Duff has developed into a Mourinho type manager no doubt leanred from him at Chelsea. He is feisty and creates a siege mentality in his team ''everybody hates us''.
Not sure if he is ready for the championship yet however. You won;t know until you put him in the job.
However I do not see it ending well for this reason. He doesn't suffer fools gladly. He walked out of Ireland assistant job because of the FAI. You can only imagine him under ace CEO Steve Waggott and the Chicken molesters. He'd walk.
