As Conte said, we can't afford to make mistakes in the transfer market. We have a narrow path to success, and it involves getting most of our transfers right.
A lot of damage to the squad was done in the Hitchen years, so it's natural it will take time to recover. But as you say, recruitment success since is still too mixed.
Very clearly, it's been good from Italy (Romero, Kulusevski, Bentancur, Perisic, Udogie). Mixed success from England (Bissouma, Richarlison, Spence). Horrible from other leagues (Emerson, Gil, Sarr). Still can't believe we traded Lamela (a far better player) AND £22million for Gil.
There are some signs Paratici is aware of this, as he's added to the recruitment/scouting team. Which hopefully will mean we can buy successfully from multiple leagues in future. In the meantime, sticking to Serie A has served us well, so I'm much happier seeing links from there than from other leagues.
