I've tried to wade through most of this thread and it's generally pretty good stuff.
Here's another analysis of the Etihad deal that is not from a City forum that seems to conclude the deal is within valid ranges. As I said earlier-getting money from Etihad certainly reduced search costs, but that doesn't mean they would not have been able to secure similar amounts from other sources.

I don't have a huge problem with the value of that deal, rather the source. It's fine to say that it is somewhat in line with market but I think everyone knows that no way would others have been willing to take that risk. Any sponsorship would have been far more incentive driven, and contingent on future success, rather than just being in line with the very best sponsorship in world football for a club that wasn't at the time at that level.
The most interesting question for me has always been and will always be: what does the Sheikh get out of this arrangement? These are the absolute facts of the matter:
1. He has no known previous affinity for that region of Manchester - this is not philanthropy that appears personal
2. He will NEVER get a return on his investment in City. He will have spent over 1bn to maybe swing 10m a year if things go really well. Literally sticking that 1bn in a savings account would be more profitable over his life than 'investing' in City
3. He doesn't go to matches. We hear that he watches from home, but if I had access to a small fleet of private jets and more money than God I'd at least go to my team's football matches
4. The main revenue for City has come from his relatives
The only conclusion I've ever been able to come up with is that you just can't apply business logic to sovereign wealth at that level. Abramovich I totally get - he needed to get money out of Russia, needed a UK domicile and actually appears to derive enjoyment from his asset.
City isn't an 'investment'. It is indeed, a 'project'. I just don't believe I'll ever have any idea why losing 1bn on a football team in some far off land is more advantageous than spending it improving your infrastructure, or even just investing it on the market and using the returns to better things. My working theory is that it's such a tiny amount of money to Mansour it really is just something fun to pass the time. Like us throwing a fiver on United winning the league next year.
