Mali international attacker, Moussa Marega, was a victim of an alleged racist incident during a Portuguese league match on Sunday between his team, Porto and Vitoria Guimaraes, prompting him to walk off midway through the match despite many of his teammates attempting to stop him from leaving.
Marega left his team's 2-1 win at Vitoria Guimaraes in the 69th minute while pointing to the crowd and sticking his middle fingers to the stands.
He was also yellow-carded by the referee as he walked towards the tunnel visibly emotional.
Marega was born in France but plays for Mali and had previously played for Guimaraes on loan in 2016-17. He scored Porto's second goal of the night just before the incident.
In an Instagram post after the match, Marega said: "I would like to only say to those racist idiots in the stands, go f--- yourselves."
The 28-year-old also had scathing remarks for the game's referees, saying: "I appreciate the officials for not defending me and for giving me a yellow card for defending the color of my skin. I hope to never find you on the football pitch again. You're an embarrassment!"
The Portuguese league's organizing body, Liga Portugal, also came out to condemn the racist chants.
"Liga Portugal does not agree and never will with acts of racism, xenophobia or intolerance that jeopardize the dignity of footballers or any human beings," said a statement on the organization's website.
"Liga Portugal will do everything to ensure that this episode and all other racist incidents do not go unpunished.
"We believe this is a fight where your team's colors do not matter and everyone must come together to eradicate this scourge on the game."
Guimaraes also added that it would investigate the incident and act accordingly.
"[The club] will not fail to censor any and all manifestations of violence, racism or intolerance,'' it said.
"[The club] will verify what happened during the game played at Estadio D. Afonso Henriques, acting firmly and consequently, in full cooperation with the competent judicial entities.''
