Barca five clear as Valencia slip up
The champions took the lead in the 58th minute with a Bernardo Corradi strike that took a huge deflection off Aitor Ocio, but seven minutes later Julio Baptista grabbed the equaliser.
Each side had a player sent off before Carlos Aranda stole in at the far post for the winner eight minutes from time. Aranda then became the second Sevilla player to be red-carded but Valencia could find no way to avoid their first league defeat of the season.
