I don't know much about the new FFP rules, but I would imagine that they aren't going to take into account the purchase price of players, as that would count as capital expenditure, and then they have include depreciation of those assets, and how do you decide the value of a player, which may go up or down, or change with injury or a dip in form, and is also not even known unless they are placed on the transfer market?
No, my guess is the only part that matters for FFP will be the opex - wages and the club running costs, against income from gates, merchandising, sponsorship, and competitions.
If this is true then for Hazard they will only have to offset 13 million per year of income to pay his wages. Also of course, with sponsorship alone, the big clubs have a massive loophole, what's to prevent Abramovich taking the naming rights of the stadium for a subsidiary, at a vastly inflated price to boost the income. For sure they will have a whole army of accountants already working on the loopholes.
Another nail in the coffin for football... gonna be tough year for us to be sure
