Real Madrid forward Vinicius Junior says "the happiness of a black Brazilian in Europe" is behind criticism of his goal celebrations.
Agent Pedro Bravo said during a Spanish television discussion on the 22-year-old that "in Spain, you have to respect rivals and stop playing the monkey", leading to accusations of racism.
Bravo has since apologised on Twitter, saying he misused a metaphor.
"Accept it, respect it. In any case, I will not stop!," added Vinicius.
The Brazil international, who has scored five goals in eight games for the European champions so far this season, pointed out that he was far from the first player to dance in celebration, listing other stars who do similar.
"Weeks ago, some people started to criticise my dancing. But the dancing is not mine alone," Vinicius said.
"They belong to Ronaldinho, Neymar, [Lucas] Paqueta, [Antoine] Griezmann, Joao Felix, Matheus Cunha... Brazilian funk singers and samba dancers, Latin reggaeton singers, Black Americans.
