Agustín Cousillas

Born in Roque Pérez, Buenos Aires province, Cousillas graduated from local Tigre, and was promoted to the first team in 2011. However, he acted only as a backup to Daniel Islas and Javier García. Islas subsequently left the club in the 2011 summer, but Cousillas remained behind García and new signing Damián Albil. On 2 December 2012 he played his first match as a professional, replacing Albil in a 0–1 loss at Belgrano. He was handed his first start on 6 March of the following year, in a 1–0 home win against Palmeiras for the year's Copa Libertadores. On 27 June 2014 Cousillas moved abroad for the first time of his career, joining Málaga CF and being assigned to the reserves.

Cousillas' father, Rubén, was also a footballer and a goalkeeper.
