FSG have seen the writing on the wall. Liverpool did not prove to be the cash cow they expected.
The club has limited potential for growth without serious investment - having backed the cheap option to extend an outdated stadium with no scope for development. Their club and fans are disliked to the extent they are finding it hard to attract new interest. Everything about them is ageing, including their history.
It is hard to make a business case to justify a premium price when the competition grows stronger offering more scope and options. Buyers will not want the baggage of Heysel and Hillsborough let alone the fanbase. It could prove a harder sell than FSG anticipate.
