Real Madrid have appealed against Uefa's decision to reject complaints about the behaviour of Barcelona players in their Champions League semi-final first leg.
Barca were accused of "unsportsmanlike behaviour" by Real but Uefa said there was "no common strategy to provoke".
Uefa will hear the appeal on 16 May.
Real face their own hearing on Friday over midfielder Pepe's red card and coach Jose Mourinho's sending off and post-match comments.
The initial was taken by the Uefa disciplinary panel on Monday.
In the bad-tempered match, which finished 2-0 to Barcelona, Barca's reserve keeper Jose Pinto received a red card for a confrontation as the teams left the pitch at half-time. Pepe was sent off for a tackle on Dani Alves and Mourinho was sent to the stands after protesting decisions on the touchline.
After the final whistle, the Real coach continued his complaints, suggesting in his post-match press conference that Barcelona were favourably treated by referees.
Barcelona claimed Mourinho had "crossed the line" with the remarks. Madrid responded, accusing Barca's players of "consistently feigned aggressions with the sole purpose of misleading the referee of the match".
The second leg on Tuesday ended in a 1-1 draw at Barcelona's Camp Nou stadium, allowing the Catalan side to advance to a meeting with Manchester United in the final in London on 28 May.
