I don't view guardiola as revolutionizing anything, at all. This isn't his first season in the PL, lest we forget.
I view this city side though as being a collection of superior players amassed over 3 managers, while Utd bought very, very badly.
Players like Aguero, Silva, de Bruyne, Sterling, Fernandinho are all players that guardiola inherited, and that in many cases throughout the city side, have already won, and dominated the PL.
If anything, I think that their current form and inevitable PL title this season should see Utd realize that they need to get serious - as city did when they began the guardiola project 5 years ago.
We shouldn't be ashamed of spending money because we, unlike city or Chelsea, generate our own - it's Man Utd's money, not the money of some corrupt, archaic oil tyrant. And so we mustn't be duped by the Utd hating media into thinking that our spending is the same as these other clubs, because it isn't.
We deserve to spend, because our money is built from our successes. And spend we must.
If the people in charge of the club want to rival city's 5 years guardiola oil spree, they need to be looking at putting in huge amounts, and buying at least 3 or 4 genuinely World Class players throughout Jan and the Summer.
I trust Mourinho's spending, I like how shrewd he is, and I trust his desperation to put the sheik's club back into their place. It'll be down to the money men to either be happy with Top 4, CL footy, or to show that they really, truly mean business.
