I guess this is how the list breaks down:
List A - 25 players.
17 free spots
4 spots reserved for club trained and
4 spots reserved for association trained
1) Free Spots (max 17) --> 17 filled
Alisson, Ekitike, Endo, Frimpong, Gakpo, Gravenberch, Isak, Kerkez, Konate, Leoni, Mac Allister, Mamardashvili, Robertson, Salah, Szoboszlai, Van Dijk, Wirtz
2) "Club trained" (4 spots reserved) --> 2 filled
Bradley, Jones + 2 spots not filled
3) "Association trained" (4 spots reserved) --> 3 filled
Gomez, Woodman, Ngumoha
Guehi would take an "association trained" spot if he joins. Rio & Leoni would join the "club trained" group in 1 & 2 years respectively. So basically Leoni took Chiesa's spot.
