#1 Jupp Heynckes
Retired German manager Jupp Heynckes also left an indelible mark on football, after leading Bayern Munich to dominate European football in the 2012-13 season. The 73-year-old oversaw Bayern’s most successful season in the club’s history that year.
He led the club to win the Bundesliga in record fashion, after wrapping up the title by late February. Heynckes’ Bayern also swept aside all their rivals to emerge winners of the DFB Pokal.
In the Champions League, the Bavarians beat Barcelona 7-0 on aggregate – a game which went down as one of the worst defeats in the history of the Catalan club.
Heynckes and his Bayern side went on to complete the treble after defeating rivals Borussia Dortmund 2-1 in the final. The legendary German manager may be retired currently, but his legacy will go on, because it will take ages before any other manager achieves such a feat.
