Good afternoon and welcome to Eurosport's LIVE coverage of the Spanish Liga fixture between Valencia and Barcelona. We'll bring you all the action as it happens at Mestalla. Kick off is at 15:00 GMT.

Valencia are currently struggling to get out from the back under intense pressure from the Barcelona press. However, the Catalans have yet to create their first scoring opportunity.

It's certainly true that Setien has made an immediate impact in the way Barcelona have played under him, but they struggled past Granada and Ibiza. Will they for it in the way of results?

That penalty kick came out of nowhere. Barcelona had been utterly dominant in the opening 10 minutes and then one defensive lapse allowed Valencia a shot at taking the lead.

The penalty kick from Gomez was at a good height for ter Stegen, but there was still a lot of power on the effort from the Valencia striker. That was a world class save from the German.

TER STEGEN SAVES! Barcelona survive! Gomez stepped up to the penalty spot, but the Barcelona goalkeeper pulls off a stunning save to keep the scores level! What a stop by ter Stegen! Exceptional!

Pique is shown a yellow card for bringing down Gaya inside the box. The Valencia players want the Barcelona defender to be sent off, but the referee believes a booking is enough.

PENALTY KICK TO VALENCIA! Gaya gets into the box far too easily and Pique comes across and wipes out the left back! The referee points to the spot!

Valencia beat Barcelona in the final of the Copa del Rey last season. That win was masterminded by Marcelino. His sacking at the start of the season was a very unpopular decision.

The initial signs are that Messi is playing in the False Nine position again. Ansu is out on the right side with Griezmann drifting to the left but still leaving plenty of space for Alba to gallop into.

Barcelona have started the match well here. As expected, they are controlling the majority of the ball. This is a hallmark of Setien's approach - he wants his side to see plenty of the possession.

Of course, Suarez is still out through injury for Barcelona and that means Ansu has come into the starting lineup. The teenager didn't have his best game against Granada last weekend.

This should be one of the best and most compelling fixtures in La Liga this weekend. Both teams will be targeting three points. How will Barcelona fare in this new system with this new approach?

The match is under way at Mestalla! It's Valencia against Barcelona in this La Liga fixture!

Okay, here we go. We are about to get started at Mestalla. Kick off in this one is just moments away!

Of course, Barcelona are in the midst of a title race with Real Madrid. The pressure is on them to establish a three-point lead ahead of Real Madrid's game tomorrow.

Not long until kick off at Mestalla this afternoon. A win for Valencia would put them on the brink of a top four place in La Liga.
