I suspect that SISU want to acquire the Ricoh (and possibly surrounding land) for a song not because they want to run a football club but because they want to sell it and raise the money to repay their investors. Nobody has ever got a sniff of who their investors are, makes you wonder, doesn't it ?
But they are likely to be the type of people who would not take kindly to Joy telling them that their money is down the kermit. I think the recent insistence that they must own the Ricoh, freehold and all results from pressure from SISU's investors.
The danger is that SISU would sell to the first person who offers an acceptable amount. (I don't believe SISU will accept a deal for the Ricoh with any restrictions or covenants attached). If that first person is a football club owner then good news, providing they sell the club with it, but if it's a developer, things might get mega difficult.
