Leicester not winning another title may be FFP related but them getting relegated was completely due to their own mismanagement. For me, FFP has performed admirably. The league hasn't been this competitive, top to bottom, for 20 years. Teams like Brighton and Villa can keep its talent without having to bow to the financial might of the Chelsea/Man City types.
It can definitely be improved upon but to think we should repeal and go back to the way it was before is madness. We would be a mid-table club with no chance of a top 4 finish within a season.
