Víctor Valdés increased his lead at the top of our chart after Barcelona clocked up a comfortable victory at Tenerife, although Casillas stays three behind him after a third clean sheet in a row. Aranzubia, Juan Pablo and Sergio Asenjo also kept their goals against columns to zero in their sides' respective wins, and Cristian Alvarez let in one as Espanyol beat Zaragoza, the keeper making his first league appearance this season in place of Cameroon's Kameni, who is taking part in the Africa Cup of Nations this month.
