I know what you mean about it's he good or is he lucky.
What I would say is I think you do him a deservice suggesting he doesn't need to be as clinical because he creates more chances with his pace.
He exceeds his xg regularly and finished chances that are easier to miss regularly.
His 1 on 1's always look dodgy to me though.
He has some flaws in his technique, that's for sure and they may or may not be ironed out.
When you do FA courses, they ask you to look at the 4 quadrants when looking at players, not just how 'skillful' is he.
Technical / Tactical - He's probably a 7 here, he has good movement and knowledge to know where to be and when to be there, that shows a top tactical awareness, on a technical perspective, his first touch technique isn't the best, and he can appear clumsy with his touch.
Physical - probably an 8.5 here, great pace, strong for his size, balance is ok, fitness levels are very good
Social - who knows but there are no rumours of him being a party animal, I guess he could do with quitting the vaping though
Psychological - seems to show for the ball and keep trying even when he's having a poor day.
All in all, he's value for money, could easily be worth 2 or 3 times what we paid if he has a full season and gets 20+ goals.
