Good evening and welcome to Eurosport's LIVE coverage of the Spanish Liga clash between Alaves and Barcelona. We'll bring you all the action as it happens. Kick off is at 5.15pm.

Deulofeu arrived from Everton this summer, and while he isn't going to set La Liga on fire this season, he has shown enough to suggest he will be a good enough option for Barca.

Barcelona have started the match on top, but that last opportunity just illustrates how vulnerable they are at the back. Alaves will get chances in this match. That won't be their last one.

HOW DID HE MISS?! That should have been the opener from Sobrino. The cross was played to the back post, where it looked certain that the Alaves man who turn it home, but he stuck it past the post.

Messi has been given a completely free role by Valverde in this Barcelona team. It's the kind of role he played for Guardiola back in the day. Refreshing to see him back there again.

MESSI TAKES AIM! That's the first sight of goal from the Barcelona number 10, but it was simple enough for the Alaves goalkeeper, with Pacheco getting behind the effort. It was right at him.

And so Messi starts up front as something of a 'false nine' with help from Deulofeu. The former AC Milan and Everton man was actually rather impressive against Betis last week.

Suarez is still out injured for Barcelona. He picked up a knock in the Super Copa defeat to Real Madrid a couple weeks ago. He is expected to be out for a few more matches.

Of course, Barcelona have been in the news again this week, signin Dembele from Borussia Dortmund for a sensational £95 million. He is now the second most expensive player ever.

So Barcelona started their league campaign last week with a comfortable win over Real Betis at Camp Nou. This could be a more challeging test for Valverde's men on the road.

The match is under way! It's Alaves against Barcelona in La Liga.
