Sergio Leonel "Kun" Agüero was born on June 2, 1988, in Buenos Aires, Argentina. He was raised in a middle-class family as the second of seven siblings, not 33 as previously stated. His childhood was deeply influenced by Argentina’s football culture, and he started playing football at just five years old. His parents were highly supportive of his passion for the sport, fostering his early development in local youth teams.
At the age of nine, Agüero joined the youth system of Club Atlético Independiente, one of Argentina’s most historic clubs. He made his senior debut at the remarkable age of 15, becoming the youngest player in the club’s history to play in the Argentinian Primera División, breaking Diego Maradona's previous record. Within a year, he became a regular starter and scored 18 goals in domestic competition, signaling his potential as a top-tier striker.
Agüero's impressive performances at Independiente attracted attention from major clubs around the world. In 2006, Spanish club Atlético Madrid signed him for a reported transfer fee of approximately $30 million—one of the highest fees paid by the club at the time. His breakout season came in 2008, where he scored 19 La Liga goals, making him the league’s third-highest scorer that year. At just 19 years old, his goal-scoring versatility further elevated his international profile. In the following season, he reached a personal milestone with 20 goals, his highest tally in a calendar year while at the club. Despite dealing with injuries, he played a crucial role in helping Atlético qualify for the UEFA Champions League.
