Nicolás Gabriel Sánchez (born 4 February 1986) is an Argentine former professional footballer who played as a centre-back and manager.
Born in the Mataderos neighborhood of Buenos Aires, Sánchez began playing football as a midfielder in Boca Juniors' youth system.
He became a professional with Nueva Chicago, with whom he made his debut in the 2003–04 Argentine Primera División, on 26 June 2004 against Independente.
Nueva Chicago was relegated soon after, and Sánchez continued to be part of the club's first team during the next two seasons in the Primera B Nacional.
However, Sánchez struggled with injuries, missing almost a year with a broken bone in his foot, and in 2010, after River Plate re-appointed manager, Ángel Cappa, and Sánchez left the club for Godoy Cruz on a free transfer.
