Alright, so lets say they do pull the sale off the table.
Could there be a case for market manipulation against them? They have over-valued the club (almost double isn't it? 3bn valued but asking 6bn. Then the Washington NFL team got sold for a massive price, so they apparently they upped the price even more. Then not communicating with either bidder or the group they tasked with selling for months, and anytime someone reported as coming close to the asking price, the asking price changed.
Could this actually make the share price drop and the club being worth less due to their actions? Meaning any future sale will never come near 10bn, let alone the 6bn reported as on the table now.
