Hitzfeld is very close friends with Fergie and I think he told Fergie that he wouldn't want to take on United after Fergie.
Moyes will take over from Taggart.
As for us, I think Klinsmann would see us as a way of proving that he isn't out of his depth in club management. I mean, it's a daunting task for your first club managerial role, 1. taking over at the biggest club in German football and 2. taking over from a football managerial legend in Hitzfeld.
However, I don't see him being Villa boss. Purely because if he is friends with Randy, as we are led to believe, then I think working for Randy becomes a big risk and potentially puts a strain on their friendship. Especially should things not go to plan.
