A stunning treble from the mercurial Lionel Messi helped Barcelona to another big win, but Real Madrid lead the way in Spain.
Elsewhere on Saturday, Valencian maintained their grip on fourth spot and Villarreal clambered out of the drop zone.
Messi's hat-trick led Barcelona to a resounding 5-0 victory over Real Mallorca at Camp Nou.
The Argentina forward netted three times in 18 first half minutes as his side quickly took control of the game.
The second half brought a first senior goal for Isaac Cuenca and a superb late goal from Dani Alves to round off the scoring.
Emilio Nsue's handball allowed Messi to score from the spot in the 13th minute.
David Villa forced a fine save from Aouate before Barca doubled their lead in the 21st minute when Dani Alves' deep cross and Adriano's mishit across the face of goal presented Messi with a tap-in.
And he completed his hat-trick in sumptuous fashion on the half hour, tucking Dani Alves' cross calmly past Aouate with a first-time finish from the edge of the box.
Thiago headed wide early in the second half but it was soon 4-0 when the impressive Adriano threaded in Cuenca to open his account.
Messi headed wide from Dani Alves' deep cross but the latter added a fitting coat of gloss to the scoreline with a stunning fifth in stoppage time when his dipping 25-yard shot flicked in off the underside of the bar.
It was also Barca's eighth consecutive clean sheet in all competitions and their third 5-0 win in a home record in this season's Primera Division which reads played six, won five, drawn one, scored 26, conceded none.
Remarkably, taking Barca's home record into account, Real Madrid top the Spanish standings after they edged out Real Sociedad.
Jose Mourinho's side were far from their free-flowing best, but got the job done to clamber to the Primera Liga summit.
Argentine striker Gonzalo Higuain proved to the hero of the hour for Los Blancos on Saturday as his solitary strike was enough to see off plucky Sociedad.
He provided a clinical finish just nine minutes into the contest, calmly slotting past Claudio Bravo after being sprung clear inside the box.
Real were unable to add to the scoring in the remaining 81 minutes, but Mourinho knows it is points not performances that matter most.
Sofiane Feghouli scored his first two goals of the season to help Valencia to a routine 3-1 win over Getafe.
The Algerian midfielder put the hosts in front after only 12 minutes as his shot from the edge of the area bounced into the ground and looped over Miguel Angel Moya.
The visitors responded with a fine equaliser when Juan Valera's cross from the right was headed back across goal by Dani Guiza and expertly flicked in by Diego Castro.
However, Valencia were back in front within two minutes as Feghouli made the most of another ricochet in the Getafe area to side-foot the ball home, and the hosts wrapped up the three points when Artiz Aduriz claimed his first goal of the season with 15 minutes remaining.
Villarreal moved out of the relegation zone with a much-needed 2-0 win over Rayo Vallecano.
Bruno Soriano and Borja Valero scored either side of half-time, whilst Marcos Senna also had a first-half penalty saved.
Piti should have brought Rayo back into the game but shot wide moments after the second goal and the Madrid side had goalkeeper David Cobeno to thank for keeping the score down as he saved brilliantly from Hernan Perez in the final stages.
