Manchester United may be without defensive duo Chris Smalling and Jonny Evans for their crunch Champions League match with Olympiakos.
Smalling (hamstring) and Evans (calf) both missed training on a wet morning at the AON Training Complex in Carrington as David Moyes ran the rule over his players.
United head into Wednesday's Sky Live clash trailing the Greek side 2-0 from the first leg and licking their wounds following Sunday's embarrassing 3-0 home defeat to bitter rivals Liverpool.
It is understood that Moyes retains the backing of the United board despite rumours that the club are considering a replacement.
Moyes has a huge task ahead of him if he is to finish in the top four of the Barclays Premier League. United are seventh in the table, some 12 points behind the Champions League qualification places with nine matches left.
The United manager has an equally difficult task ahead of him if he is to overturn the two-goal deficit at Old Trafford on Wednesday and qualify for the quarter-finals of the competition.
