Not being funny but If I'm a mega billionaire Yank/Sheikh, I'm not going to care about history. But I will care about taking a team who can Offer me a big stadium ready built that I don't have to pay for (yes, I am calling cardiff, villa etc more appealing), than Everton, who have an unrealistic sentimental related, price tag, which, when buying will still have to pay off debts, however "small", they are, and then fork out £100m+ on a new stadium.
This was obvious to everyone anyway. New stadium = New Owners.
