Tbh I still think he can keep improving, this isn't his limit yet. His tactical awareness is higher than Hakimi, but he is also older. The thing I most appreciated with him is how well he adjusted to serie a (Inter), and being a good player doesn't mean you can adjust. It requires attention to detail and preciseness and a certain mentality. Like I can name some kids that are more exciting, like João Mário (Porto) but for them to succeed at Inter, they probably going to have to go through at least half a season rough patch and all the fans will shit on them and if they can get through that, then yea, but lots of the time they stuck into a downward spiral forever.
P.S. to me he is pretty all rounded, the speed, the strength, header, crossing, off ball movement the things he doesn't have is dribbling skills to beat his man and long distance shooting. The less hesitation he has the more lethal he will become.
