I expect him to not shirk out of tackles every now and then, I expect him to use his physicality more (because when he does, he's a beast), I expect him to use the ball more intelligently at times, I expect him to not got caught on his heels (which happens a fair bit) i expect him to cut out the sloppy passes, and I expect some of his decision making to be better.
Granted he's young, and stuff like decision making will come with age, but some of it - like his anticipation and his use of the ball - to be a lot better then it is.
