Piqué scored the only goal of the match for Barcelona as they beat Villarreal 1-0 on Saturday and extended their lead at the top of La Liga to eight points.
Valencia are now third, albeit 24 points behind the leaders, after a 2-4 victory at Getafe. Manu gave the home side an early lead before former Getafe striker Soldado knocked in four second half goals to put Valencia well on the road to victory.
Sardinero scored a late goal for Getafe but it wasn’t enough.
