^Yes it was weird, it's as if his bulk (being top heavy now) has affected his mobility a bit and/or he hasn't got match sharpness yet.
Once he finds that, I think we'll see the much more incisive Januzaj that we all love. The decision making may still take longer than that but even today he showed lovely bits of skill, ball control, body feints etc. Lovely to watch on the eye of course and depending on your view, maybe perhaps ineffective but those are signs of a really classy player. If he gets the opportunities to display those in a more fluid Utd team, who knows, he might start show more than just potential.
Please give him regular game time LVG. He is showing improvement, let's nurture it whilst his fire is still strong. Not getting playing time even for a young and mature player like him must be mentally cumbersome.
