Jim McLean was born into a working-class family in Larkhall, Lanarkshire on 2 August 1937, the second of three sons of Tom and Annie McLean, and grew up in the nearby village of Ashgill. His maternal grandfather William Yuille had been a professional footballer, playing for Rangers before the First World War. Tom McLean, a baker, had been a promising junior footballer before joining the Plymouth Brethren when he married. The three brothers, Willie, Jim and Tommy, who all went on to become professional football players and managers, had a strict religious upbringing.

After he had been coaching at Dundee for 18 months, the club's local rivals Dundee United offered McLean the position of manager to replace the retiring Jerry Kerr in December 1971. He accepted the offer and began his managerial career at the age of 34. McLean immediately started a co-ordinated youth policy which was to produce many fine young players over the two decades which followed. In the short term, he used his knowledge of the Scottish scene to buy experienced players who would allow him to re-shape both the squad and the style of play in line with his approach to coaching.  Initially, the club's league form was average, remaining mostly mid-table for the next few years. McLean's first hint of the success he would later achieve was leading the club to its first Scottish Cup final in 1974 and, despite defeat, it proved an important psychological step in McLean's and the club's development. The success of the Cup run was built upon the following season with a finish of fourth place, the club's best finish in the First Division before league restructuring.  As McLean's youth policy began to bear fruit, the first of a number of talented young players began to emerge. McLean decided that his team should mount a challenge for the League championship in 1978-79, something of which the club, who had long lived in the shadow of McLean's former employers and rivals Dundee, had never previously proved capable of but after a poor finish in the first season of the new Premier Division, United started to prove that they were serious contenders for domestic honours.  In December 1979, McLean guided his team to triumph in the League Cup and retained it a year later. At the same time as the club was enjoying a high standing Scottish football, McLean was gradually building the club's reputation in Europe, with wins over sides like Barcelona, AS Monaco, Borussia Monchengladbach, PSV Eindhoven, Anderlecht and Werder Bremen.
