The 19-year old midfielder, who was part of Atletico Madridâ€™s youth academy between 2007 and 2009, joins the Impact from Primera A outfit Argentinos Juniors.
"He is a young player that has a lot of potential," said Impact sporting director Nick De Santis.
"We have been following him for over six months and I also had the chance to see him play in Argentina. He is a technically gifted player with a lot of raw talent.
â€œWe feel that with some time on the field training with our experienced players and coaches, his talent can be refined. He is a young developmental project with a big upside."
