Barcelona lost 1-0 to Real Sociedad on Sunday, suffering their second league defeat of the season. Robert Lewandowski had an early goal controversially disallowed for offside, sparking debate. Sheraldo Becker’s 33rd-minute strike secured the win for Sociedad, who held firm against a Barcelona side missing young star Lamine Yamal. Despite bringing on Dani Olmo in the second half, Barcelona struggled to create chances and failed to score for the first time this season.
