Hello everyone. Welcome to live coverage of this La Liga opener between Barcelona and Real Sociedad.

FT Barcelona 5-1 Real Sociedad. Barca win. Barca cruise to a 5-1 victory over Real Sociedad in Tito Villanova's first game in charge.

Alves almost gets in on goal, but he is dealt with by de la Bella, who has had a good game despite the score.

Barca are just never satisfied, are they? They are pushing for a sixth now. The visitors just want to go home.

Iniesta was clouted during that move, but has got back to his feet.

Unbelievable football by Barca. Iniesta and Alves combine to find Messi, who nonchalently scoops the ball over Bravo and it drops just wide. Messi was offside, but what a move.

GOAL! Barcelona 5-1 Real Sociedad (David Villa). It's a fairytale return for Villa, who scores on his return. Villa plays the ball out to Iniesta, who cuts it back to the Spain striker, whose first-time left footed effort flies into the top corner from 8 yards.

Ansotegi pulls Messi back as the Argentine was running at goal. It's blatent, it's a yellow.

But at the other end, Vela is inches away from scoring on his Sociedad debut as he throws himself at a cross from the left, but just failing to make contact.

Villa's introduction has lifted the Camp Nou, who are obviously delighted to see the striker back. Plenty of nice touches for the former Valencia man here.

David Villa receives a huge ovation at the Camp Nou as he comes on for Pedro. He's back

Beautiful skill by Pique, who gets forward and backheels the ball to Pedro, who fires a low shot at Bravo. Sometimes you have to remind yourself that Pique is a centre-back.

Sociedad sub: Angel on, Castro off.

Messi takes a knock to the ankle after a late tackle by Illarramendi. He gingerly gets back to his feet.

Alves's crossing has been top quality tonight, and Real Sociedad are forced to head another hanging cross out for a corner.

But Messi's free-kick is into the wall.

Iniesta is fouled 20 yards from goal - and Messi is eyeing the free-kick.

Sociedad deserve credit for the fight they've shown to keep this down to four. The way Barca started this game, double figures looked possible.

Sociedad sub: Vela on, Elustondo off

Pique nods the resulting corner wide.

Bravo forced into another save as Xavi lets fly from 25 yards.
