The attacking midfielder has responded to the center back's criticism, saying that the Blancos defender has overstepped the mark with his appraisal of the Blaugrana.
The Portugal international labelled Iniesta and his teammates 'theatrical' after the attacking midfielder called for a penalty in the high-profile encounter, and the Spaniard is not amused with Pepe's comments.
"Of course I am affected by what he said. Every person is entitled to have an opinion and say that a certain action was a penalty. However, it cannot go any further than that. There are boundaries," Iniesta told Onda Cero. "If a player speaks about you and your teammates like this, you feel offended.
"I'm not theatrical in any way, and neither are the other guys. These comments hurt because they are a personal attack."
Barcelona currently sits first in La Liga, holding an eight point lead over Real Madrid.
