Money has flowed into the competition on a massive scale; in fact the majority of clubs are running on a false economy, if the external money dries up they will be unable to fund the running of the club. Only the few have a source of commercial exposure which will soften the blow.
The issue surrounding new owners is pretty simple, what does the club offer that would attract a new owner?? EFC have nothing where a potential business could look and find a marketable solution, and it all falls back to the stadium. A company/new owner would want a return on investment (apart from City and Chelsea) every other clubs owners wants something back. Utd and RS have there global exposure, the commercial deals will keep on rolling in for them because of the brand.
If there is that much money to make out of a football club, why hasn't nobody paid £150m; if there is that much money to be made out the Premier League then £150m is a small fry considering the potential return on investment. The problem is there isn't that much money to be made, it takes a serious sum of money to compete at a high level, and pumping that much money in you will want a return. Even drop the asking price to £80m; are you going to get that return back at a reasonable rate???
