Sir Alex Ferguson has confirmed Tom Cleverley is a doubt for Sunday's Manchester derby after limping out of United's 1-0 Champions League defeat to Cluj with a calf injury.
The midfielder was forced out of the game just before half-time and Ferguson is not expecting a positive outcome from his assessment on Thursday.
"Tom felt his calf a little bit. We will assess it in the morning (on Thursday) but it is not good news," said Ferguson.
