Manchester United winger Adnan Januzaj has reportedly suffered another injury setback ahead of Sunday 10 April's Premier League clash with Tottenham Hotspur. Januzaj, 21, returned to Old Trafford following a loan spell at Borussia Dortmund during the January transfer window but has found his first-team opportunities severely limited.

Since returning to the club, the Belgium international has featured more frequently for the Under-21 ranks and has played just 14 minutes of first-team football. While playing for Warren Joyce's reserve side in February, Januzaj picked up a hamstring injury that hampered his hopes of returning to the first-team fold.

Belgian news outlet DH reports the youngster is now struggling with another hamstring problem that forced him to withdraw from an Under-21 clash with Chelsea on Monday 4 April, having featured in the last three matches for the side.

While injuries have proven to be a stumbling block in securing more first-team chances, Januzaj's attitude has also reportedly been questioned by those at Old Trafford, including manager Louis van Gaal.

According to the Daily Mail, his exile from first-team duties is a result of excessive showboating in an Under-21s match against Sunderland in January. Januzaj and Andreas Pereira, another to have struggled to force his way into the manager's plans, both attempted to score directly from corner kicks during that match, with word of their antics eventually reaching van Gaal who was far from impressed.

It is not the first time Januzaj's attitude has been questioned. Following the player's return to United in January, Borussia Dortmund manager Thomas Tuchel explained the winger struggled at Bundesliga club because "a part of him was always still in Manchester".

Prior to that, the youngster was also heavily criticised for his "poor attitude" by Belgium Under-21 boss Enzo Scifo when the player turned down a call to represent his side in November.
