In terms of support for Manchester City... I think this likely boils down to whether or not your loyalty to City is based in large part due to ties of locality; if you're City born and bred, victory at all cost is likely (but not certainly) your opinion.
If you're a City fan not due to locality - you were born and live outside Manchester and more so outside of England but your favorite club nonetheless is Manchester City - then likely (but again, not certainly) style of play is going to be very important.

To wit:
As an American citizen, I really don't care how the US men's national team wins - yes, I'd prefer an exciting style, but if that means not winning, drop style and play ugly football.
But as an American whose favorite club is Manchester City, style is a very important part of my enjoyment in watching City play.
That said, a long string of success, such as that enjoyed by Brazil, may shift sentiment more towards style - that is, victory first, but victory must be accompanied by exciting football. At a club level, Real Madrid fits this mold.
