I think with this team they are able to challenge city even more by creating more depth.

Sell:
Partey
Jorghino
Gabriel
Gabriel Jesus
Smith rowe
Nketiah

Buy:
Zirkzee
Rutter
Xavi Simons
Eze
Vitinha
Colwil
Hernandez
Camavinga (impossible I think then just Vitinha)
Antonio silva

By doing so they create more depth and can structurally challenge for the title.
