Having begun his career at Atlético Nacional, Emilio Aristizábal is currently with Fortaleza CEIF on a loan deal where he has become the team's leading goalscorer. His temporary transfer occurred before the 2024 second semester concluded. The player's father, Víctor Aristizábal, has voiced his displeasure with how Gustavo Fermani, Atlético Nacional's director of football, handled the exit. In a conversation with Felipe Muñoz, Víctor Aristizábal conveyed his opinion that his son should have stayed at the club, revealing he had learned Fermani was proposing Emilio to other teams two months prior to the tournament's end, a method he found improper. While there are calls from fans for Emilio's return to Atlético Nacional, the final say will belong to the sporting director and the coaching team. The player's loan agreement with Fortaleza concludes at the end of December, and it is reported that Emilio's intention is to head back to Atlético Nacional to compete for a place in the 2026 squad.
