The 18-year-old midfielder has taken the Premier League by storm after making his debut for the club at the start of the season and is keen to win trophies with the Red Devils
The 18-year-old only made his first-team debut at the start of the current campaign but has gone on to make 17 appearances in the Premier League, cementing his status as a key member of David Moyes' squad in the process.
And after such an impressive start to his United career, Januzaj insists he wants to become the club's most important player, outlining his desire to win trophies at Old Trafford.
"I am quite pleased with my year, I have done a lot of work and have been integrating into the first team," he told the club's official website.
"I have played games and I think there is more to come. I hope to win trophies at this club and be the best player."
When asked his views on record signing Juan Mata, Januzaj admitted he was hoping to learn a great deal from the former Chelsea playmaker.
He added: "He is a great player and I think I am going to learn a lot from him.
"He is a technical player who is very clever. He scores goals and gives assists. We are very happy to have Mata at the club."
