Real Madrid have filed a complaint against the referee who took charge of Saturday’s win at Osasuna for omitting alleged racist abuse towards forward Vinicius Jr from his match report.
The club say the “insults and vexatious shouts” were “deliberately” not included by Juan Martinez Munuera.
Osasuna have denied there were any racist chants from their fans.
Vinicius has been targeted by racist abuse on multiple occasions in Spain over the past three years.
Real have demanded “necessary measures be taken” to “eradicate” the abuse.
The Spanish Football Federation’s technical committee of referees has been contacted for comment.
Real said: “The referee voluntarily and deliberately omitted the insults and vexatious shouts directed repeatedly towards our player Vinicius Jr, despite these being insistently pointed out by our players at the very moment when they were taking place.
“Real Madrid once again condemns these violent attacks of racism, discrimination and hatred, and demands that the necessary measures be taken, once and for all, to eradicate the violence that our player Vinicius Junior has been suffering.”
The Brazil international has endured numerous instances of racist abuse in recent seasons.
