Clubs like Chelsea, Man City and Newcastle United have negative operating incomes? That's not surprising. Much of it probably comes from wages and upgrading their facilities. It might not be a problem for the oil barons but one has to wonder what the hell Newcastle is doing... operating income doesn't even reflect interest payments on debt.
