Reports in Italy suggest that David Moyes will make signing Benatia his top priority at the end of the season.
The 26-year-old Moroccan international only joined Roma from Udinese in an £11m deal last summer, when he was also linked with United, Arsenal and Tottenham.
United have been linked with a host of defenders after Vidic revealed he planned to leave the Red Devils at the end of the season.
But it seems that United have returned to a player that they have been monitoring for some time in their bid to replace the formidable Serbian.
