Sandro Ramirez sent the visitors ahead early in the second half and although Raphinha hammered home an equaliser, Fabio Silva struck to claim three points and take his team up to 14th.

Barcelona still lead champions Real Madrid by four points but Los Blancos, who host Getafe on Sunday, have played two fewer games than Hansi Flick's team.

The Catalans have now gone three league games without a victory, after a run of 11 wins in 12 prior in the top flight.

Barcelona wore white shorts as part of their anniversary celebrations, as they used to back at the start of their history.

They held a gala in the city on Friday night to mark the occasion, having been founded on November 29, 1899, but came undone on Saturday afternoon.

The Catalans were able to name teenage starlet Lamine Yamal on the bench after recovering from an ankle problem.

Former Barcelona goalkeeper Jasper Cillessen made a solid save to deny Fermin Lopez in the opening stages, with Las Palmas showing enterprise on the counter-attack.

Barca defender Alejandro Balde was forced off with concussion in the first half after a clash with Sandro, to be replaced by Gerard Martin.

Las Palmas came close when Alberto Moleiro teed up Javi Munoz, who drilled wide, while Jules Kounde lashed an effort over at the other end.

Raphinha came closest to breaking the deadlock in the first half, scoring from an offside position, after Cillessen denied Pedri, and hitting the crossbar after being played through by Gavi.

Flick threw on Yamal at the break for Pablo Torre, hoping the winger would give Barca the advantage after an even first half.

Las Palmas took a surprise lead early in the second half when Kirian Rodriguez played in Ramirez, who drilled home from the edge of the box.

Raphinha hit back quickly for Barcelona with a thumping long-range effort, but Las Palmas were soon ahead again.

Silva ran onto Munoz's probing long ball and fired past Inaki Pena to restore the Canary Islanders' advantage with his fifth goal in eight league matches.

Cillessen saved well to deny Yamal as Barca sought a leveller and Viti made a brave block to thwart Pedri.

Las Palmas survived eight minutes of stoppage time, with Dutch stopper Cillessen again saving from Yamal and two defenders desperately scrambling to block a late Robert Lewandowski chance to lock in the visitors' victory.
