Both players have been charged after criticising ref Undiano Mallenco for his performance during their El Clasico defeat to Barcelona.
Ancelotti said: "Cristiano Ronaldo and Sergio Ramos didn't disrespect anyone. They expressed their opinion and I understand that. I prefer not to think only about referees who get things wrong and no more.
"We didn't have any luck, especially in Ramos' case. We will try to get the decision reversed and hopefully the Committee will revoke the unjust card. We didn't have a lot of luck with this referee in other games either."
