Agustín Sebastián Cousillas (born 19 April 1990) is an Argentine footballer who plays for Chacarita Juniors as a goalkeeper.
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.[1] 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.[2]
On 27 June 2014 Cousillas moved abroad for the first time of his career, joining Málaga CF and being assigned to the reserves.[3]
Cousillas' father, Rubén, was also a footballer and a goalkeeper.
