I can't see there being a CVA for the PLC as it probably isn't going to exit admin, it's going to be wound up.
I reckon a CVA could be arranged for SFC Ltd if needs be by simply orchestrating a pre-pack admin, prior to completion (assuming it is insolvent).
To be honest, if the creditors are happy with the deal and all football debts are paid I shouldn't think the FA would take any more action - they would only be increasing the likelihood of ending up in court and being made to look like a bumbling bunch of nitwits.
