Don't think nationality plays any part in this. The goal is to get players who will play their position with good outcome for years to come, like it happened with ofc Chiellini, Bonucci, but also with Lichtsteiner or Pjanić or Sandro. Locatelli seems like a natural choice and so does Donnarumma but I wouldn't loose my sleep if we won't sign them. The best idea is to buy players that worked for us in the past, meaning players already playing for medium big clubs who are not teenagers. And there are plenty of players like this on the market - Schlager, Tapsoba, Golovin, Gosens.
IMO most reports ATM are bullshit, they will meet today and we will see first outcome next week. I really would love to know what Allegri thinks about our midfield though.
