Also depends on who we keep joel

If we kept all the u23s, and ayling berardi debock jansson forshaw alioski Dallas sacko hernandez Saiz lasogga and ekuban from the over 23s, then I think we would need as a minimum a gk, a cb, a cm, and a St, all 4 would need to be at least as good as our current best players if not better. It could be argued that as well as those 4, we might need a lb and a winger too, it will also depend on who our head coach is too coz that will then determine what formation is used.

Gks stockdale marshall McCarthy
Dcs Bartley helander flint
CMs I'm not sure
St's Jaime mata, Federico caputo, or if British maybe grabban who's scored a fair few for 2 clubs this season

Lbs maybe Bryan or friend
Wingers I don't know

Head coach either McCarthy or Holloway
