David Moyes has said that Adnan Januzaj has been rested in recent weeks because he has played "an incredible amount of games" with Manchester United this season.
The 19-year-old has scored three goals in his 29 appearances for the team this season, but has played just twice so far in March.
Ahead of this weekend's game against Aston Villa, the manager told reporters: "I think Adnan has played an incredible amount of games for an 19-year-old. We have to be mindful of that. We have seen signs in training that we have to be careful what we do with him.
"He is a great talent and he is someone we know will go a long way at Manchester United. But we are just being careful with him. We have to do the right things and he has played a lot of football."
United have lost two of their last three matches in the Premier League.
