He's a Championship assistant manager who gets a Premier League manager's gig by accident and now probably a Premier League manager's payoff.
If there's anyone to feel sorry for here, it's really not him. No matter who the coach is that club deserves to be bottom. Better he got a way out now than to drag it on and then get sacked later on. I don't think he was doing a terrible job and I don't think it's really harmed his chances of getting another manager job if he wants one.
