Marouane Fellaini has a wrist injury and will miss several weeks of action for club and country.
The Belgian midfielder missed United's 2-1 win against Sunderland, and David Moyes later confirmed that he would see a specialist on Monday. But news has come out that Fellaini is set to miss several weeks of action, which will be a blow to United.
The international break means this will be negated somewhat as United have fewer games in the period, but it's still a big blow, especially since it hampers his chances of settling in and nailing down his place - Shinji Kagawa was also injured for a few weeks early last season, and we all know how that turned out.
The good news for United is the club have four winnable home games over the rest of the month: Southampton in the league, Real Sociedad in Europe, then Stoke in the league and Norwich in the League Cup. He could, however, also miss the away game against Sociedad, as well as a vital home game against Arsenal afterwards.
