If the ultimate aim of Citys majority share owners was "Sportswashing" then you'd have to say they failed miserably., as its been counter productive at best. Didn't read much about Abu Dhabi in the UK media positive or negative, prior to the Mansour takeover at City in 2008. Now its an endless stream of negative headlines and under a constant spotlight.
I'd argue that their ultimate aim of the foray into Manchester was mainly financial as oil, a fossil fuel, won't last forever and they needed to future proof their income stream. Possibly with a a small side order of vanity project too. In this respect Abu Dhabi have been VERY successful.
These are very clever and shrewd business people. Which is more likely? Attempt to gain favour with the west, fail miserably but, luckily, hit the jackpot financially? Or have a sound strategy for success and achieve it?
There may be numerous reasons to castigate Citys owners but this isn't one of them. If theres been any underhand deals going on, and thats a big IF, then its the vendors of the land in question that need examining? Look no further than Manchester City Council.
I guess that doesn't generate clicks though.
