Although Sevilla started the game much more potent than Barcelona, the away side broke the deadlock.
Their front three broke forward at an incredible pace, and Lewandowski’s shot was cleared off the line, but Raphinha headed in the rebound.
The Polish striker scored outstandingly as he controlled Kounde’s lofted pass on his chest and volleyed home past Bono.
Garcia made it 3-0 early in the second half from a well-worked corner routine that saw Kounde head the ball towards Garcia for an easy tap-in.
Barcelona could have won this by many more but Bono pulled off a few stunning saves and the attackers missed a few sitters.

GOALLLLLLL!!!!! 2-0 LEWANDOWSKI!!!!! Barcelona doubles their lead through sheer brilliance. Kounde plays a lofted ball into the box for Lewandowski. The striker controls the ball on his chest and hits it on the volley to beat Bono in goal. World-class finishing.
GOALLLL!!!!! 3-0 GARCIA!!!! Garcia taps the ball home to make it 3-0 to Barcelona. Raphinha crosses the ball to Kounde at the back post. Rather than going for goal, the defender heads the ball across the six-yard box for Garcia to finish quickly.
