The 18-year old had already made waves in his first start for the club in October 2013 against Sunderland, where he scored a brace to carry United to a 2-1 victory at the KC Stadium.
The Belgian, who had his start at FC Brussels in 2005, has filled the role as a left winger since he started playing regularly in the first team under David Moyes.
The Scotsman however believes that Januzaj’s true calling will be in a central role for the Red Devils, wearing United’s No. 10 shirt.
“In time, Adnan’s best position will be No.10,” Moyes told reporters.
“But while he’s so young, it is better to introduce him on the left or right.
“He’s a terrific centre-forward as well and so talented that he can play in several positions. The boy’s working really well and, whatever job we give him, he’s so talented that he can handle it.”
Adnan Januzaj had recently signed a new five-year contract with Manchester United, and Moyes insists that the Belgian will not be overplayed this season.
The Scottish boss compared him to Wayne Rooney’s emergence as a first team footballer at Everton as a 16-year old and states that he won’t be over pressuring the young footballer, allowing him the time to grow and mature at United.
“I don’t want to put too much expectation on the boy, which is why I’ll take him out so he doesn’t tire,” said Moyes.
“But he’s got something which I haven’t seen for a long time.
“I’m trying to keep the reins on him. It is a bit like I had with Wayne when he was a young player.
“I remember I used to get a bit of criticism because we played Wayne on the left a couple of times.
“You can’t always get the young players right in and when you do, you try to find the right slots for them.
“It didn’t do Rooney any harm!”
