It's hard to get your head around the riches of Abu Dhabi. City don't have actual sponsors. They use their 'Sponsorships' (of the Abu Dhabi airline, Abu Dhabi tourism, Abu Dhabi hair cream etc), to retrospectively cook the books to avoid breaking rules to do with spending. They have manufactured the illusion that certain attendance packages are being sold. They are not being sold at all, these are just another vehicle, cooked up by accountants, to inject money invisibly. So it's all about utterly soaking City in a bottomless pit of oil and corruption money. None of it, or let's say only a miniscule percentage of it, derives from football. Those accountants, and the people who 'influence' on behalf of City are as important to the success of the team as is Aguero or Pep. That's the difference between them and the other clubs in the Prem.
Now I don't watch pro wrestling. I, and I hope I am not alone here, like sports with actual competition. A reasonably - with imperfections of course - reasonably fair one. For example if I heard that MUFC were being paid to throw matches, or De Gea to let in goals, I would no longer support them. If I heard that someone had bought the Premier League, and that it was a competition in name only, that one team could flout the basic tenets of company competition and fair play, completely work around the spirit of the game, a big part of my interest would simply wither away.
The key to wrong-doing is the fact that City needed to go to such lengths to hide the level of non-football investment.
So. The real wages of players. The real investment in stadium, facilities, players and management team. That was info that had to be concealed, the emails show. That info had to be kept away from the FA, the British press, UEFA, the fans. If the owners and the club themselves thought it was fair, why go to all that bother? Their actions show that they are cheats. They are not worthy Premier League champions. They are Manchester Cheaty, nothing more, nothing less.
