An Argentine international, Messi is both his country's highest appearance-maker and their all-time leading goalscorer. At youth level, he won the 2005 FIFA World Youth Championship, finishing the tournament with both the Golden Ball and Golden Shoe, and an Olympic gold medal at the 2008 Summer Olympics. His style of play as a diminutive, left-footed dribbler drew comparisons with his compatriot Diego Maradona, who described Messi as his successor. After his senior debut in August 2005, Messi became the youngest Argentine to play and score in a FIFA World Cup in 2006, and reached the final of the 2007 Copa América, where he was named young player of the tournament. As the squad's captain from August 2011, he led Argentina to three consecutive finals: the 2014 FIFA World Cup, for which he won the Golden Ball, and the 2015 and 2016 Copa América, winning the Golden Ball in the 2015 edition. After announcing his international retirement in 2016, he reversed his decision and led his country to qualification for the 2018 FIFA World Cup, a third-place finish at the 2019 Copa América, and won the 2021 Copa América, while winning the Golden Ball and Golden Boot award for the latter.
