Manchester United could be missing four key players ahead of the Premier League meeting against Chelsea on Sunday.
The Red Devils are currently second in the league standings with 49 points, six ahead of the Blues, who are occupying the fifth place.
They are in a healthy position to qualify for the Champions League next term but can’t afford any complacency with 13 games left in the season.
Meanwhile, the Norwegian added that Daniel James is a doubt with a knock sustained in the Europa League and he is unsure over his availability.
United are the only side in Europe’s top-five leagues without an away defeat this term and they will be hoping to preserve the record with a victory at Stamford Bridge.
