The players return from holiday, today, and we 'potentially' lose none of the players mentioned (Gundogan apart).
Bobb, McAtee, Lewis, Palmer and Doyle are all shouting for their chance. Even if all of the players mentioned leave, which is highly unlikely, the worst situation possible is that we enter the season with this squad.
Ederson/Ortega
Lewis, Stones, Dias, Ake, Akanji, Harwood-Bellis,
KDB, Foden, Grealish, Rodri, Kovacic, McAtee, Doyle, Perrone, Gomez, Bobb, Palmer.
Haaland, Alvarez
Personally, I would be happy to enter the season exactly like that. If we add some, it's a bonus. And, it is without adding any more academy talent into the mix, like Borges, Mebude, or Galvez, to name only three.
