The rules were a load of shit anyway. No investing in your business, got to not make a loss. Right, so we just needed to reduce our wage bill - oh wait, we can't, because once you have the players, they've got guaranteed contracts for X amount of years, and you can't just make them redundant, you need to sell them to other clubs, which you might not be able to do because they can't afford it. We were never ever going to avoid falling foul of FFP, the expenditure had already happened in earlier years and we were stuck with it once the rules were introduced after the fact. The rules were written deliberately so that we would fail them. The reason it took this long was because the Football League clearly ballsed up their attempt to write the rules and left them too vague, so we've managed to get them to back down a bit on the amount.
I notice no-one in the media bangs on about Bournemouth failing FFP, or Forest, or the many other Championship clubs that have failed them since. Its a set of crap rules which prevents a level playing field as it gives a massive advantage to ex Prem clubs with parachute payments whilst preventing smaller clubs growing by preventing investment.
