Spanish giants Real Madrid have filed a complaint against the referee who took charge of Saturday’s game at Osasuna for omitting alleged racist abuse towards Vinicius Jr from his match report.
The club say the “insults and vexatious shouts” were “deliberately” not included by Juan Martinez Munuera.
Vinicius has suffered racist abuse on multiple occasions in Spain over the past three years.
Real have demanded “necessary measures be taken” to “eradicate” the abuse.
The 23-year-old scored twice in a 4-2 win that moved Real Madrid 10 points clear at the top of La Liga.
Los Blancos have also added the incident to a complaint initially filed to Spanish legal authorities on Friday over alleged racist insults towards Vinicius by Atletico Madrid and Barcelona fans.
A video on social media appears to show Atletico Madrid fans chanting a racist slur before their Champions League game with Inter Milan on Wednesday, while Real allege there were similar chants from Barcelona fans before their encounter against Napoli the previous day.
The Brazil international has endured numerous instances of racist abuse in recent seasons.
They include Real’s derby win away over Atletico in September 2022. Last June, four men were fined 60,001 euros (£51,700) and given a two-year stadium ban for hanging an effigy of Vinicius near Real’s training ground in January 2023.
On the same day, three other people were fined 5,000 euros (£4,300) and banned for one year for making racist gestures during Real’s game at Valencia last May.
