Or simply that as most investors do they are waiting for the bottom of the market to appear. Any investor worth his salt wouldn't invest in anything at the height of the market, they will sit idly by and watch and wait until the price almost hits bottom and then strike knowing that in the long run the price can only rise.
Personally I think that this "interested person" has been around for some time and may have had a few conversations with Krasner regarding a possible bid. If it had been me I would have asked for a few conditions to be met subject to signing any contract. I would have given him a firm offer subject to my conditions being met and that could be the reason he rejected other bids knowing that my bid would stand unless he got a better offer, a backup if you like.
The conditions I would have set would be firstly that the debt was paid and I had a clean slate upon takeover, secondly get rid of the second training ground which is unnecessary at league one level. Drastically cut the wage bill to make the club sustainable in the lower league and sell off any player who did not want to be playing lower league football.
I would have asked all that so as not to be coming into the club and having to sell off players thus causing a shit storm from the fans before I even got my feet under the table.
Sound familiar?
I can now enter the field as the clubs saviour and modestly invest to bring the playing staff back to a reasonable standard and be safe in the knowledge that I will receive no criticism from the fans and that my investment is safe, debt free
(every chairman in the league would be envious of my position) and sustainable for the forseeable future.
