LALIGA has sent warning to fans who are planning a 'hate campaign' directed at Vinicius Junior ahead of the Madrid derby on Sunday evening.
The Real Madrid star has been on the receiving end of some abuse from supporters, including racial abuse.
Earlier this week, one supporter was sentenced to one-year in prison and given a three-year stadium after being found guilty of racially abusing Vinicius and Samuel Chukwueze back in 2023.

According to ESPN, there have been a few fans on social claiming they will wear masks at the Wanda Metropolitano, so they won't be recognised when making the racist chants.
The league have since put out a statement warning supporters about their conduct, threatening that arrests will be made.
"LaLiga wishes to announce that it will proceed to formally report and request the immediate arrest of the instigators behind a hate campaign seeking to promote racist and derogatory acts at the upcoming match between Atlético de Madrid and Real Madrid," the league said in a statement.
"The aforementioned campaign constitutes the crime of incitement to hatred, as clearly defined in the Penal Code. LaLiga vigorously condemns these actions that -- directly or indirectly -- encourage, promote and incite hatred against an individual, in this case, the player Vinícius Jr., because of his race.
"These actions also involve the aggravating circumstances outlined in sections 3 and 4 of Article 510 of the Penal Code, as 'the acts are such to disturb public peace.' LaLiga will not tolerate such behaviour under any circumstances."
