#1 2009/10 Season

Guardiola's Barcelona in 2009 were quite honestly ridiculous. The team was performing at unprecedented levels of sporting prowess, and no team stood a chance against Pep's juego de posicion.
Keeping the dressing room grounded despite their amazing success, Puyol acted as Guardiola's general in the dressing room, winning games and titles without leaving any room for complacency. He is currently the only captain in football history to win a Sextuple- consisting of La Liga, Champions League, Copa del Rey, UEFA Super Cup, Supercopa de Espana, and Club World Cup in a single season.
A truly perfect season all round, Guardiola and his Barcelona squad truly set new limits in the 2009 season, winning the first sextuple in football history and hitting almost impossible heights of sporting excellence, an achievement which is unlikely to be eclipsed any time soon.
