Tbf Fergie's intentions in latter seasons were unclear, to me anyway, selling Rooney and while the likes of Chicharito, Cleverley, Anderson etc. remain seems rather bonkers to me.
Fergie did break his philosophy as well to sign RVP in final season, for glory, pretty much.
Ferguson bought RVP and Kagawa to replace Rooney. The original plan was Kagawa and Lewandowski, but he didnt want to go anywhere but Bayern.
