I think your wrong.The Allams can stop selling what they own at any time until the contract is signed. I can't see the FA insisting the sale goes ahead if the Allams say no deal.
The weight of evidence line gave me a chuckle too, some in the know posters, and some suggestions of what could happen in the Hull Daily Mail. That applies to both the American and Chinese buyers. When negotiations were announced with the Chinese the Allams also said there was another potential buyer ( a third party ) will they come to throw a spanner in the works?
The Americans got to the point of agreeing a price, but the Allams pulled out before they came over to sign the paperwork.
The Chinese have agreed the price, signed the Heads of Terms and paid a deposit. It's much further on.
