The football club is worth no more than a quid. You wouldn't buy limited goodwill and a company that loses a fortune every year, knowing you would need to throw a fortune at it to hopefully progress for any more.
The real coins sit in the assets that will soon owe the current owners more than they are worth, if Wally and Co walk away with their money back they will have done well.

Taking the 12mil debt, the investment the squad seems to need and the improvements needs to keep them at the Mem for a few more years whilst they try and find a new home, can't imagine there would be much change from 15 or 18 million as a year one payment.
And of course, who knows what will happen to the economy post Brexit...
