Regardless of how City was 'made', I am glad they won the title. They fully deserve it; they play the best football, have the best attack, the best defense. I hope they do some damage in the Champions League next year because they can challenge big teams.
As for the debate concerning the financial power of City, I am not so much against it. They did what Madrid (Ronaldo, Ozil, Benzema...), Barcelona (Eto, Ibra, Sanchez, Alves...), or any big team have done in a shorter span. Instead of spending millions in an interval of 10+ years, they did in 3-4 years. It would be reasonable to argue that they would keep spending millions each year, but, seeing the strength of their team at the moment, I doubt they will. They would probably sign a player or two each year, like all teams do and limit their spending. The fact that people are seriously attacking City because of their money spreeing but disregarding Madrid's -- for example -- use of their large funds is a little unfair. Madrid, like City, and especially the last decade or less, aren't prospering their youth system but rather are spending it on foreign stars. It shouldn't be okay for Madrid because they are a bigger team than City. I just hope City is satisfied with what they have otherwise it would be a little unfair especially to teams like United who are always satisfied with their players and still manage to challenge for titles and Arsenal who are just too 'cheap' to spend. City basically built a team from scratch, true, but I guess this is the only way to challenge United for the title and presumably end their dominance. Liverpool is way far from challenging anymore, so it Arsenal.
Also, I'm betting Chelsea will probably spend a lot this Summer; 6th place -- despite being in the CL final -- isn't appealing to their owner. Same goes for Liverpool.
