Real Madrid have filed a further complaint with the Spanish authorities over alleged racist abuse directed at striker Vinicius Junior during their 4-2 LaLiga win at Osasuna on Saturday.

Real had already filed a complaint with the Attorney General’s Office last week after footage on social media that appeared to show Atletico Madrid fans chanting racial abuse prior to their Champions League clash with Inter Milan.

In a statement, Real said they have updated their initial complaint, as well as filing a separate protest to the Spanish Football Federation’s disciplinary committee over the conduct of referee Juan Martinez Munuera.

Real allege Munuera filed a “negligent” referee’s report, adding: “The official omitted, in voluntary and deliberate fashion, the insults and humiliating chants directed towards our player on a repeated basis, despite his attention being drawn to them continually by our players as they were happening.

“Real Madrid once again condemns these violent attacks of racism, discrimination and hate and demands that measures finally be taken in order to eradicate the violence to which our player Vinicius Junior has been subjected.”
