Lionel Andrés "Leo" Messi[note 1] (Spanish pronunciation: [ljoˈnel anˈdɾes ˈmesi] ⓘ; born 24 June 1987) is an Argentine professional footballer who plays as a forward for and captains both Major League Soccer club Inter Miami and the Argentina national team. Widely regarded as one of the greatest players of all time, Messi set numerous records for individual accolades won throughout his professional footballing career such as eight Ballon d'Or awards and eight times being named the world's best player by FIFA.[note 2] He is the most decorated player in the history of professional football having won 45 team trophies,[note 3] including twelve Big Five league titles, four UEFA Champions Leagues, two Copa Américas, and one FIFA World Cup. Messi holds the records for most European Golden Shoes (6), most goals in a calendar year (91), most goals for a single club (672, with Barcelona), most goals (474), hat-tricks (36) and assists (192) in La Liga, most assists (18) and goal contributions (32) in the Copa América, most goal contributions (21) in the World Cup, most international appearances (191) and international goals (112) by a South American male, and the second-most in the latter category outright. A prolific goalscorer and creative playmaker, Messi has scored over 850 senior career goals for club and country.

Born in Rosario, Argentina, Messi relocated to Spain to join Barcelona at age 13, and made his competitive debut at age 17 in October 2004. He gradually established himself as an integral player for the club, and during his first uninterrupted season at age 22 in 2008–09 he helped Barcelona achieve the first treble in Spanish football. This resulted in Messi winning the first of four consecutive Ballons d'Or, and by the 2011–12 season he would set La Liga and European records for most goals in a season and establish himself as Barcelona's all-time top scorer. The following two seasons, he finished second for the Ballon d'Or behind Cristiano Ronaldo, his perceived career rival.
