Sir Alex Ferguson has paid tribute to John Duncan after the former Chesterfield manager passed away at the age of 73.
Duncan guided Chesterfield to the FA Cup semi-finals in 1997.
A statement from Ferguson was released by the League Managers Association.
“I will always remember John with a great deal of respect and affection.
“When I was playing and managing in Scotland, I remember him playing up front for Dundee and then of course he went on to be an exceptional striker for Tottenham.
“I’ll never forget John, as manager of Chesterfield, leading his second division team to the 1997 FA Cup semi-finals which really was a fantastic achievement.
“John had such humility and a great sense of humour and I spoke with him only a matter of weeks ago. I will miss seeing him and I send my deepest condolences to his daughters, his sister, his partner and their families.”
