There will be some faux outrage and then life will continue. Man City have hardly been tainted with the way the word owners got their money.
Far from it. To be honest - perhaps I'm being unfair here - when I do see or hear a fan talking in a football context about their disgust at the billionaire sports washing clubs, it normally comes across as a supporter of a rival club grabbing and using any available stick to attack an enemy, rather than as a principled stand from a person who is truly troubled by human rights issues and who would simply prefer petrostates to stay away from the game.
Perhaps that's just my cynicism though as there is no real way to identify the motivation behind such complaints.
But obviously it's too late to make any sort of stand. Unlike socialist US sports with their rewards for failure (weaker teams getting better draft picks) and control economies (wage caps), football long ago cast aside any of that "all shall have prizes" mentality in favour of super accelerated greed-is-good capitalism in which rich clubs win more stuff and get more money to buy better players and win more.
Once they allowed rich owners to distort the market they could hardly stop dodgy used car salesman types from stepping in - perhaps it was a little odd that people who would be banned from opening a business were given the keys to the hearts of communities, but once they had been then why not Abramovich? And if him why not Abu Dhabi? And if them then surely there was noone alive who thought that a line would be drawn before the Saudis.
Interesting that the details have to be kept secret from the public though, I guess the deal is just so honest and above board that it risks embarrassing other industries.
