Ignacio Pérez Santamaría (born 24 June 1980), known as Nacho, is a Spanish retired professional footballer who played mainly as a left-back (he could also operate as a left midfielder).
He appeared in 220 La Liga games over nine seasons, totalling 13 goals for Málaga (two spells), Levante, Getafe and Betis. He added 124 matches and three goals in the Segunda División.
A product of Málaga CF's youth system, Nacho was born in Málaga, and he made his first-team debut on 23 February 2003 in a 1–1 La Liga home draw against RC Celta de Vigo.[1] He went on to play four seasons with the Andalusians, with a loan to Levante UD in the same league in between.
In July 2006, upon Málaga's top-division relegation, Nacho signed with Madrid's Getafe CF. Scarcely used during his second season, he would be loaned in January 2008 to Real Sociedad as the Basques ultimately failed to return from Segunda División, with the player appearing in 16 matches – 13 as a starter.
Nacho was loaned again for the 2008–09 campaign, rejoining former side Málaga.[2] Mainly used as a substitute, he scored his first goal in his second spell in a 3–1 away win over Real Valladolid on 22 February 2009,[3] helping them to finish eighth immediately after promoting.
On 28 August 2009, Nacho moved to Real Betis of the second tier on a three-year contract.[4] For most of his stint he was used as an attacking left-back,[5] and played 34 games in his second year as the Verdiblancos returned to the top division after two years.[6]
Nacho's father and uncle, respectively, José Ignacio and Juan Carlos, also played for Málaga. His brother Perico appeared for the club's reserves.[7]
