Good evening and welcome to Eurosport's LIVE coverage of the Spanish Liga fixture between Barcelona and Alaves. We'll bring you all the action as it happens at the Camp Nou. Kick off is at 20:00 GMT.

Firpo was offside! The Barcelona left back was fed a pass inside the penalty area. He got the shot away and the ball spun behind. But the flag was up for an offside against Firpo.

Ilaix isn't afraid to get on the ball. This time the teenager tries to prod through a pass to Puig, but the ball bounces through to Pacheco. Barcelona are giving him plenty possession!

Break for Alaves! This is where the danger is for Barcelona as Alaves come flying forward on the counter attack, but Perez shoots over when he might have done a bit better.

Pacheco was off his line! The Alaves goalkeeper made the strange decision to come off his line, he forced Messi wide, but then ended up in no man's land. Pacheco blocks twice from Messi.

Into the side netting! Trincao cuts inside off the right wing and gets the shot away, but he could only find the side netting. The Portuguese forwards wants to make a good impression!

Ilaix has been very involved in the early exchanges of this match. The 18-year-old is showing no fear and is sticking close by Messi in an attempt to play off the Argentine.

Griezmann with the chance! Things opened up for the Barcelona forward inside the box, Trincao bundled the ball to Griezmann, but his shot is blocked and the ball spins into the air!

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

Okay, here we go. We are about to get under way at the Camp Nou. Kick off is just moments away.

The two teams are out at the Camp Nou as the famous Barcelona anthem plays around the empty venue.

Joselu and Perez both start and both will give the Barcelona defence something to think about.

Not long until kick off at the Camp Nou. Make no mistake, Alaves have the ability to cause Barcelona problems despite their lowly position in the La Liga table at the moment.

Moriba starts! It's a proud moment for Ilaix Moriba who has been handed his first start for Barcelona this evening. Koeman is proving once again he's not afraid to throw in the youngsters!
