3) Adnan Januzaj
Brought into the first-team by David Moyes last season, Adnan Januzaj instantly looked like one of the most promising young players in the game. However, the Belgian has stalled this season after being given limited playing time by van Gaal, and rumours have already surfaced that he could be loaned out or even sold before long. One thing’s for sure, young players need regular playing time and confidence instilled in them, and this is once again a case of some poor handling from van Gaal, who has made Januzaj into something of an outcast at the club for no obvious reason.
