On 19 December 2009, Barcelona won a record 6th trophy for the a calendar year, using an extra-time goal to beat Estudiantes in the Club World Cup.
That year, Barcelona had already won La Liga, the Copa del Rey, the Supercopa de España, the UEFA Supercup, and the UEFA Champions League, matching Liverpool's haul of 5 trophies in 2001. The Champions League victory qualified them for the Club World Cup, which included the champions of 5 other confederations and the UAE's Al-Ahli, who qualified as hosts.
Both Barcelona and Estudiantes entered the competition at the quarterfinal stage, with the Catalan side beating Mexico's Atlante and the Argentinians defeating South Korean team Pohang Steelers to set up their meeting in the Final.
Although Barcelona were heavily favored, a driving header from center forward Mauro Boselli put Estudiantes ahead in the 37th-minute. Despite constant pressure from Barcelona, the underdogs held on and looked to have secured victory when, with one minute left, Barça pulled level with a header of their own from forward Pedro.
Lionel Messi, that year's Ballon d'Or winner, provided the deciding goal in extra time, receiving a long cross and slipping the ball under Estudiantes keeper Damien Albil in the 110th minute. Two days later, Messi was named the FIFA World Player of the Year.
