For sixteen years (1989 – 2004) the top flight of English football was won by either Manchester United or Arsenal save three seasons where Liverpool, Leeds United, and Blackburn brought home the silverware. The Red Devils and the Gunners achieved these sustained runs due in large part to their managers Sir Alex Ferguson and Arsene Wenger. Before Pep or José or Potter or Pochettino there was Ferguson and Wenger, two enigmatic, opinionated and highly-effective football minds literally inventing the role of the modern football manager.
