He spent most of his 20-year senior career with Cádiz (nine seasons overall, appearing in all three major levels of Spanish football), finishing it with Athletic Bilbao where he played three of his four La Liga campaigns, for a total of 44 matches.

After representing several clubs in the lower leagues, with an unassuming three-year second division spell at Deportivo Alavés, he spent nine years of his career at Cádiz CF, being the second level's Zamora in 2004–05 and first-choice throughout most of the following season's La Liga, as the Andalusians were immediately relegated back.

[2] In an away match against Real Betis on 15 March, he was hit by a bottle thrown by an opposing fan, with his team leading 2–1 and 20 minutes left; he needed six stitches to a wound just inches below the eye, and Athletic were later awarded the win by the Royal Spanish Football Federation.

His final appearance – on 15 May 2010 against Racing de Santander – set a record as the club's oldest player in the league, aged 39 years, 119 days.
