Atletico Madrid supporters chanted racist abuse about Real Madrid player Vinicius as they entered the club’s Civitas Metropolitano stadium on Sunday night ahead of the city derby.
‘Vinicius is a monkey’ chanted a group of Atletico supporters as they waited to enter the stadium.
The disgraceful scenes came two days after Real Madrid issued a statement condemning racist abuse aimed at the Brazilian.
The storm has been brewing all week.
Last weekend Vinicius was criticised for doing a dance after scoring against Mallorca at the Santiago Bernabeu.
He responded by calling out members of the Mallorca bench for calling out to their players for them to kick him.
This opened a debate about whether it was disrespectful or not for a player to dance after scoring and then when the racists began to wade in.
There were comments on a late night Spanish football show from football agent Pedro Bravo that if Vinicius wanted to dance a samba when he scored he should return to Brazil.
He then said: ‘He should be respectful instead of acting like a monkey’.
Real Madrid responded with their statement although they did not name the show where the comments were aired.
Atletico Madrid then unintentionally added to the tension ahead of the fixture. He was asked what would happen at the Metropolitano if Vinicius celebrated with a dance and he said: ‘there will be trouble’.
Real Madrid went into the derby having won all eight of their games in all competitions this season and knew they would go eight clear of their neighbours if they could win the game.
Meanwhile, Atletico Madrid put out a tweet prior to the game urging supporters to support the club with ‘passion’ but to show ‘respect’ to their opponents.
‘Countdown to the derby. Support Atleti with passion and respect to the rival!’ the club wrote on social media.
