Marouane Fellaini will reportedly be out of action for up to a month with a calf injury.
The Manchester United midfielder has only played 31 minutes for United under caretaker manager Ole Gunnar Solskjaer but was absent from the squad that went to Tottenham last week.

The 31-year-old was in training with teammates on Wednesday but is expected to miss the FA Cup fourth-round tie at Arsenal next week, including the Champions League round-of-16 first leg showdown with Paris Saint-Germain at Old Trafford on February 12.
“There are not many issues,” Solskjaer said of United's squad situation, “I think just small niggles, as there always is at this point of the season.
“Chris [Smalling], Marcos [Rojo] just started running lightly, so not fit yet. Alexis [Sanchez] has trained all week, so hopefully, he'll be available.
“And Felli is the long-term one that's out. He'll be out for a few weeks. He'll probably be at least three or four weeks. He's got a calf problem and that's sad.
“There's X-factors in different players and we all know Felli's X-factor and then again he'll be working hard to get back in when all the big games are coming as well.”
