ATLETICO MADRID fans racially abused Vinicius Jr ahead of their clash against Real Madrid.
Crowds gathered outside the Wanda Metropolitano ahead of kick-off and began chanting.
But things turned ugly when some members of the fanbase began chanting the words: “You are a monkey, Vinicius you are a monkey”.
The vile behavior comes days after Vinicius was told to “respect rivals and stop playing the monkey” by Spanish agent Pedro Bravo after he celebrated scoring against Mallorca.
Bravo’s comments led to numerous accusations of racism which are currently being dealt with by Real Madrid.
An official club statement read: “Real Madrid C.F. condemns all types of racist and xenophobic language and behaviour in football, sport and life in general, such as the regrettable and unfortunate comments made against our player Vinicius Junior in the last few hours.
“Real Madrid would like to express its affection and support for Vinicius Junior, a player who regards football as an attitude towards life through joy, respect and sportsmanship.
“Football is the most global sport there is and should be a model of values and coexistence.
“The club has directed its legal services to take legal action against anyone who makes racist remarks towards our players.”
Following the incident Brazil legend Pele offered a message of support to his compatriot.
