In a squad as small as 20, it takes a handful of absentees before the majority of the bench is filled with kids that aren't ready. No team in the country is going to be happy with just a 20 man squad. This isn't about giving kids a chance, the kids Pep thinks are good enough will be handed a place in the squad and counted. Even if you assume all the kids taken on tour are included in the squad along with a third keeper, so Foden,Diaz,Tosin and Muric/Grimshaw and we leave out the players Pep considers deadwood that still only leaves us with around 23, the squad is undoubtedly lacking 1/2 bodies.
