Raphinha hit a brace to give Barcelona a narrow 2-0 win over Osasuna on Saturday and take them seven points clear at the top of La Liga.
The Brazilian winger broke the deadlock after 70 minutes with a fizzing strike from the edge of the box to earn Barca their seventh-straight top-flight win.
Second-place Real Madrid visit Alaves on Sunday, aiming to cut the gap on the champions back down to four points.
Barca lacked their usual sparkle but ground out their victory, keeping their first clean sheet in six matches across all competitions.
They also recorded a fifth victory in five games at their partially reopened Camp Nou home.
“(The win) has a lot of merit, they were well organised, it was hard to find a way through. With patience and a lot of possession, we finally did it,” Barca defender Gerard Martin told Movistar.
“A clean sheet gives stability to the team, and then the goals always come.”
