Sevilla was held 1-1 at home by Barcelona in a match the hosts finished with 10 men after defender Jules Kounde was sent off with a direct red card for throwing the ball into an opponent's face.
Papu Gómez put Sevilla ahead in the 32nd minute as steady rain fell upon the Sánchez Pijuán field. Ronald Araújo headed in Ousmane Dembele's corner kick to equalise for Barcelona just before halftime.
The match was deadlocked in the 64th when Kounde lost his cool. After Barcelona defender Jordi Alba had twice bumped him in the back while disputing a ball going out of bounds, Kounde grabbed the ball and slung it into his face from close range. The referee did not hesitate to show him a red card.
