The problems are mounting for Man Utd head coach Ruben Amorim after Bruno Fernandes was forced off at half-time during Sunday's loss at Villa Park.
Amorim confirmed today that the midfielder suffered a soft-tissue injury and is expected to miss several games.
This latest blow comes at a time when United are already missing seven senior players through injury, suspension, and international duty.
The lack of depth was evident as United finished the game with a makeshift midfield pairing of Lisandro Martinez and teenager Jack Fletcher.
Amorim insisted the club will not "panic buy" in January, but the loss of their primary playmaker leaves the squad looking increasingly thin.
