Nottingham Forest have appointed David Pleat as football consultant.
Pleat worked with Calderwood at Tottenham
Pleat was Tottenham's director of football when current Forest boss Colin Calderwood was reserve team manager.
Calderwood said: "David won't be in and around the club every day but we will be in contact over the phone once, twice or three times a week.
"He has a good understanding of the game. I understand his strengths and we have a relationship which will be healthy and prosperous for the club."
