Let's see, a club where the spirits are in the dumps that needs a psychological boost more than anything is between two managers who both fit the club's "playing DNA." One sets up a scaffold to observe training from above, has some weird personal behavior, and is generally aloof. The other is a master motivator, father figure, who trains the players himself rather than leaving training to his assistants, and considers the club "his" club. Seems pretty straightforward to me who to pick.
As for your assessment that he will be in Munn's/Levy's pocket, what exactly in his 27-year career has led you to believe that will be the case? Can you give me some examples from his past where he has been a "yes" man?
