The Manchester United youngster says he is struggling to establish himself as a fit under the current tactics.
The highly rated Belgian was a star performer as former manager David Moyes struggled at Old Trafford last year, but has so far failed to establish himself in Louis Van Gaal’s system.
That style sees United employing full backs rather than wingers, a system that currently has no place for Januzaj, who made just his first start since November in the 3-1 win over Leicester City on Saturday.
Now, the midfielder has admitted that he has found it hard to force his way into Van Gaal’s plans this season because of how their tactics have changed since he took charge in the summer.
“Yes, the system can make it more difficult for me to play there,” he said.
"I'm not really a wing-back. It's harder for me because there is more defending involved and I'm not really a defender."
However, he says that he will continue to keep working and fight for a place in the starting eleven because he wants more games this season. Despite that, he insists that his favourite position is in the number 10 role or as a winger, which may limit his playing time like he has already said.
“I have to keep working That is what I am doing in training every day, as I want to get more games this season,” he added.
“My favourite position is as a No.10 or a winger. There are lots of players here and I can play in different roles - it's just a case of taking my opportunities."
