Champions League: Where went wrong for Barca?

Barcelona midfielder Xavi says his side were disappointed they did not take their "endless opportunities" against Arsenal in the Champions League, losing 2-1 to the Gunners in London.

The Spanish international believes the Blaugrana were superior to the English side, but failed to convert their dominance on the scoresheet.

"It was a shame because we felt we were superior to Arsenal," the 31-year-old told Marca post-match. "The result is worse than last season's, as we had a draw in that match, and now we have a loss.

"The team made significant errors, but played good football. All we lacked was the finishing touch.

"We didn't convert our endless opportunities. The match was up for the taking, but failed to win. The result was somewhat unfair.

"We may be disappointed, and know what we need to do in the return leg. We believe we can do well at the Nou Camp, and we are optimistic, but we respect Arsenal a lot," he concluded.
