Manchester United manager Jose Mourinho suggested that Paul Pogba's hamstring injury will rule him out for the long term though no specific timescale was given.
The 24-year-old playmaker came off injured just 19 minutes into United's UEFA Champions League victory over Basel, and he has subsequently missed the previous four matches for the Europa League holders.
It was initially estimated that Pogba would be out injured for around a month to six weeks following the strain he picked up on 12 September against the Swiss outfit.
Nonetheless, Mourinho would not specify just how long his star central midfielder would be on the sidelines for the Red Devils. The 54-year-old told reporters, "I don't speak about long-term injuries."
However, he was more positive on the fitness of injured defenders Phil Jones and Antonio Valencia, adding, "I cannot have hope, like with Jones or Valencia who I can see in training, and hope for a positive answer (on Pogba)."
Meanwhile, central midfielders Michael Carrick and Marouane Fellaini are also set to miss out on Saturday's Premier League clash with struggling Crystal Palace due to knocks.
