Sevilla coach Julen Lopetegui admits they were outclassed by Barcelona.
Barca won 3-0 at Sevilla on Saturday.
Lopetegui lamented: "They have done us a lot of damage with the goals. Then the quality of Barcelona with the score in favor facilitated their transitions. We were 1-2 at the start of the second half... We did good things, although we have to correct that defensive weakness.
"You have to grow with the attitude of the boys, who were facing a complex situation."
On Isco, the coach added: “He's not at his best percentage, but he played a very interesting game, just like Rakitic and Lamela. There are positive things and we stick with them."
