Barcelona moved six points clear at the top of La Liga and warmed up for next week's 'Clasico' against champions Real Madrid by easing to a 4-0 win at home to Deportivo La Coruna with doubles from Luis Suarez and Paulinho.
Suarez slotted a generous cutback from Lionel Messi into an open goal in the 29th minute to deservedly put Barca ahead, while Brazil international Paulinho got the second in the 41st, tapping in on the rebound after Messi had hit the post.
Messi endured a frustrating night in front of goal and was unable to add to his 14 league goals for the season despite hitting the woodwork three times and also having a penalty saved by former youth team mate Ruben Martinez while the score was 3-0.
Suarez then scored his fourth goal in three league games by firing in a Sergi Roberto cross from inside the area two minutes into the second half and Paulinho completed the rout in the 75th, pouncing after Jordi Alba's shot had come off the post.
Barca hit the woodwork a total of five times in the game, while striker Paco Alcacer was taken off injured in the first half and will miss the 'Clasico' after being ruled out for three weeks.
Barca lead the Liga standings on 42 points, six ahead of Atletico Madrid in second and eight in front of third-placed Valencia.
They are 11 clear of Real, who have a game in hand after missing this weekend's action due to playing in the Club World Cup, beating Brazilian side Gremio 1-0 in Saturday's final.
Javi Calleja's Villarreal edged a close encounter at Celta Vigo to reclaim their place in the top six.
Pablo Fornals scored the only goal of the game in the 34th minute at Balaidos.
That ended a three-game losing streak across all competitions for the Yellow Submarine, with Celta six points away from both the bottom three and the European spots.
Bottom club Las Palmas staged a late comeback against Espanyol, but missed the chance to claim a remarkable victory via an injury-time penalty.
Gerard Moreno's first-half brace appeared to be consigning the hosts to a 12th league defeat of the season until a stirring finale.
Loic Remy pulled one back with nine minutes left and Jonathan Calleri levelled in the closing seconds but, when an injury-time spot-kick presented itself for Jonathan Viera, he missed.
Cristhian Stuani's fifth-minute goal was enough to give Girona their second straight LaLiga win over Getafe on Sunday.
Stuani met Johan Mojica's cross with a powerful header past visiting keeper Vicente Guaita to give his side an early lead.
The 1-0 victory was another blow for Getafe who had been held to a goalless home draw by Eibar in their previous match.
