That's a great point. Even with United (and Chelsea somewhat) you can argue that there is a plan in place not just to win, but for the sustainability of the overall Club. I have never ever heard one City supporter indicate that there was an actual plan in place other than to simply throw money at problems.
For instance, look what they did with some of these new kids that they are bringing into their reserves. They are signing 16yr olds to 4 yr deals and signing them to £25-40k per week on day one (and then escalating from there). It's just plain idiotic to try to grow your teenage talent that way.
No one can throw this unrealistic level of money at a "project" forever.
Am convinced that the day that Berlusconi decides to sell Milan (or something like Juve), that Mansour will discard City like a new pair of shoes that were never a good fit and that never shined the way he wanted them to.
