The veteran shot stopper spent three and a half years with the Rossoneri before joining Juventus, but returns to San Siro to offer depth in goal
AC Milan have completed the signing of veteran goalkeeper Marco Storari from Cagliari on a contract until the end of the season.

The 40-year-old Storari previously enjoyed a spell with Milan between January 2007 and June 2010, making 13 appearances in all competitions.
