Tottenham forward Richarlison believes racism will continue happening "every day and everywhere" unless punishment is handed out following his own experience of abuse during Brazil's friendly win over Tunisia in Paris on Tuesday.
A banana was thrown at the former Everton player in the 19th minute after he ran towards the corner flag to celebrate scoring his side's second goal in a 5-1 win at the Parc des Princes.
Footage showed Manchester United midfielder Fred kicking the banana away, while other objects were also thrown onto the pitch.
Translated from Portuguese, Richarlison posted on Twitter: "As long as they stay 'blah blah blah' and don't punish, it's going to continue like this, happening every day and everywhere. No time bro!"
The 25-year-old received plenty of messages of support on social media, including from former clubs America Mineiro and Fluminense.
Prior to the game, five-time world champions Brazil had posed for photographs with an anti-racism banner which read, 'Without our black players, we wouldn't have stars on our shirts'.
The Brazilian Football Federation (CBF) later issued a statement via Twitter condemning the abuse of Richarlison and calling for strong punishments.
It read: "After Brazil's second goal, a banana was thrown towards Richarlison. The CBF reinforces its stance against discrimination and vehemently repudiates yet another episode of racism in football.
"Whether on or off the field, attitudes like this cannot be tolerated."
CBF president Ednaldo Rodrigues added: "Once again, I come publicly to express my rejection. This time I saw it with my own eyes. This shocks us. We must always remember that we are all the same, regardless of colour, race or religion.
"The fight against racism is not a cause, but a fundamental (battle for) change to wipe this type of crime from the planet. I insist on saying that the punishments need to be more severe."
Richarlison's goal had put Brazil back ahead after Montassar Talbi cancelled out Raphinha's opener. Neymar added a penalty, Raphinha claimed his second and Pedro wrapped up the scoring after Tunisia had Dylan Bronn sent off.
Ferdinand said on his FIVE YouTube channel: "I'm not saying football can change or cure racism because I would be an idiot to think that.
Rio Ferdinand has called on football's authorities to do more to combat racism, noting that Richarlison having a banana thrown at him prompted a similar level of "vitriol" to his showboating at Nottingham Forest last month.
"Football can play a good part in highlighting issues and standing together, standing strong and standing unified to make the authorities and powers that be put things in place to protect people, but it ain't happening. It's disheartening.
"You've got your own kids waking up and saying: 'Dad, have you seen that banana thrown on the pitch at Richarlison?' It's madness.
"There was probably as much vitriol and hysteria on social media and in the media in general as there were with this banana incident, racism incident, as there was when Richarlison was doing kick-ups when he got smashed. Let that sink in. It is mad and crazy."
