I've derided Wenger's repeated flattering to decieve at Arsenal, but I think he's a fantastic coach who has got stuck in a rut trying to prove everyone wrong. He isn't a strong leader as such but he does empower players, if he stuck with the likes of De Jong (and possibly Tevez) the mix could be perfect, reminiscent of the mix of steel minds and silky skills that he had with the invincibles. I'd be worried that he might not let go of his flawed principles of playing young and weak players in key positions.
If he was forced out at Arsenal he would be head and shoulders above every other candidate, Mourinho included. It's a pipe dream however, there are a million reasons he'll get at least a year under Kroenke.
