Barcelona go into the brief Spanish winter break on top of La Liga after a glittering show from Lionel Messi helped the defending champions beat Alaves 4-1.
Real Madrid, who drew 0-0 at Camp Nou in the midweek Clasico, can draw level top on 39 points but behind on goal difference if they win at home to Atletico Bilbao on Sunday.
Seville are assured third place over Christmas on 34 points after their 2-0 win at Real Mallorca.
France World Cup winner Antoine Griezmann put Barca ahead on Saturday with a lovely snap-shot from outside the area after a slick exchange with Messi on 14 minutes.
"I needed to score a goal before the holidays, now I can go into them happy with myself," said Griezmann who has scored just seven goals since his summer move.
"We have a great team with some of the best players around and when we don't click, well, there's always Messi."
