As people have said you'd initially always want somebody local, a supporter who knows the club and what it's about, but the chances of that happening are super slim.
My ideal new owner thinking realistically would be a wealthy Chinese business man, or somebody from the Far East, not involved with oil, but in the areas over there i.e. Manufacturing where the recession hasn't hit.
This has a few benefits really, mainly of course that over there, investors at this moment in time will have more cash to splash but also i think it gives them another aspect to their investment, in the Far East football is still low down on the to do list, it's not publicized as well as could be and there are massive gaps for improvement. Anyone could see the potential in investing in a successful football club whilst perhaps building academies in the Far East, helping talent from areas such as China or the already rather well developed areas footballing wise such as South Korea would be of benefit.
I don't expect complete unity with the manager, i expect a workable and fair relationship, they don't have to be at every home game just make regular appearances and keep us posted with what is going on.
Clear the debt, after this is done, if feasible attempt work on the Football Quarter idea or new stadium if that is the end result and a decent transfer budget each season plus the security that the manager can use any profits from player sales.
Stay connected with the fans.
It seems like a long list but it's not bloody hard is it!
Ugh! YANKS OUT NOW.
