The carpet baggers have set an unreal price for the club - a club needing major infrastructural improvements and squad financing on top of the price being asked for shares. If you're a buyer you look at it and think two things: 1/ WTF have these people done to ask for cash like that?, 2/ It's a sales pitch based on revenue from a volatile source that can leave the game just as soon as it entered it.
In short, you'd need your head feeling handing over £225M for a PL club with no new stadium facility, no massive commercial arm to it, and a good but not top 4 class squad.
We'll be like this until Kenwright leaves. There's not a buyer out there who'll touch this club with a barge pole.
