The bottom team Almeria won at home with 1–0 and took the first ever victory against the big club.
For Barcelona, it was only the second defeat in the league this season and the team’s 13-match unbeaten streak was broken.
Barcelona still leads La Liga by seven points over second-placed Real Madrid, but the team missed the chance to grab an almost unassailable lead in pursuit of its first league title since 2019. Real cruised to a 1-1 draw with Atletico Madrid on Saturday despite playing with a man more last half hour.
For Barcelona, the loss was the second major blow in a few days as Xavi Hernandez’s side crashed out of the Europa League earlier this week against Manchester United.
El Bilal Touré scored the winning goal after 24 minutes of play. The victory means that Almeira left the place as second jumbo and stepped over the relegation zone.
Barcelona face Real Madrid on Thursday in the first semi-final of the Copa del Rey at the Santiago Bernabeu.
