The 18-year-old, who was part of the senior squad that took on Aberdeen in pre-season last summer, has featured on a regular basis for the club's development side.
His performances have impressed Ferguson, who recently talked up the Belgian's chances of selection for the first team. Having learnt of his manager's words, Januzaj admitted that he was eager to continue to impress.
"I always try to do my best in every game and try to get in the team. Hopefully, I can try to get in the first team in the future as well," he told Inside United.
"[Playing against Aberdeen] was a good experience. I really liked it and I hope it won't be the last time that I play with the first team. I will keep working hard to try and get into the first team. I hope to have a big career at Manchester United.
"[Ferguson] is a big coach, you can't say anything more about him as he is one of the best in the world. I don't think other team's managers come to watch the Under-18s and the reserves. It's really professional here and I really like it at United. I feel good here.
The midfielder joined United in July 2011 from Anderlecht.
