Ethan Mauricio Espinoza Martínez

Espinoza came through Colo-Colo's academy, playing in the Copa Libertadores Sub-20 with the club in both 2018 and 2020 before making his senior debut for the first team in 2020. He was called up to the Chile under-20 squad in May 2021, though a senior international cap has not followed.

What stands out in his career since is how rarely he has stayed put. After breaking through at Colo-Colo, he was loaned out in successive spells to AC Barnechea, Arturo Fernández Vial, Deportes La Serena and Santiago Wanderers, with the move to La Serena eventually turning from a loan into a permanent transfer. He returned to Colo-Colo before leaving once more in January 2026, this time on a permanent transfer to Deportes Concepción.

Espinoza has built his career largely away from Colo-Colo's first team despite being one of its own products, picking up experience across several Chilean clubs rather than establishing himself for long at any single one before this latest move.
