Manchester United and manager Jose Mourinho now face the prospect of being without the in-form Paul Pogba until late October.
Having experienced a mixed season last term following his much-publicised world record transfer from Juventus, the 24-year-old has begun the new campaign in fine form, with two goals and two assists already to his name.
Against Basel in the Champions League on Tuesday night, the sight of a distressed looking Pogba, sitting on the ground in the rain, immediately sent chills of dread through United fans.
Replaced before the 20-minute mark with a suspected hamstring injury, it was initially feared the Frenchman could be out of action for up to a month, according to the Express.
Now, as the medical team at Old Trafford learn more about the injury, BBC Sport is claiming the pivotal midfielder could be out of action for anything up to six weeks.
Such a layoff would be a blow to United as they face into a schedule that includes eight fixtures before a potential return in late October.
With clashes against the likes of Everton, Liverpool, CSKA Moscow and Benfica in that time, Mourinho could well be set for some selection headaches during this crucial period.
The United faithful will now be hoping that the in-form attacking midfielder will do a ‘Zlatan’ and recover quickly so he can help keep United in the impressive form they have shown so far this term.
