I think we have a somewhat decent first XI, but the change we need to make for next season is to have rotation options that won't significantly weaken the quality of the team.
I see the solution with having 5 players capable of stepping in, so that in a month with 8 matches, no one needs to play more than 5 or 6. This way, we keep the best players fresh troughout the season.
I think we can do this with four aquisitions, even if we sell the six stated below.
For summer 20 I'd like is to sign Sancho to raise the quality of the first XI, Grealish to get both versatility and quality, a CM that can play with both McT and Fred, of PL quality, and another striker to add numbers (either a youngster or someone older).
Out: Pogba, Jones, Rojo, Smalling, Sanchez, Lingard
Total approximately £160 million
In: Sancho, Grealish, Rice, Boadu
Total approximately £260 million
Net £100 million
First eleven:
DDG, AWB, Lindelöf, Maguire, Shaw, McTominay, Fred, Sancho, Fernandes, Rashford, Martial
A strong first eleven. Three players that need to improve in 20/21 are Lindelöf, Shaw and Martial, or summer of 21 we'll need to purchase a CB, LB and striker.
Regular rotation players:
Romero (GK), Williams (RB, LB), Tuanzebe (CB), Rice (CM), Grealish (CM, AM, LW), Greenwood (RW, S)
With proper rotation these players Will be seen as basically regular starters.
Squad players:
Dalot (RB, LB), Bailly (CB), Matic (CM), Pereira (CM, AM, LW), Mata (RW, AM), James (RW, LW), Boadu (S)
These players should only play 1-3 matches a month, so that they are fresh and hungry when er need them.
If we need minutes from anyone else we can call up Laird, Mengi, Garner, Levitt, Mejbri, Ramazani etc., unless they go on loans.
