Emanuel Mariano Insúa Zapata (born 10 April 1991) is an Argentine professional footballer who plays as a left back for Spanish Segunda División club Racing de Ferrol.

[2] In July 2012 he was loaned to fellow league team Godoy Cruz, appearing in 33 matches; he also scored his first professional goal for the club, netting the last in a 2–0 home win against Atlético Rafaela on 19 August.

On 23 August 2017, Insúa left Udinese Calcio after one season and a half, mostly spent playing as loanee first for Newell's Old Boys, then for Racing Avellaneda, and officially signed over to Super League club Panathinaikos, on a 3-year deal for an undisclosed fee.

On 24 February 2018, Insúa changed direction skillfully with a cheeky backheel before sending a superb curling shot with the outside of his left foot past a hopeless Nikos Melissas, sealing the score in a 2–0 home win game.

[10] On 6 April 2019, Insúa produced a magical goal as Panathinaikos moved to within five points of fifth-placed Aris after claiming a solid 2–0 home win over the Thessaloniki club at the Olympic Stadium.

The Argentine met Omri Altman’s low cross perfectly and lofted the ball up and over Aris goalkeeper Julián Cuesta and into the net in stylish fashion.
