The Argentina international was linked with a move to the Rossoneri in January, and the governing body's representative believes that it could be right for him to leave the Etihad
The controversial Argentine forward was linked with a move to the San Siro outfit in January, but negotiations ended unsuccessfully.
But, with Zlatan Ibrahimovic on the verge of a move to Paris Saint-Germain and Roberto Mancini reportedly interested in signing Robin van Persie, Riso has started talking again about a possible switch.
“Tevez to Milan? There were complicated negotiations, but certainly we can say that the Argentine has always been a dream signing for Adriano Galliani,” he told Sky Sport Italia.
“Perhaps this is the right time. I'm leaving for Manchester, but my business is related to the future of [Luca] Scapuzzi. While on a trip you can do many things however," he concluded.
Tevez has stated recently that he now feels settled at the Etihad Stadium, despite requesting a transfer after a well-publicised row with Roberto Mancini last season.
