Yeah, you can do the same for most squads. I think our squad has a lot of good youngsters as well, our first choice defence could have an average age of just over 23 next season for instance.
I do not know. Chelsea look more balanced for me. Of their signings this Summer you can say that they have had hits with all bar Harvetz, but even with Harvetz he looks like someone acclimatsing to the league and not a busted flush. I reckon he will start playing like he was at Bayen within 6-12 months if he is played in a No.8 role and improves his physicality/shielding of the ball (not a particularly difficult thing to do if dedicated.)
After that, it is almost certain they get Rice. If they do that, they just need a CB as outlined and probably a CF. My concern here is that with such a squad with so many young players, they become very attractive to Haaland, especially as he seems motivated by trophies/achievements and not money. If you put Haaland and Rice into that team and they can find a decent CB between the age of 22-27 they will have both depth, amazing quality and a low ish average age.
I mean, look at this as a potential 2022/23 first XI if they sign those two:
Mendy (30)
James (22) Zouma (27) New CB (22-27) Chilwell (25)
Mount (23) Rice (24) Harvetz (23)
Ziyech (29) Haaland (22) Pulisic (23)
Average age: 24.8 years (based on the new CB being 26)
Average age of outfield players: 24.3
I honestly, do not see anyone else with that sort of age demographic and quality combined. Further, their bench would also still be relatively young with some very good players/young players with high celings.
