Sulley Muntari has joined Milan on loan from city rivals Inter, the Rossoneri have confirmed on Tuesday afternoon.
The 27-year-old Ghana international was expected to switch San Siro sides at the end of the season, but the move has been brought forward.
The midfielder, who spent part of last season on loan at Sunderland, joined Inter in 2008 from Portsmouth.
Muntari has also played for Udinese in Italy.
