Simon Jordan believes Celtic and Rangers have become a 'stepping stone' for managers but does not expect Ange Postecoglou to leave for the Premier League at this stage.
Postecoglou's name has been mentioned by supporters as a potential option to replace Jesse Marsch following his sacking from Leeds United on Monday.
Carlos Corberan is currently the bookmakers' leading favourite for the job, although The Athletic have reported that Leeds are 'weighing up an approach' for Rayo Vallecano boss Andoni Iraola.
