Juan Ignacio Sills

Formed in Vélez Sársfield's youth divisions, Sills joined Costa Rican Primera División club LD Alajuelense on loan in 2008, before making any first team appearance with Vélez. He returned to his club in 2009. Sills did his first pre-season training with Vélez' first team during July 2010. However, he suffered a knee cruciate ligament injury that made him miss the entire 2010 Apertura tournament. For the first half of 2012, Sills played on loan for Instituto in the Primera B Nacional (Argentine second division), where he started in 21 games in his team's third-place finish. However, his team lost the promotion playoff to San Lorenzo and therefore could not achieve promotion to the Primera División. Upon his return to Vélez, he was part of the squad that won both the 2012 Inicial and 2012–13 Superfinal. Sills then went on to play for Universidad de Chile and Olimpo. In 2023, he played for Deportes Copiapó.
