Hughes did sign Kompany and De Jong, really good signing, despite De Jong being very expensive compared to what he could have been. I'm glad we didn't gamble though.
Given, Barry, and zabaleta has been average, with zabaleta maybe as the guy above average.
Bridge has been pretty average, but I'll give him a minus.
Lescott and Rsc has been the two worst signing in the history of English football. Well I'm sure its not far off anyway, absolute garbage, I'm quite honest embarrassed like nothing ever before buy those two signings. Adebayor is pretty poor as well, Toure started off bad, but has probably risen to slightly above average.
But really there is little point in comparing, there is so many factors to take into account. The position city were in when they got appointed for instance.
