I think City knew all along that FFP was coming in some form or other, and thus really had (and still have) to give out the impression that we are to become self sufficient. It may well be true, but even if it wasn't, that's the impression that has to be given out in order for us to claim our investment intentions are on a sound business footing and not a sugar daddy's folly.
But probably more important is that I don't think Abu Dhabi wants to be perceived as an oil rich nation who 'plays' at business abroad. It wants to be seen as having a formidable reputation for business. Given that, it's important that City are seen to be making genuine money on it's own merits, albeit after the initial heavy investment and turnaround. Under their stewardship, we're acting far more professionally than we've (arguably) ever done in our history (certainly recent history).
In truth, I think City are over egging the pudding a little bit with regard to how quickly we've been turned around - but that's partly because UEFA have forced a rapid growth upon us. The mantra of 'European Elite drawbridge being raised' was accurate, and we had no time to spare if we were to stand a chance of entering that elite.
The football landscape is changing, and UEFA are finding themselves coming unstuck. They've traditionally been at the mercy of the elite clubs, but now, sponsors and new money clubs are creating a very blurry landscape for UEFA. No longer are the big clubs the only real voice to be listened to, and the biggest influencer of all - money, is something UEFA don't want to lose out on by backing the wrong clubs. IF City and PSG are truly going to be part of a new wave of money in the game, then UEFA won't blink an eye about tossing (say) AC Milan overboard if they aren't bringing in the same amount of glamour to CL. At present though, UEFA aren't really sure City and PSG (and others) are the future, hence their tendency to back the old guard. Give it time though.... like any band of thieves, there's little honour amongst them. They'll turn on their own 'elite' clubs the moment those clubs can't offer much, and we can.
