We'd need a millionaire/billionaire who just wants to have a lot of fun and take a team to new heights for pleasure. Someone like Jack Walker, but I doubt there are many other Blackburn fans worth £500m+. So that would leave someone like Abrahmovich who is doing it with Chelsea because he can. How much money does Wayne Hemmingway have?!
What would be terrible is if we end up with someone who'll put loads of money in, and then get bored really quickly and leave us in the lurch, some dodgy Russian who may end up poisoned/asset stripped by the Kremlin, or a complete nutter like Mr. Romanov at Hearts.
If I make £100m+ I'll buy the club.
