"I was expecting 70,000 or 80,000 cules here but it wasn't like that," Xavi told reporters, as per Goal.
"The club is checking what happened."
Barcelona President Joan Laporta echoed Xavi's centiments and revealed there will be sanctions.
"What happened in the stands was shameful and undignified. As a cule, I felt ashamed. I will take measures," Laporta told Mundo Deportivo.
