Because he's done some things that shows that he clearly has natural talent, even though he's been very inconsistent so far because of low confidence. When you are low on confidence you think too much and start thinking "what if i miss this pass", you don handle or strike the ball with the same authority.
I've seen him in play in france as well. No doubt that he has ability. Just needs to fully adapt and find som confidence.
He's low on confidence and when you are that it's natural that you take too much time on the ball and especially decisions. You can clearly see that he has technical ability and is a better passer of the ball than he has shown. When you are confident you don't think much and everything just works without much thought.
I'm sure that once he gets a goal his confidence will make a massive difference to his game overall. Just a matter of time until he's fully adapted and starts performing to the level he is capable of.
