For PSR it is the Balancesheet accounts that matter. Yes most clubs unless run by a sugar daddy run on cash flow but with PSR you have to be careful when it comes to the amortisation of transfers. The fact is Chelsea can only afford the Billion Pounds Spent because of Amortisation over 8 seasons on Transfers and the fact that Abrhamovic ensured that part of the sale value was money set aside in Escrow. If the Premier League did what they should of done this season and ruled that transfers can only be amortised over 5 years because that was the standard practice of all clubs but Chelsea in the PL it would have fucked Chelsea and probably crashed the Transfer Market because they would have needed to get what they could for Gallagher and Colwill.
I coulda sworn this actually happened..... Obv they can't rightfully backdate a rule-change tho.
