Herrera was taken off against Watford with a hamstring problem and Louis van Gaal was concerned that he wouldn’t be fit enough to play, so it’s certainly a concern he isn’t in training.
As for Schweinsteiger’s absence, that is unexpected and a real worry because if Schweinsteiger, Herrera and Michael Carrick are all out injured, then van Gaal faces a selection headache in midfield.

On the positive side, having both Rooney and Martial back in training is a real boost, mainly the latter as 19-year-old Martial has become our centre-piece in attack since he joined from AS Monaco in the summer.
Of course, absence from training doesn’t necessarily mean players are injured but it isn’t usually a good sign. We’ll have confirmation on their fitness from van Gaal during his press conference on Tuesday afternoon at 15.30GMT.
