Context: Sir Alexander Chapman Ferguson, CBE (born 31 December 1941) is a Scottish former football manager and player who managed Manchester United from 1986 to 2013.  He is regarded by many players, managers and analysts to be one of the greatest and most successful managers of all time. James Leighton MBE (born 24 July 1958) is a Scottish former football goalkeeper.  Among the clubs he played for are Aberdeen (two spells), Manchester United and Hibernian.  Leighton was part of the highly successful Aberdeen team of the 1980s, which won three Scottish league championships, four Scottish Cups and the European Cup Winners' Cup in 1983.  Alex Ferguson, who had managed Leighton at Aberdeen, signed him for Manchester United in 1988.  After he conceded three goals in the 1990 FA Cup Final, Leighton was dropped from the United team for the replay.  After short stints with Arsenal, Reading, Dundee and Sheffield United, Leighton rebuilt his international career after he moved to Hibernian in 1993.  He returned to Aberdeen in 1997 and retired from playing professional football in 2000.  Leighton also played in 91 international games for Scotland and earned selection for four World Cup squads (1982, 1986, 1990 and 1998). Martin Murphy Ferguson (born 21 December 1942) is a Scottish former football player, manager and scout.  Ferguson is the brother of former Manchester United manager Alex Ferguson.  He was Manchester United's chief European scout, and as such he was often sent to scout players in mainland Europe. The period from 1986, when Alex Ferguson was appointed as Manchester United manager, to 2013, when he announced his retirement from football, was one of the most successful in the club's history.  Ferguson joined the club from Aberdeen on the same day that Ron Atkinson was dismissed, and guided the club to a 12th-place finish in the league.  Despite a second-place finish in 1987–88, the club was back in 11th place the following season.  Reportedly on the verge of being dismissed, victory over Crystal Palace in the 1990 FA Cup Final replay (after a 3–3 draw) saved Ferguson's career.  The following season, Manchester United claimed their first Cup Winners' Cup title and competed in the 1991 European Super Cup, beating European Cup holders Red Star Belgrade 1–0 in the final at Old Trafford.  A second consecutive League Cup final appearance followed in 1992, in which the team beat Nottingham Forest 1–0 at Wembley Stadium.  In 1993, the club won its first league title since 1967, and a year later, for the first time since 1957, it won a second consecutive title – alongside the FA Cup – to complete the first "Double" in the club's history.
