Overview

• Real Sociedad struck first through Álvaro Odriozola just past the half-hour before Jules Koundé leveled with a first-half header from a corner.
• Lamine Yamal entered early in the second half and within about a minute set up Robert Lewandowski's winning header.
• Yamal later saw a goal disallowed for offside, and both teams hit the crossbar late on.
• The victory keeps Barcelona unbeaten on 19 points, one ahead of Real Madrid after seven matches.
• Hansi Flick coped without injured Raphinha by starting 17-year-old Dro as Barcelona now prepare to host PSG on Wednesday in the Champions League.
