What utter tosh and clear evidence you have zero understanding of how a business is run. The money we save, in your instance £10m, pays wages be it staff, players or anyone for what it’s worth.
Also if City just cough up £5m here or £10m there then every deal we do going forward means we get that amount added on. Of course we can afford the extra money but that’s not how business’ operate, I’m sure you could afford an extra £10 being added when filling your car but does that mean you should or have to? No!
Successful companies and individuals don’t become that way by just flirting away their money for the shits n giggles.
