Milton Casco

In August 2015, Casco was close to a €2.5 million move to French club Olympique de Marseille. The transfer fell through when compatriot Marcelo Bielsa unexpectedly resigned as the Ligue 1 team's manager.

On 9 September 2015, Casco signed a three-year contract with CA River Plate, with the Buenos Aires-based club purchasing 85% of his economic rights for $3 million. He made his debut four days later in the Superclásico against arch-rivals Boca Juniors, a 1–0 home loss.

On 27 May, uncapped Casco was selected by coach Gerardo Martino for the 2015 Copa América in Chile. He made his debut in a preparation friendly on 7 June at the Estadio San Juan del Bicentenario, filling in for Facundo Roncaglia for the final 29 minutes of a 5–0 win over Bolivia; however, he did not feature in the tournament, in which his country lost to the hosts in the final.

Absent from the national team since the 2015 tournament, Casco was a surprise inclusion for the 2019 Copa América in Brazil, with Lionel Scaloni picking him ahead of Gabriel Mercado. He played one game of a third-place finish, the 1–1 group draw with Paraguay at the Mineirão.

Born in María Grande, Entre Ríos Province, Casco began his professional career with Gimnasia y Esgrima La Plata of the Argentine Primera División in 2009. In July 2012 he signed for Newell's Old Boys under manager Gerardo Martino, who bought 50% of his economic rights.

Milton Óscar Casco (born 11 April 1988) is an Argentine professional footballer who plays as left back for River Plate and the Argentina national team.
