Manchester United manager José Mourinho is believed to be deeply concerned over suggestions that Belgium will field their star striker Romelu Lukaku in this evening's World Cup 2018 qualification match against Cyprus.
Daily fantasy football game www.oulala.com have taken a look at how United have fared with and without the Belgian going all the way back to 2013 when he joined the club. We have not lost a league match this season, dropping points only at Stoke with Lukaku leading our charge with seven league goals already.
Belgium boss Roberto Martinez is confident Lukaku is fit enough to face Cyprus, but he has stated that the 24-year-old will be used wisely.
Jose Mourinho is certain to be livid after hearing that one of his key players will be sidelined for an extended period, which includes missing their crucial clash against Liverpool on Saturday (14 October).
He added: "It was a very unfortunate injury for Marouane Fellaini".
Premier League heavyweights Manchester United are embroiled in a crisis in midfield ahead of their mouthwatering clash against Liverpool this weekend.
"Romelu Lukaku is fit", he said. "A collision between two strong players, very committed that they want to win the ball, and unfortunately Marouane ended with a damaged ligament".
Mourinho will hope Fellaini's injury is not as bad as feared.
It seems very likely that Ander Herrera will play for Manchester United alongside Nemanja Matic at Anfield on Saturday lunchtime.
United are also without another midfielder in the form of Michael Carrick, although he too reported for training on Tuesday morning.
