Atletico Madrid's away defeat to Levante yesterday was marked by racial abuse towards an opposition player.
Midfielder Papakouli Diop said that Atletico fans made monkey chants in his direction as he prepared to take a corner.
Diop told Marca that "they called me a monkey so I turned around and imitated a monkey. I did the monkey dance to defuse the situation. I want the people to know what is happening."
The incident comes a week after a Villarreal fan threw a banana at Barcelona's Dani Alves, who picked it up and ate, sparking a viral internet campaign.
This incident will further ignite the debate over racism in Spain, which was sparked by the Alves incident and his comments on the "backwards" approach to racism in the country.
England legend Gary Lineker, who had a spell at Barcelona, took to Twitter to say that "Spanish football must face up to the fact that they have a serious racist problem. They can't continue to bury their heads in the sand."
Diop added to this, saying that "I'm tired of racism in football. It happens a lot. I don't know if it's racism or a lack of respect, but the monkey chants have to stop."
