If anyone thinks that someone with no affiliation with a football club is going to put money in for nothing out, then they have been led down the garden path. there are one or two like chelsea and man city that appear on the face of things that they have owners that are happy to throw an never ending amount of money at the club, but there are more foreign owners that have either come unstuck or started to move the club away from it's fan base. Cardiff, and Hull? Then the owners of Birmingham and Portsmouth? Even if they are just taking a salary in leu of interest then they will be doing it for some sort of return. Even Arsenal, which are probably the most finically secure club in the UK, have investors that get a return on their money. Liverpool, the Vile and Man U have all had their fall outs with overseas ownership.
The Thai investors at Leicester look like a good deal on the face of it, and I'd swap with ours in the blink of an eye, would want to keep elvis over pearson, but would not be shocked if something happens and it starts to go pete tong. Rich people get rich by either being in the right place at the right time (luck), Hard work and being roughness, illegal or immoral means, or a mixture of two or more, not through owning a football club and throwing cash at it. When it starts to go wrong and the fans start to call of the head of the manager then more players then another manager then the board, lets see how it pans out then.
