he could join them,” agent Gilmar Rinaldi told Telelombardia.
“The contract has no clause stopping him from going to the Rossoneri.”
