As things stand I see no difference between this guy and De Ceglie. Both looked promising as Fullbacks to start their careers, lots of potential, seemingly lots of talent, but neither seems a very motivated or driven to improve type of player, and it's shown as they both stagnated and even regressed as they moved into their mid-twenties. It was more obvious with De Ceglie as he was trying to fight for a spot at a top club in Juve, whereas de Sciglio has had it easy without much competition for spots in an awful Milan... but he's likely to be an unreliable backup at best imo. I hope he surprises me and starts working a lot damn harder to fulfil his potential but seems unlikely.
