The 2009 Ballon d'Or, given to the best football player in the world as judged by an international panel of sports journalists, was awarded to Lionel Messi of FC Barcelona on 1 December 2009.

Messi won the award by a record margin, 240 points ahead of 2008 winner Cristiano Ronaldo. Xavi was the second Barcelona player in the top three, finishing a further 63 points behind Ronaldo. Messi's win made him the first Argentine-born player to win the award since Omar Sívori in 1961; however, Sívori had taken Italian citizenship by that time and is recognised to have won the Ballon d'Or as an Italian player.

Additionally, another player was nominated but received no votes: Karim Benzema (Lyon, Real Madrid).

The "Ballon d'Or", literally translated as "the golden ball" and often referred to as the European Footballer of the Year award, was an annual association football award. It was presented to the player who has been voted to have performed the best over the previous calendar year. The award was conceived by France Football's chief magazine writer Gabriel Hanot, who asked his colleagues to vote for the player of the year in Europe in 1956. The inaugural winner was Stanley Matthews of Blackpool.

Originally, journalists could only vote for European players at European clubs, meaning that players like Diego Maradona (who played in European football clubs but is not European) and Pelé (who neither played for a European club nor is European) were ineligible for the award. In 1995, there was a change in the rules to allow non-European players to be eligible for the award if they played for a European club. The first non-European to win after the rule change was Milan's George Weah in the same year. In 2007, any player in the world became eligible, and the number of journalists allowed to vote also increased; 96 journalists from around the world chose their top five players, as opposed to the 52 Europe-based journalists in 2006.

Lionel Andrés Messi (Spanish pronunciation: [ljoˈnel anˈdɾes ˈmesi], born 24 June 1987) is an Argentine footballer who plays in La Liga for FC Barcelona and is the captain of the Argentina national team, mainly as a forward.

By the age of 21, Messi had received Ballon d'Or and FIFA World Player of the Year nominations. The following year in 2009 he won both the Ballon d'Or and FIFA World Player of the Year, and won the inaugural FIFA Ballon d'Or in 2010 and 2011. He also won the 2010–11 UEFA Best Player in Europe Award. Messi is the fourth football player to win three Ballons d'Or, after Johan Cruyff, Michel Platini and Marco van Basten and the second player to win three consecutive Ballons d'Or, after Michel Platini. His playing style and small stature have drawn comparisons to Diego Maradona, who himself declared Messi as his "successor".

Messi has won five La Liga titles and three Champions League titles. In 2012, Messi made UEFA Champions League history by becoming the first player to score five goals in one match, in a 7–1 win against Bayer Leverkusen. With two goals in the next round against A.C. Milan, he matched José Altafini's record of 14 goals in a single UEFA Champions League/European Cup season. He also became the first player to top-score in four successive European Champion Clubs' Cup campaigns. He set the world record for most goals scored in a season during the 2011–12 season, with 73 goals.

Cristiano Ronaldo dos Santos Aveiro,OIH, (born 5 February 1985), commonly known as Cristiano Ronaldo, is a Portuguese footballer who plays as a winger or striker for Spanish La Liga club Real Madrid and is the captain of the Portuguese national team. Ronaldo became the most expensive footballer in history after moving from Manchester United to Real Madrid in a transfer worth £80 million (€93.9 million/$131.6 million). In addition, his contract with Real Madrid, in which he is paid €12 million per year, makes him one of the highest-paid footballers in the world, and his buyout clause is valued at €1 billion as per his contract.

Ronaldo began his career as a youth player for Andorinha, where he played for two years, before moving to C.D. Nacional. In 1997, he made a move to Portuguese giants Sporting Clube de Portugal. Ronaldo's precocious talent caught the attention of Manchester United manager Alex Ferguson, who signed him for £12.24 million (€15 million) in 2003. The following season, Ronaldo won his first club honour, the FA Cup. He also played at Euro 2004 with Portugal and scored his first international goal in the opening game of the tournament against Greece, in addition to helping Portugal reach the final. He was featured in the UEFA Euro All-Star Team of this competition.

Josep "Pep" Guardiola i Sala (Catalan pronunciation: [ʒuˈzɛb ɡwəɾðiˈɔɫə]; born 18 January 1971) is a Spanish football manager and former player. As a player, Guardiola played as a defensive midfielder and spent the majority of his playing career with FC Barcelona. He was part of Johan Cruyff's "dream team" that won Barcelona's first European Cup. He also played for Brescia and Roma in Italy; Al-Ahli in Qatar; and for Dorados de Sinaloa in Mexico while attending managing school. While playing in Italy, he served a four-month ban for a positive drug test although he was cleared of wrongdoing twice on appeal in 2009 before the Courts of Justice of the Italian Football Federation (FIGC) and the Federal Anti-Doping Courts of the Italian Olympic Committee (CONI). As an international, he played for Spain, and in friendly matches for Catalonia.

After retiring as a player, Guardiola became coach of FC Barcelona B. On 8 May 2008, Barcelona President Joan Laporta announced that Guardiola would succeed Frank Rijkaard as the first team manager. He signed his contract on 5 June 2008. In his first season as manager, Barcelona won the treble of La Liga, the Copa del Rey, and the Champions League. In doing so, Guardiola became the youngest UEFA Champions League-winning manager ever. The following season, Guardiola and Barcelona won the Supercopa de España, the UEFA Super Cup, and the FIFA Club World Cup, bringing the manager's tally to the maximum of six trophies in six competitions in one year, thus completing the first ever sextuple.
