I’m hopeful on youth too. Certainly think nothing needs to happen at FB recruitment wise for awhile. Beck could become the back up to either Tsimikas or Robertson. Bradley back up to Alexander-Arnold. Williams may move higher up the pitch or move on. Quansah, Billy the Kid or Rhys Williams between them may mean we don’t have to recruit much for CB. Loads of goal keeping prospects and older free/cheap keepers out there to sort out back ups to Alisson and Kelleher.
Midfield I’d look to bring a cheaper but still young guy who can be a squad option initially but hopefully force into the reckoning as a potential starter once settled. Boubacar Kamara should be a free option, Ryan Gravenberch will have 12 months left. At least one of Milner, Ox or Keita should be moving on which would create room. Maybe Tyler Morton or Clarkson getting more responsibility and game time too. Think Balagizi could start getting a look in as an AM type back up to Elliott and Jones. That would basically be AM part of CM sorted for years to come, club developed and young.
Then the following year summer 2023 maybe recruit big for CM?
In attack as you say ideally one big star goes in 2022 giving enough in fee to help recruit their replacement. Maybe Minamino and Origi replaced by a combination of youth guys like Gordon, Blair and Musialowski whilst maybe a free signing like Sardar Azmoun could offer depth/experience.
Then in 2023 or 2024 we bring in another star attacker. Maybe 2024 if one of the three starters extends their deal and stays a little longer they could then be replaced by the new manager who can select his own new forward to help change the team to his tactics. Leaving just one of Salah, Mane, Firmino as the older head to help during the transition.
Or we sit Klopp down in front of the few bad games he’s had here on loop till his resistance is broken and he determines to stay and fix it
