He reminds me of a hybrid between Javi Moreno and Ricardo Oliveira ... good enough for the spanish league but completely out of the element in the Italian league.
From what I've seen I can't say that he's great at something ... Dribbling, aerial play, strength, technique, positioning, poaching ... all seem average. Even Doumbia has better highlights than this guy. Overall good rounded striker but far from a difference maker and let's not forget that he probably doesn't speak Italian and it will take him a while to get accustomed.
Haven't followed him and truly hope I'm mistaken but right now I'd probably have taken someone like Immobile or Gabbiadini over him...
