Real Madrid forward Vinicius Jr said “La Liga belongs to racists” after he was again racially abused by opposition fans during a match.
The 22-year-old Brazil international was sent off for violent conduct in the 97th minute of the 1-0 La Liga defeat at Valencia after an altercation with Hugo Duro.
Earlier in the game, an incensed Vinicius attempted to bring Valencia fans to the referee’s attention.
“The championship that once belonged to Ronaldinho, Ronaldo, Cristiano and Messi today belongs to racists,” Vinicius wrote on Instagram.
“It wasn’t the first time, nor the second, nor the third. Racism is normal in La Liga. The competition thinks it’s normal, the federation does too and the opponents encourage it.
“A beautiful nation, which welcomed me and which I love, but which agreed to export the image of a racist country to the world. I’m sorry for the Spaniards who don’t agree, but today, in Brazil, Spain is known as a country of racists.
“And unfortunately, for everything that happens each week, I have no defence. I agree. But I am strong and I will go to the end against racists. Even if far from here.”
BBC Sport understands two fans who racially abused Vinicius have been identified and are expected to be given permanent stadium bans by Valencia.
Vinicius has been the target of racial abuse multiple times this season.
La Liga said in a statement it would investigate and take “appropriate legal action” if a hate crime was identified, calling on people to submit any relevant footage.
Writing on Twitter, La Liga president Javier Tebas said Vinicius twice did not turn up for a meeting to discuss what it “can do in cases of racism”.
“Before you criticise and slander La Liga you need to inform yourself properly,” Tebas said.
Vinicius criticised the post for targeting him instead of the “racists”, saying he wanted La Liga to take “actions and punishments”.
