What about the Everton link, converting to equity is writing off debt, I'm pretty sure if there was no sanctions he would have been free to convert as it was being said it was always the plan.The main issue is you cannot write off debt, that is a gift which breaks the rules and as the debt is in a sanctioned company it will need to be paid. Unless of course the government is kind to Chelsea and wavers the rules purely for them which I would not be surprised about.
If not the money has to be paid by the club not the new owners.
It breaks ffp when he pumps it in, either with debt or cash injection or it doesn't break ffp... I think.
