Santiago Simón

Simón started playing football at the age of four at Cooperativa Tortuguitas. He joined River Plate's academy in 2013, following a week-long trial. He spent seven years in their system, notably moving into the reserve squad in February 2020; debuting versus Banfield on 14 February. Nine months later, on 20 November, Simón was promoted into Marcelo Gallardo's senior squad for a Copa de la Liga Profesional match with the aforementioned Banfield. His debut subsequently arrived, with the winger replacing Cristian Ferreira for the final seventeen minutes of a 2–0 away win. On 16 August 2025, Simon joined Mexican club Toluca.

Simón represented Argentina at U17 level. After featuring in an October 2018 friendly against their United States counterparts, Simón was selected by Pablo Aimar for the 2019 South American U-17 Championship, which they won, and the subsequent 2019 FIFA U-17 World Cup; appearing a total of five times across both competitions.
