Barcelona made a strong statement about its intention of reclaiming the La Liga title, cruising to a 5-1 win over Real Sociedad at Camp Nou on Sunday.
The Catalans surrendered the title to Real Madrid last term, but Sunday's dismantling of Real Sociedad could be a sign of things to come under new manager Tito Vilanova, who replaced Pep Guardiola over the summer.
Carles Puyol put the home side in front in atypical Barcelona fashion, nodding home a corner kick from close range in just the fourth minute.
The lead did not last long as Gonzalo Castro broke free in behind the Barcelona defense and hammered an equalizer into the roof of the net five minutes later.
But the Catalans seized control of the match through their talisman as Lionel Messi produced two goals in the span of five minutes.
The go-ahead goal came in the 11th minute when Messi turned through traffic and uncorked a left-footed shot that needed a slight deflection to get past Sociedad goalkeeper Claudio Bravo.
Messi added another in the 16th minute, poking a bouncing ball past Bravo at the near post.
Barcelona was not finished scoring as Pedro capped some exquisite combination play around the box by slotting Cristian Tello's cross past Bravo on the volley four minutes before halftime.
The night was capped with a goal from David Villa, who made a triumphant return to the pitch after a lengthy injury layoff.
Villa dished the ball off to Andres Iniesta only to fire the nifty return pass past Bravo and into the back of the net six minutes from time.
