The veteran centre-half missed the FA Cup defeat at Liverpool with a back injury but the Old Trafford boss remains hopeful Ferdinand will be available for the Premier League tie with the Potters.

Nani, Wayne Rooney and Phil Jones also missed the FA Cup defeat, with all three struggling with ankle knocks, and it remains to be seen whether the trio will be available for Stoke's visit.
