His issue isn't ability, it's a combination of end product and it feels like (watching him live is different from tv) he doesn't give 100% (kind would be calling him tentative, not so kind, he's not brave)
Burnley game was better re end product, he took it on himself to shoot more, that will improve, taking it a little earlier, learning to place better and/or hit harder, he was more of an outlet for the Porro ball.
He still doesn't really go in for 50/50's, he still can be slow to run back or take his man on (watching him switch sides and have his first half position taken by Gil is telling, regardless of opinion on Gil), lot of improvement possible with him.
