The proposed Newcastle United take over by Saudi fell through because of their (Saudi) appalling HR record.
No it didn't. It was likely because the Big 6, calling themselves Project Big Picture, are trying to financially support the rest of the league in exchange for preferential treatment and ability to interfere in some of the key areas currently governed by the FA. One of those areas is deciding who is able to buy any of the member clubs. It is probable that Mark Burrows and the FA knew about this plan and the delays in deciding on the proposed Saudi ownership, plus the lack of transparency since the decision, points to the Big 6 and the FA conspiring to keep the biggest pockets of them all away from their cash cow. So much so, that several parties have appointed big time QCs to take the FA to task on this.
I'm sorry to say that the FA, just like F1, don't give a s**t about anything that the Saudis are alleged to have done in their own country. They only care about money and power and the Saudis pose a threat so powerful that the other owners, perhaps Man City's Shiekh Mansour aside, don't want them in their profit machine.
Ask me how I know. I won't tell you.
