Those are pretty big things to be missing when you're a striker though, no? And if they're 'natural' it doesn't really matter how old he is does it, because you've either got natural talent or you haven't.
For me personally, he looks like he's short of a few of the skills needed to be top drawer. I agree that he doesn't appear to have that natural goalscoring instinct in terms of either movement or finishing, but if you look at the goals he's scored, too many of them are just bog standard finishes for my liking. I'm yet to see him score that goal that makes you think he's really got something - cutting inside and curling one in the top corner or taking it down on his chest and hitting a half volley from 20 yards. If you only score goals from inside the box, you need to be able to score a lot of them, and I'm yet to be convinced that he can.
