Sergio Sánchez Ortega (born 3 April 1986 in Mataró, Barcelona, Catalonia) is a Spanish footballer who plays for Málaga CF in La Liga. He can operate as either a right or central defender.

Espanyol

A product of RCD Espanyol's youth system, Sánchez made his debut for the first team on 24 April 2005, playing 85 minutes from the bench in a 3–1 home win against Real Zaragoza (his sole appearance of that season).

In January 2007, he was loaned to second division's Real Madrid Castilla and, at the end of the season, which ended in relegation, was loaned again, to Racing de Santander in La Liga, appearing significantly as the side from Cantabria achieved a first ever UEFA Cup qualification.

In July 2008, Sánchez returned to Espanyol, scoring his first goal for the Catalan side in a 1–1 home draw with Getafe CF on 20 September. He played the entire season on the right flank, as the club eventually avoided relegation.

Sevilla

Sánchez agreed to join Sevilla FC in July 2009, in a four-year deal worth €4 million, with an additional one million being added if the Andalusians attained certain goals. On 1 January 2010, it was announced that he would be unable to play football again until 'rigorous tests' were carried out on his heart, after he complained of pains. His season outputs consisted of seven league games – helping Sevilla to the fourth place – and two in the domestic cup which the club won, both legs of the clash against lowly CF Atlético Ciudad (9–3 on aggregate).

On 18 January 2011, after more than one year out of football, Sánchez returned to active – he had already been an unused substitute the previous week against former side Espanyol – starting in a Spanish Cup match against Villarreal CF, and helping the title holders reach the semifinals after a 3–0 home win (6–3 on aggregate).

Málaga

On 23 June 2011, Sánchez left Sevilla and joined neighbours Málaga CF for €2.8 millions, signing a four-year contract. He made his debut for his new club on 25 September, appearing as a right back in a 0−0 away draw against Zaragoza.

On 3 January 2012, Sánchez opened the scoring in a Spanish Cup tie against Real Madrid, through a header, in an eventual 2−3 away loss (2–4 on aggregate).
