He is only seventeen. Sure I agree he won't be as good as them but give him more physical tools and confidence, I think he will be dribbling just fine.
He won't. Things like dribbling ability are apparent at this age. I haven't seen his youth videos, but if he's similar there as he is here he will barely improve. It's not a big deal, we still have Dembele/Trincao on the right side to take care of take ons and runs with the ball. Makes for a balanced wing set up.
