Jose Mourinho faces a nervous wait after Marouane Fellaini limped off during the first half of Belgium’s World Cup qualifier against Bosnia.
The 29-year-old was believed to be suffering from an Achilles problem ahead of the clash but was given the green light to play, however during the match he landed awkwardly on his knee and signalled to the bench.
After being treated briefly by medical staff, the midfielder was substituted in the 29th minute of the game and replaced by Leander Dendoncker. Initial tests revealed Fellaini had suffered a strain to the inside of his left knee and possible further damage to a ligament.
After the game, Belgium manager Roberto Martinez said: “We are all worried about Fellaini. We fear that there’s ligament damage.”
A Belgian FA official also confirmed the injury, and said: “It is something to be worried about on first sight. Ligaments, left knee. More news tomorrow.”
It is understood Fellaini will undergo a scan on Sunday and Manchester United will monitor the situation ahead of their trip to Anfield to face rivals Liverpool next Saturday.
Fellaini has emerged as one of United’s most trusted midfielders this season, scoring twice in his last league outing against Crystal Palace and was expected to remain in the starting XI.
It is feared Fellaini could be out of action for a few weeks which will be a severe setback for Mourinho, who has already lost his £89million signing Paul Pogba to a long term hamstring injury.
With less than ten months remaining on his contract, Mourinho had been hoping to strike a deal with Fellaini and his representatives but a conclusion had yet to be reached and now doubt has been cast over his future at Old Trafford.
Belgium’s match against Bosnia turned into a seven-goal thriller after they came from behind to win 4-3.
