Ex-Forest star Clough, currently manager of Burton Albion is a 12/1 shot to follow in the footsteps of his late father but is more likely to join forces with Stuart Pearce at Manchester City according to reports.
Former City Ground boss Hart is a 20/1 shot. He has been out of the game since leaving Barnsley last season and was mentioned as a candidate for the Cardiff and Notts County jobs earlier this summer.
