They won’t be because they are the darlings of the media, City get slammed in the press and their financial spending is deemed unfair but their owner could match any of their debts many times over due to his vast personal wealth. Financial fair play wouldn’t have been thought of if Man U, Arsenal and Liverpool were still the big boys winning most trophies most seasons but there not the leading trophy winners now in terms of volume over the last few seasons hence the fair play rule invention. No time for any of em really because the ethos of the game went out the window when the Premier League was formed and the game became all about money. It will never change until a time the Government of the day brings in proper financial regulations governing football and that won’t happen whilst capitalism is God and the pigs keep feeding in the money trough.
