Did Man Utd not inflate the market buying Berbatov for 31m, Ferdinand for 29m, Veron 28m, Rooney 27m, Van Nistelrooy 20m, Anderson 20m, De Gea 19m, Carrick 18.9 m, Nani 17.3m, Hargreaves 17m, i could go on. And the money isn't United's either really, its mostly borrowed from banks by foreign American owners. You sound like a bitter United fan to me.
That isnt true, the money is very much Uniteds. What the Glazers used to leverage the club is borrowed from american banks, but everything that gets spent (including the vast waste on servicing interest on debt the club shouldnt even have) is entirely generated by the club. I'd argue none of those inflated the market, nor have City inflated it through fees. What could be argued is that City have had an effect on the inflation of wages, but even that was something that begun with Chelsea, and is something that all clubs are actually guilty of.
