Barcelona's hopes of reclaiming the Primera Liga title survived intact despite a nervy showing in their 1-0 victory at Valladolid.
Barcelona had plenty of chances to kill the game off but lacked precision in the final twenty minutes, with Xavi and Andres Iniesta both failing to score despite a handful of chances.
Striker Samuel Eto'o was more successful, starting and then coolly finishing the game's only goal after forty minutes.
