There are obviously things he does very well, he's got that electric pace but his close control to accompany is what makes him a real threat, the issue for me is how that fits into the current Wolves team. Not that it's ever a bad thing to have a player who can just skip past a couple of men like they're not even there but in isolation it can be all but useless, a lot of the time he seems to go on these runs and the only way it comes to an end is when it's out of his hands, either losing the ball or just gets the byline and chucks it in the box, has he got the right stuff upstairs to really make the most of those abilities and still fit in with the more considered football Wolves displayed last year? If he can't adapt to that then he's ultimately going to be a very frustrating player for Wolves, potentially capable of roasting an entire defence but rarely being able to take advantage of the situation and get the ball back into team mates that can finish it off, if he can't adapt then he might well take away more from the team as a whole than he adds with his individual strengths over the likes of Costa and Cavaleiro.
To me he feels much more like a McCarthy type signing, a standout in a lower league, performed well when played against and very much a 'give it him, watch what he does' kind of style for the most part, it just doesn't feel like the really fits the ethos of the side despite his plus points. Even the best players can fall foul of it too, Neymar being a strong contender again at the moment just thinking he's a one man team all the time, yes he's unbelievably talented but so often he could achieve so much more by realises that he's not the only person on his team.
