Mario Balotelli signed with Serie B side AC Monza, the team announced on Saturday.
The club are co-owned by Silvio Berlusconi and Adriano Galliani.
The 30-year-old has been a free agent since parting ways with Brescia last summer.
AC Monza are currently ninth on the Serie B table.
Italy manager Roberto Mancini has kept the door open for Balotelli's potential return to the national team.
