We take a look at the differences between Januzaj's full debut away at Sunderland and last night's cup match.
The talk pre-match from the Sky Sports broadcasters was all about the 18-year-old's sensational full debut against Sunderland, where he scored twice to save Manchester United from an embarrassing loss.
Although he couldn't replicate his heroics on the night and save his club from the same fate, he was still United's most promising player.
Manchester United legend Andy Cole proclaimed to be a huge fan of the young star, remarking that 'a star was born' on Adnan's full debut and there is little higher praise than that.
The 42-year-old former front man also claimed the midfielder had got better and better since his debut and that he would continue to do so in the future.
So how has his game changed and did we learn anything last night? Here's a statistical view...
First and foremost the player didn't score twice last night, but sometimes goals don't tell the whole story about how well, or mature a player has performed, so we looked at the bigger picture.
In United's 2-1 away league win:
Shots - 6
Shots on target - 3
Chances created - 0
Passes attempted - 37 (pass accuracy 86%)
Tackles - 1
Interceptions - 1
Successful dribbles - 5
In United's 2-1 away cup loss:
Shots - 7
Shots on target - 1
Chances created - 0
Passes attempted - 28 (pass accuracy 88%)
Tackles - 0
Interceptions - 0
Successful Dribbles - 3
Although the statistics don't quite match up to the ones he produced on his debut, it takes nothing away from what was still a lively performance from the United starlet.
The difference was last night, Sunderland were well aware of what he could do, and weren't caught napping. Even so he caused them plenty of problems throughout.
He looks every inch of a potential world class player and even in games like the one last night where things don't go his way, he still keeps his head up and tries to make things happen.
A very rare quality in such a young player and only the best in the world have it.
