Real Madrid chief Miguel Pardreza has hinted at anger over Pepe's suspension after their draw with Villarreal.
The Real defender was banned for two games after abusing the match officials following the final whistle.
"Pepe has been rightly suspended on occasion, but this time he was booked after being assaulted. That also worries us. Players are subjected to great pressure and some of their reactions are understandable. We simply wish to be able to fight in the same conditions as every other team. We want all actions to be assessed the same way," said Pardreza.
