This is the FFP rules before being amended from next season.
City borrow a further billion pounds on a soft loan and don’t pay back a penny but it sits there on the balance sheet as a debt. That money is then spent over a period of years on wages and transfers A new owner comes along, pays off the debt and we start again, that’s not what FFP was supposed to be there for.
Why should accumulated debt be allowed to be written off, especially how Chelsea did it? They circumnavigated FFP by funding the spending, it wasn’t income, it’s turned out to be a gift.
