Barcelona suffers defeat in San Sebastian

Flick's team loses 1-0 to Real Sociedad

Ansu Fati misses penalty in second half

FC Barcelona suffered a disappointing 1-0 defeat to Real Sociedad in San Sebastian on Saturday. It was the Catalan club's first loss of the season and leaves them in second place in the La Liga standings, two points behind leaders Real Madrid.

The only goal of the game came in the first half, when Alexander Isak headed home a cross from Mikel Oyarzabal. Barcelona had several chances to equalize, but they were unable to find the back of the net. Ansu Fati missed a penalty in the second half, and Ousmane Dembele hit the post late on.

The defeat was a setback for Barcelona, who had won their previous four matches in all competitions. It also raised questions about the team's ability to challenge for the La Liga title this season.

Barcelona will be looking to bounce back when they face Real Betis at home next weekend.
