Barcelona 5-1 Alaves
Francisco Trincao is denied a hat-trick on his first La Liga start by the flag. Lionel Messi slips the ball through to the Portuguese youngster, who fires home. But he was offside.
Barcelona 5-1 Alaves
Another slick Barca passing move but Lionel Messi's shot is straight at the keeper. Promising signs up front for Tuesday's PSG game.
Barcelona 5-1 Alaves
Barcelona have a quick attack, Lionel Messi tries to find fellow hat-trick hunter Francisco Trincao. He can't get past his defender and then Barca win the ball back but slow play down to training-game speed.
Barcelona 5-1 Alaves
Barcelona bring on Ousmane Dembele for fellow Frenchman Antoine Griezmann. Still time for more goals, you feel.
Junior Firpo
Wonderful. Lionel Messi scoops a ball over the top to Antoine Griezmann and he lays it on a plate for Junior Firpo to blast into the roof of the net from close range.
Barcelona 4-1 Alaves
That is the first time Barcelona have scored in consecutive minutes in La Liga for just over a year.
Ansu Fati netted in the 30th and 31st minute against Levante last February in a 2-1 win.
Barcelona 4-1 Alaves
So that's two goals from Francisco Trincao on his first La Liga start, and two from Lionel Messi on his 505th game in the Spanish top flight.
Lionel Messi
Wow. I was still writing the last goal entry when Lionel Messi scores Barcelona's fourth.
He picks the ball up, shuffles onto his left foot and curls the ball into the top corner from 25 yards.
Francisco Trincao
Lionel Messi ghosts in behind Alaves' defence and he's one on one with goalkeeper Fernando Pacheco, who has come to the edge of his box.
Pacheco saves but is then powerless to stop Francisco Trincao from shooting into an empty net.
Barcelona 2-1 Alaves
A good Alaves move is wasted because Edgar Méndez's cross is over everyone.
Barcelona 2-1 Alaves
Barcelona double change. Midfielder Miralem Pjanic and right-back Sergino Dest replace Frenkie de Jong and Oscar Mingueza.
Barcelona 2-1 Alaves
Lucas Perez almost gets in behind Barcelona's defence but his cross is booted behind for a corner by Samuel Umtiti.
The corner is too deep and it ends up back in midfield.

Antoine Griezmann pulls the ball back to Riqui Puig, but his shot is straight at a defender.

Barcelona 2-1 Alaves
Almost a team of the season from Barcelona.
Pedri plays the ball down the left for Junior Firpo. He pulls it back for Lionel Messi, who clips a first-time ball over the top. Antoine Griezmann watches it drop and cushions a volley just wide.
Barcelona 2-1 Alaves
Barcelona replace one 18-year-old midfielder with another. Ilaix Moriba, who got an assist on his La Liga debut, is off and the relatively experienced Pedri is on.
Barcelona 2-1 Alaves
Lionel Messi looks in the mood here. It's a nice passing move and the Barca captain flashes a shot just wide of the far post.
