Barcelona were stunned in their visit to San Sebastián on Sunday night, falling to a 2–1 defeat against Real Sociedad to drop points in La Liga for the first time since late October.
Mikel Oyarzabal got the hosts in front despite Barcelona dominating the first half. The league-leaders answered through Marcus Rashford halfway into the second half but Gonçalo Guedes responded just a minute later to restore the lead with what turned out to be the match-winner.
