Where exactly is the literal quote where Fergie even mentioned Guardiola's name? I searched the Mirror website, the rag that supposedly orginated the story, and I couldn't find head nor hair of the article. One article I did find though, was one propositioning Laurent Blanc as his replacement ahead of Pep et al, which is telling.
The Pep to Arsenal conversation is amusing by the way, you might as well speculate on Johann Cruyff putting back on his boots and joining the Gunners - yeah, he might be approaching organ failure in his timeline but never mind facts when they get in the way of a good fantasy and a supposed meshing of styles.
