Emilio Aristizábal

Having started his footballing career in the academy run by his father, named Escuela Aristigol, at the age of five, Aristizábal was not initially eager to train, with his father stating that he would often be too tired from school. After settling, he would often train with players one or two years older than him, and began to attract the attention of professional side Atlético Nacional in 2019. Having undergone a two-month trial with the club in October and November 2019, he joined the club in January of the following year, undergoing pre-season with the club's youth team. Having progressed through the academy, continuing to play with players one year his senior, he made his unofficial debut in a 1–0 friendly loss to Millonarios on 8 July 2023. On 2 November of the same year, he made his official debut for the club; coming on as a late second-half substitution for Jefferson Duque, as Atlético Nacional went on to beat Deportivo Pereira on penalties in their Copa Colombia match. In January 2024, Aristizábal scored his first goal for Atlético Nacional; in the club's last pre-season friendly, he scored a goal from six yards after meeting Carlos Sierra's cross, as Atlético Nacional went on to draw 1–1 with Venezuelan opposition Caracas. On 17 February 2026, Aristizábal joined Major League Soccer club Toronto FC on loan for the 2026 season, with an option to make the transfer permanent.

Initially a winger while at the Escuela Aristigol, he transitioned into a striker during his development, the same position as his father.
