Barcelona dropped points in La Liga for the first time this season, losing 2-1 at the Camp Nou to newly promoted Alaves.

“We worked very hard for this,” Mauricio Pellegrino, Alaves’s new coach, said. “I hope the team can keep growing and that this will help us going forward.” It was the club’s first win in Spain’s top flight since a 10-year run in the second and third divisions.

“We didn’t have our day,” Luis Enrique said. “We were imprecise, and they scored two goals on three shots. That is a good summary of the match.”
