Real Madrid defender Pepe has criticised Barcelona for a perceived hounding of match officials when decisions go against them.

Jose Mourinho's side overcame their fierce arch-rivals 2-1 at Santiago Bernabeu on Saturday afternoon, and the Portuguese international admitted that he did not like the way Barca complained to the match officials after they were not awarded a penalty in the second half.

"I've seen Barcelona doing unusual things, like surrounding the referee at the end. It's not a polite image," he told reporters after the game.

"I didn't see Adriano's action [for the penalty claim] but it seems like he is the one looking for contact.

"The referee was perfect. After all, he could also have sent off Thiago [Alcantara], but he had control."

Barcelona goalkeeper Victor Valdes was sent off after the final whistle for an outburst aimed at referee Miguel Angel Perez Lasa.
