A reminder that we will bring you live text commentary of Real Madrid's game at Sevilla later. That match kicks-off at 19:30 GMT. Build-up starts at 19:00 GMT.

Boos around the Nou Camp as Barcelona head for the dressing room. They need to up their game if they are to win this.

Great chance for Villarreal after a mistake in the Barca defence. Samu Castillejo only needs to lift the ball over the advancing keeper to put the visitors ahead but opts to fire straight at Claudio Bravo, who saves.

So far so good for Villarreal, who are showing why they are fifth in the La Liga table. Barcelona are being made to work hard. First signs of frustration from the crowd is heard as half-time approaches.

It's getting a bit tetchy out there. Villarreal defender Mario Gaspar can count himself unfortunate to be booked after running across Neymar. The Barcelona player looked as though he made a meal of that.

Roberto Soldado has sight of the Barcelona net. Home defenders are backing off and the former Tottenham striker pulls the trigger 25 yards out. That's not a bad effort at all as the ball whistles narrowly wide.

A yellow brick wall on the edge of the Villarreal penalty area is doing a good job at frustrating the hosts. One thing's for sure, Barcelona are going to have to work hard to earn these three points. More cutting edge needed by the hosts.

Credit to Villarreal, They haven't come to the Nou Camp to defend. The trouble is they are leaving themselves badly exposed when they concede possession.

Surely it's only a matter of time before the European champions take the lead. A fine stop from Alphonse Areola leaves Andres Iniesta frustrated after a brilliant break. Barca are pouring forward now.

Barcelona are beginning to stamp their authority. And not before time. Villarreal's keeper makes a fine stop to prevent an own goal after a period of home pressure. Neymar slips a defender before forcing another save. Plenty of promise but no end product...yet.

That's more like it.

A cross by Luis Suarez is only half cleared and the ball falls to Dani Alves whose shot is heading for the net before Jonathan dos Santos deflects it behind for a corner.

Are Barca tired after their midweek Champions League exploits? Are they saving themselves for El Clasico? Almost 20 minutes in and they have yet to register a shot on target.

Another Villarreal break. Denis Suarez, the former Manchester City and Barcelona B midfielder, is at the heart of the move but it breaks down after a stray pass inside the home area. Shaky start by the hosts. Their opponents, in contrast, are sharp and alert.

Unusually quiet start by Barca. We've seen this before...and they have gone on to coast to victory.

You can't miss Villarreal. They're wearing their traditional bright yellow shirts and they are certainly not here to make up the numbers. The visitors have won six of their first 10 La Liga games and they carve up an early opening as the ball is fed to Roberto Soldado who looks to be clean through before an offside flag brings a promising move to an end.

Barcelona are bossing early possession but have been unable to test Villarreal's keeper in the opening exchanges. Luis Suarez is prodding and probing on the edge of the opposition penalty area and wins a free-kick after a foul by Victor Ruiz. It comes to nothing.

Will Barcelona make it four La Liga wins in a row before El Clasico? Can Villarreal record their first league win over Barca since March 2008? We're under way.

There's absolutely no sign of any rain or wind in Barcelona. In fact it's a sunny day with blue skies over the Nou Camp. Here come the teams...
