Januzaj is aware of the impact that stepping up to first-team level is having on his game but is continuing to learn all the time.
"Everything is quicker," he stressed. "The games are quicker, you have to think faster and play quicker. I'm training with great players almost every day so I do what they tell me but at the same time I want to bring my own qualities too. That's important. You have to do both.
"The technical qualities [of the likes of Robin van Persie, Shinji Kagawa and Wayne Rooney] are brilliant, so just playing alongside them raises your standards. You learn little things like when to speed up play, when to pass, when to hold the ball, all those things... by watching experienced players it just becomes natural."
