Coach Hansi Flick was sent off for protesting a penalty decision and Barcelona was held at Real Betis to 2-2 in La Liga on Saturday.
Flick disagreed with the referee’s decision to grant a penalty following a video review when Betis forward Vitor Roque fell in the area following a brush with Frenkie de Jong.
Giovani Lo Celso converted the 66th-minute penalty to level the score after Robert Lewandowski put the visitors ahead in the 38th.
Substitute Ferran Torres scored from a pass by Lamine Yamal to put Barcelona back in front in the 82nd, but Assane Diao struck in injury time to secure the draw for Betis.
Barcelona has dropped points in four of the last five rounds. The league leader is five points ahead of Real Madrid, which has two games in hand.
