Neymar scored his first goal in La Liga and led Barcelona to beat Sociedad 4-1.

FC Barcelona hosted a Champion League team, Real Sociedad, at the Camp Nou in what promised to be a tight affair. In reality, however, it was as one-sided a league game can be with Barcelona racing to a three goal lead in the first half thanks to goals from Neymar, Lionel Messi and Sergio Busquets. Teams exchanged goals in the second half, with Alberto de la Bella scoring for the visitor, and Marc Bartra replying for Barcelona.

Barcelona maintained their absolute begin to their title defence when Neymar scored his first La Liga goal and Lionel Messi netted his seventh of the season in a 4-1 victory at home to Real Sociedad on Tuesday.

The champions made it six wins from six largely thanks to a scintillating first-half display at the Nou Camp, when Neymar bundled the ball over the line after five minutes and World Player of the Year Messi made it 2-0 with a diving header from the Brazilian's cross three minutes later.

Sergio Busquets scored a rare goal to make it 3-0 in the 23rd minute before Barca lost some of their intensity in the second half and Alberto de la Bella pulled one back for the visitors just after the hour.

Messi, whose goal was his seventh in five league appearances this term, then set up substitute Marc Bartra to score from close range 13 minutes from time and snuff out any hopes of a Sociedad fightback.

Barcelona lead La Liga with 18 points, three ahead of Atltico Madrid who host Osasuna later on Tuesday. Real Madrid are two points behind in third, and play at Elche upon Wednesday.
