Our next Euro live text is tomorrow's Real Madrid v Valencia game at 21:15 BST. See you then.

FULL-TIME

Alaves 0-2 Barcelona

It's all over. Barcelona begin their La Liga season with a second consecutive 2-0 win.

Alaves 0-2 Barcelona

Gerard Pique, playing as centre forward for absolutely no reason, tries to find some space in the box and has a shot saved.

Alaves 0-2 Barcelona

Denis Suarez's shot is saved but no Barca player can turn home the rebound. Alaves have a short-lived counter-attack.

Alaves 0-2 Barcelona

Corner to Barcelona as Ivan Rakitic's shot is deflected over.

INJURY TIME

Alaves 0-2 Barcelona

Three minutes added on. Can Lionel Messi get his hat-trick? Can Paulinho get a touch?

SUBSTITUTION

Alaves 0-2 Barcelona

Barcelona bring on midfielder Paulinho for his debut, following his 40m euros move from Guangzhou Evergrande.

He replaces Andres Iniesta for the last couple of minutes.

Paulo Dybala has put Juventus 4-2 up at Genoa with his hat-trick goal. They had trailed 2-0 within seven minutes.

Alaves 0-2 Barcelona

HERE COMES PAULINHO.

Alaves 0-2 Barcelona

Lionel Messi takes the free-kick from about 35 yards out but instead of shooting he crosses, but fails to find a team-mate. Might as well have gone for his hat-trick.

A nice bit of skill from little Zidane, Enzo, to get away from some Barca players. The crowd enjoyed that.

Alaves 0-2 Barcelona

Barcelona are totally dominant, Lionel Messi is fouled to break up another attack.

SUBSTITUTION

Alaves 0-2 Barcelona

Zinedine Zidane's son, Enzo, comes on for Alaves. He wears Enzo on the back of his jersey and goes by Enzo Fernandez, his mother's maiden name. He replaces Mubarak Wakaso in midfield.

Christian Santos replaces Ruben Sobrino in the second pasrt of that double change.

Alaves 0-2 Barcelona

Lionel Messi dances into the area and Rodrigo Ely just gets a tackle in to deny him a shooting chance.

HITS THE WOODWORK

Alaves 0-2 Barcelona

Lionel Messi almost has his hat-trick. Barca are just constantly knocking on the door and the Argentine hits the crossbar with his 18-yard effort. Alaves just crying out for the full-time whistle.

SUBSTITUTION

Alaves 0-2 Barcelona

Gerard Deulofeu, who could find his place taken by Ousmane Dembele, has played quite well today. He's replaced by Denis Suarez for the final 19 minutes.

Alaves 0-2 Barcelona

Alaves have a free-kick but Oscar Romero's 30-yard effort is held by Marc-Andre ter Stegen.

Lionel Messi is only the second player from the top five European leagues to reach 350 (and now 351) goals for the same club, after Gerd Muller with Bayern Munich (365).

GOAL - Alaves 0-2 Barcelona

Lionel Messi

Alaves don't really deal with Jordi Alba's cross and the left-back is able to head the ball through to Lionel Messi, who guides a shot home. That's his 351st La Liga goal.

Alaves 0-1 Barcelona

Actually Jordi Alba is up again. It did appear painful though, it didn't look like an act. And here Alba is now flying down the left on the next move but his cross is cut out. Actually...

Alaves 0-1 Barcelona

Jordi Alba is down in agony. He almost makes it 2-0 as he half-volleys a first-time shot over, but he hurt his ankle in the landing as he made contact with an Alaves defender. I think his day might be over.

Alaves 0-1 Barcelona

Barcelona are just playing the ball around near the halfway line. And now they go back to keeper Marc-Andre ter Stegen and build again.

In Italy, Juan Cuadrado has now put Juventus 3-2 up after they battled back from 2-0 down.

SUBSTITUTION

Alaves 0-1 Barcelona

Barcelona striker Paco Alcacer, who had been getting ready to come on anyway, replaces Aleix Vidal, who was playing on the right wing.

GOAL - Alaves 0-1 Barcelona

Lionel Messi

Barcelona have the breakthrough. Gerard Deulofeu gives the ball to Lionel Messi, who wriggles free of his markers and then has a deflected shot which squirms past keeper Fernando Pacheco.

Alaves 0-0 Barcelona

Lionel Messi steps up for a 25-yard free-kick, but keeper Fernando Pacheco doesn't have to work hard to keep it out.

Alaves 0-0 Barcelona

Lionel Messi has a go from 20 yards but forgets to curl it and it's gone wide.

He has failed to score 10 of his 56 La Liga penalties, although that includes the one he passed to Luis Suarez.

Alaves 0-0 Barcelona

Alaves are immediately on the attack and Ibai squares it to Manu Garcia who is inches away from sliding it home. That's one of their best chances all day.

KICK-OFF

Alaves 0-0 Barcelona

One interesting thing to note is that three of Barcelona's back four have been booked - Sergi Roberto, Gerard Pique and Samuel Umtiti.

We are under way in the second half.

Pacheco joins the club

Alaves' Fernando Pacheco and former Athletic Bilbao netminder Gorka Iraizoz, now at Girona, are the only keepers to have saved at least one penalty by Cristiano Ronaldo and Lionel Messi in La Liga.

Andy White: Arguably the best three players in the world, Ronaldo, Messi and Neymar are not very good at penalties. All hail Le Tiss!

When these sides met here in the league least season, Barca won 6-0. Luis Suarez (injured today) scored twice and Neymar (now at PSG) scored half those goals.

.
.

Barcelona had 80% of the ball in the first half. They had 11 shots to five, seven shots on target to one - and one missed penalty to none...

HALF-TIME

Alaves 0-0 Barcelona

We are level at the break thanks to Lionel Messi's missed penalty.

INJURY TIME

Alaves 0-0 Barcelona

Lionel Messi plays the ball to Gerard Deulofeu but his shot is saved. Two minutes added on.

YELLOW CARD

Alaves 0-0 Barcelona

What a dope. Andres Iniesta crosses from deep and Gerard Pique sticks up his arm to keep the ball in play. Handball. Yellow card.

Alaves 0-0 Barcelona

Can Alaves see it through to half-time? Barcelona have a series of corners.

YELLOW CARD

Alaves 0-0 Barcelona

Barcelona defender Sergi Roberto is booked for chopping down Manu Garcia.

In Italy, Juventus are level at the break away to Genoa. Paulo Dybala scores a penalty to make it 2-2. They had trailed 2-0 before Dybala pulled one back.

MISSED PENALTY

Alaves 0-0 Barcelona

Lionel Messi misses a penalty, yet again in his career. I say he misses, but it's actually a fantastic save by Fernando Pacheco, who dived down to the right to tip Messi's kick away.

PENALTY TO BARCELONA

Alaves 0-0 Barcelona

Lionel Messi crosses the free-kick, and it goes past everyone. The referee has pointed to the spot. What's happened here? Well, Ely pulled down Gerard Pique. Fair decision, although the type that isn't punished most of the time.
