Leeds, even though Bates bought them for a pound and still fcuked up.
He still may come good yet mind but in the right hands Leeds could be a gold mine, the only club in the City and hard core following, they may not get the crowds we did when we were down there, but in the top flight they get a decent following.
Newcastle are probbaly on par with them but they are to far north and won't come cheap, If i was looking to invest then Leeds would be the obvious choice.
