Darío Esteban Osorio Osorio was born on 24 January 2004 in Hijuelas, in Chile's Valparaíso Region. He came through Universidad de Chile's academy after being identified as one of the country's outstanding left-footed prospects, and his rise was quick: by his late teens he was already playing senior football in Santiago, carrying the reputation of a winger able to decide matches from the right side.
His breakthrough at Universidad de Chile made him a symbol of the club's renewed academy value at a difficult institutional moment. Osorio's close control, willingness to shoot early and ability to beat full-backs in one-on-one situations attracted European attention before he had completed many full seasons in the Chilean Primera División, and in 2023 Midtjylland moved decisively to take him to Denmark.
At Midtjylland he has developed in a league that suits young attackers who need physical rhythm without losing technical freedom. He helped the club compete at the top end of the Danish Superliga and has become one of the most visible Chilean exports of his generation, regularly used as a right winger who can also move inside as a second striker or attacking midfielder.
For Chile he debuted as a teenager in the early 2020s and has remained part of the national team's transition away from the Alexis Sánchez-Arturo Vidal generation. He featured in the 2026 World Cup qualifying cycle and the Copa América period around it, and by 2026 he was one of La Roja's clearest attacking references in a squad trying to rebuild its speed and unpredictability.
Standing around 1.82 m, Osorio is a left-footed wide attacker whose game is built on sudden acceleration, an early shooting trigger and diagonal runs from the right channel. His profile invites comparison with a more direct Ángel Di María or, in a Chilean context, a taller and more vertical version of Mark González: a winger whose value lies in changing the rhythm of a match with one touch.
