Alaves beat Barcelona 1–0 as Ibrahim Yalatif Diabate’s goal in first-half stoppage time decided a match where the hosts defended deep and struck off their limited chances. Diabate finished from an Antonio Blanco Conde assist in the 45+1 minute and Alaves then protected the lead. Barcelona had 77% possession and eight shots but failed to record a shot on target, despite a wave of second-half substitutions.
