The proof of funds in general seems ridiculously flawed ,otherwise all these clubs that end up in mess would not be .
I have heard it mentioned by quite a few people that a requirement for new club owners should be to put a % of the funds down on the purchase of clubs , like a deposit which is held in a neutral account much like used in housing rentals / mortgage etc .
Does not sound a bad idea in theory , and would in some scenarios offer clubs a degree of protection .
