Real Sociedad boss Jagoba Arrasate has admitted his frustration following his side's goalless draw with Levante at the weekend.
The Basque outfit had a number of opportunities to take all three points from the La Liga clash in San Sebastian, but were guilty of missed chances.
"We played a good match and we had plenty of chances. We missed a lot of chances today – ones we usually put away," he told reporters at a press conference.
"It's not easy to play Levante – they're a good side and defend well. But we did good things and should have won. Now we just have to concentrate on the game against Barcelona on Wednesday.
"It's an important match for the club, but if we want to win we have to be more successful in front of goal."
Sociedad currently sit sixth in La Liga.
