Of course he’s got a good win percentage and an impressive CV, he’s only managed the biggest and best clubs in the league that they compete in.
His actual success comes 10+ years ago.
His style of football does not translate to the modern era.
He’s never managed a club that are in the position that we are in or with players as incapable as ours.
He’s beyond retirement age with zero motivation to succeed.
It would be an utter, utter disaster. Up there with Fulham appointing Felix Magath, only that actually made more sense than this.
