Real Madrid forward Vinicius Jr. has called La Liga and Spain racist after being the target of racial slurs from the stands during his team's defeat at Valencia's Mestalla Stadium on Sunday.

The Brazilian pointed out the fans who were insulting him, leading to the match being stopped for 10 minutes, and then got into an altercation with Valencia's players that led to him being sent off in the second half.

"It was not the first time, nor the second, nor the third," Vinicius posted on Twitter after the game. "Racism is normal in La Liga. "The competition considers it normal, the federation considers it normal and the rivals encourage it."

"The championship that once belonged to Ronaldinho, Ronaldo, Cristiano (Ronaldo) and (Lionel) Messi today belongs to the racists.

"A beautiful nation, which welcomed me and which I love, but which accepted to export to the world the image of a racist country. I am sorry for those Spaniards who disagree but today, in Brazil, Spain is known as a country of racists.

"I am strong and I will go all the way against the racists. Even if it is far away from here."

La Liga will request all available images in order to investigate what took place in light of the incident.

"If any hate crime is identified, we will take the appropriate legal action," the league said in a statement.

La Liga president Javier Tebas responded to Vinicius' comments by asking him to be more informed about what can be done in cases of racism.

"We have tried to explain it to you, but you have not shown up for either of the two agreed dates that you requested yourself," he said on Twitter.

"Before you criticize and slander La Liga you need to inform yourself properly. Don't let yourself be manipulated and make sure you understand each other's competences and the work we have been doing together."

Brazil President Luiz Inacio Lula da Silva expressed his support for the player and called on FIFA, soccer's world governing body, to stop racism in the sport.

"I would like to express my solidarity with our Brazilian player, a poor boy who succeeded in life and is potentially becoming one of the best players in the world, certainly the best at Real Madrid. And he is attacked in every stadium he plays in," he told a news conference.

"I think it is important that FIFA, the Spanish league and leagues in other countries take real action, because we cannot allow fascism and racism to dominate football stadiums."

Real manager Carlo Ancelotti also spoke out against the incident on social media.

"Today has been a sad day at Mestalla, where a group of fans have shown their worst version," he wrote. "It is time to stop talking and act forcefully. Racism has no place in football or in society. NO TO RACISM ANYWHERE."

Vinicius' teammate and fellow Brazil international Eder Militao expressed his support for the forward.

"It's a disgrace," he said. "To suffer racism, to defend yourself and then be sent off trying to defend yourself! How long do we have to put up with this?"

Ednaldo Rodrigues, president of the Brazilian Football Confederation (CBF), also sent a message of support to the 22-year-old.

"How long are we going to experience, in the middle of the 21st century, episodes like the one we just witnessed, once again, in La Liga? There is no joy where there is racism," he said on social media.

The Brazilian Ministry of Racial Affairs also weighed in on Twitter.

"The Brazilian government will not tolerate racism either here or outside Brazil," the organization said, adding that it will notify the Spanish authorities and La Liga about what happened to Vinicius.

The Spanish league has previously lodged complaints of racist chanting or insults against Vinicius, the latest of which was a claim before a court in Mallorca after fans were filmed racially abusing the forward.

Spanish police are also investigating a possible hate crime against Vinicius after a mannequin wearing his No. 20 shirt was hung from a bridge outside Real Madrid's training ground in January.
