Gordon Strachan has labelled Sir Alex Ferguson as 'the best of his generation' on the eve of the Manchester United manager's 20th anniversary at Old Trafford.
The Celtic chief, who played for Ferguson at both Aberdeen and United, has not always seen eye to eye with the veteran Scot but claims he always knew the United manager would be a massive success.
"I knew he would be a success there was absolutely no danger," admitted Strachan.
"I think I said when I was leaving United that, when at that time it was not so easy for Alex, they should give him a long-term contract because that's the way he works.
"And he has produced beyond the call of duty and not only at Manchester United, but he had a fantastic side at St Mirren and a fantastic side at Aberdeen.
"He is the best manager of his generation as far as I am concerned. I just know he is a special, special man."
