Manchester United midfielder Marouane Fellaini sustained a knee injury while on international duty for Belgium in a World Cup qualifier match against Bosnia-Herzegovinaon on Saturday. The injury has deepened the club’s injury concerns ahead of an important encounter against Liverpool in Premier League.

Fellow Man U player Romelu Lukaku was rested by the side for the match after picking up an ankle injury. The club’s manager José Mourinho had already expressed concern that an international break could break the team’s momentum before the crucial match, and will be quite unhappy with his worst fears coming true.

Belgium manager Roberto Martinez hinted that Fellaini’s injury is serious and could force him to remain off-field for a long time. “We are all worried about Fellaini. We fear that there’s ligament damage,” Martinez said post match. 29-year-old Fellaini will undergo an MRI on Sunday, the Belgian FA informed. “It is something to be worried about on first sight. Ligaments left knee. More news tomorrow,” it said.
