I honestly don't see FFP working. Too many leagues all working under different structures and vastly different laws to start with. From the ease of obtaining work permits in certain countries to the tax free haven at Monaco. Every FA would have to agree to work with one another regarding every single aspect and make it equal in every way, which ain't gonna happen. A lawyer involved with the Bosman ruling is already preparing to go to court.
