Real Madrid went into the Clásico on 25 October unhappy with the appointments of Juan Martinez Munuera as referee and Javier Iglesias Villanueva on VAR.
Real Madrid's television channel aired a report before the Clasico at Spotify Camp Nou, alleging Barcelona receive more favourable refereeing treatment.
Appointments were reported for Wednesday's Champions League matches involving Como, Inter, Bayern Munich and Arsenal.
In the Saudi Roshn Pro League's tenth round, Saad Al-Kathiri said Al-Hilal should have had a 17th-minute penalty against Al-Hazm and VAR should have intervened.
