Manchester United midfielder Mason Mount's recovery from a calf injury is proving problematic.
The summer signing from Chelsea has taken significantly longer than expected to come back to action.
Mount has been out since mid-November, while the club initially expected he would be back a month later.
Now he is still to join up with his teammates for full training, which hints at significant issues.
The Mail states that Mount has been working in the gym on the bike and not on the field.
Mount has played 12 times for United, providing one assist and scoring 0 goals so far.
