No doubt, his technical abilities and physical are really good, especially physical, but his final product is awful. He's like a complete opposite to someone like T.Muller, Muller is just average technically and physically but his tactical awareness in all aspects of the game are unreal.
He had bad luck with teams, even when he did something decent Negredo and others would let him down, I do believe he can still learn and improve in that aspect of the game, his individual qualities are far too high for him to fail as a player.
Premier league suits him with lots of open space and running, but he'd have that as well in other leagues, he needs a good coach to learn him the basics and only after that I believe he could accomplish something.
I'm just blown away with his speed every time I see him, I dont think I remember another player that was this dominant in terms of speed, he's like a real version of those FIFA 15 speed demons.
