Not only approved, but did not break the rules as the EFL cocked up that bit when formulating the new ffp rules.
HOWEVER, where they MAY have failed is over the stadium valuation at £81m. Even though they could sell the stadium , as they have done, EUFA rules say that sale of any such asset has to be at fair value and I think most of us on this thread were more than sceptical as to Derby's valuation.
Unless there is another issue we don't yet know about, my guess is that the EFL have had their own valuation carried out on Pride Park. If it is substantially lower than that which Derby applied, then I would then assume they have re-worked the ffp calculation based on the profit ( or otherwise!) based on the lower valuation. If this resulted in losses over the 3 years in excess of the £35m(?) allowed under ffp this would trigger the action now being reported.
P.S. Has the EFL copied and pasted this thread to use as evidence in the case against WR'sDCFC?
