A decade ago Sir Alex Ferguson stunned the football world by standing down as Manchester United boss after a glittering 26-and-a-half year reign.
After 1,500 games in charge, spanning three decades, Ferguson retired having won 13 Premier League titles, two Champions Leagues, five FA Cups and four League Cups.
The most successful British manager of all time left a void at Old Trafford that has yet to be filled – United have not won the Premier League or challenged for it in the 10 years since he stepped down.
