Sergio Leonel "Kun" Agüero del Castillo is an Argentine footballer who plays as a striker for Manchester City in England's Premier League and the Argentine national team. On 5 July 2003, he became the youngest player to debut in the Argentine Primera Division at 15 years and 35 days, breaking the record previously established by Diego Maradona in 1976.He plays with the shirt name Kun Aguero.

A prolific goalscorer, Aguero's playing style is characterised by agility, acceleration and strength, being described as "sharp and clever" by former Argentine player Osvaldo Ardiles; a view which is shared by his international captain Lionel Messi, who believes Aguero possesses "immense power, strength and an incredible work ethic." Combined with his close control, quick feet, dribbling skills, and strength to keep the ball, he has been described as "a menace in the box". Despite his ability, Aguero's playing time has often been limited by injuries throughout his career.
