No chance we buy 4 players who improve the first team, while coming with economically realistic transfer fees and wages. Mason hasn’t got too many goals this season but his overall game has improved and he showed after lockdown what a great goalscorer he can be. Thus, he can occupy one of striker or RW, leaving one of hopefully Haaland or Sancho as the attacking acquisition. Buying the former will probably require £100m and latter £80m, less if Dortmund don’t make the CL.
At the back, Maguire-Lindelof/Bailly is not as big an issue as McFred, or even one of them/Matic next to Pogba. We need someone who can partner Pogba as the defensive-minded midfielder. Ndidi, Rice, Tapia and Berge are all decent options, with the former two obviously the dream signings. Ndidi will be unaffordable considering Leicester don’t have to sell, so I’d go for Rice for £65m if West Ham don’t make the CL. Latter two are the alternatives, probably at £25m each.
A bonus will be to buy a cheap backup RB who can challenge AWB. Mbabu or Aarons would be nice, at £30m.
Most likely though, we’ll buy two players, one in attack and one in defence while making Dalot backup RB at a cost of around £150m, slightly offset by the sales of the likes of Williams, Jones, Matic, Pereira, Lingard, and release of Romero, Mata and Cavani, who seemingly already has a foot in Argentina.
