The Scot, who has been without a club since leaving West Ham, is hoping to get back into club management but will not rule out an international post
Former Manchester United boss David Moyes admits he would be interested in managerial posts with Celtic and Scotland if they became available.
The 55-year-old has been without a coaching role since leaving West Ham in the summer of 2018.
His reputation was enhanced during a spell at the London Stadium, having previously endured a difficult time at United, Real Sociedad and Sunderland.
