I guess right now I'd look at the club like this, with the players not part of long-term plans (Cristiano) excluded:
Striker: #9, Martial
LW: Garnacho, Rashford
RW: Sancho, Amad
#10: Bruno, Eriksen
#8: Fred, Eriksen
#6: DM, Garner
RB: RB, Dalot
LB: Shaw, Malacia
CB: Martinez, Maguire, Varane, Lindelof
GK: De Gea, (Henderson), ________
Ideally, you'd sell McTominay, probably Elanga while his value is as high as it's likely to get, and raise real money - along with anyone not on the list going for peanuts to save money on wages - and if a young CB or Zidane or Savage or Amad plays too much then who cares we're likely not making the CL anyways, and buy the 3 players in black this month and then next summer, sell Henderson, De Gea, Shaw, Maguire, Fred and replace them with Fernandez and new signings at GK (and a cheap backup on a free), CB, and a #8 is another 3 big signings for a squad like this next year:
Striker: #9, Martial
LW: Garnacho, Rashford
RW: Sancho, (whichever youngster wings the backup job)
#10: Bruno, Eriksen
#8: CM, Eriksen
#6: DM, Garner
RB: RB, Dalot
LB: Shaw, Malacia
CB: Martinez, Maguire, Varane, Lindelof
GK: GK1, GK2
