Kalidou Koulibaly was targeted with racist abuse in Napoli’s 1-0 defeat to Inter Milan on Wednesday.
The Senegal international was abused all game, with Carlo Ancelotti later claiming he heard monkey noises from the home fans inside the San Siro.
"We asked three times for some action to be taken, but the match continued,” Ancelotti said, per Goal.
“We keep being told play can be halted, but when? After four or five announcements?”
Koulibaly, who was sent off during the game, posted a defiant message on Twitter, writing: “I'm disappointed by the defeat, but above all at leaving my brothers.
“But I am proud of the colour of my skin. Proud to be French, Senegalese, Neapolitan: Man."
And he’s received support from his peers, with Cristiano Ronaldo showing support with an Instagram post.
Sadio Mane's message to Koulibaly
Koulibaly’s compatriot and Senegal teammate Sadio Mane has now sent a message to the centre-back.
Accompanied with an image of Koulibaly with the words: ‘say no to racism’ underneath, the Liverpool forward wrote: “I am bitter not to say bruised and dismayed by what you have experienced.
“But I know you well enough that these abominable acts will not reach you at all.
“We are proud of our race and we will continue to defend it as we defend the colours of our homeland.
“You reminded the world that identity does not compartmentalise.”
Well said, Sadio.
Mayor of Milan reacts
The recent incident shows that football still has a long way to go to completely eradicate racism.
It’s going to take high-profile figures to speak up and the Mayor of Milan, Giuseppe Sala, did so in the wake of the abuse suffered by Koulibaly.
“It was a shameful act against a respected athlete, who proudly bears the colour of his skin, and also, to a lesser degree, against the many people who go to the stadium to support their team and be with their friends,” Sala wrote on Facebook, per Eurosport.News Now - Sport News
