Anzhi Makhachkala defender Christopher Samba has labelled the fans of Zenit St Petersburg as 'no good and racist'.
A fans group of the club recently penned an open later protesting against buying black players, claiming their absence was 'part of the club's history'.
Samba has since slammed those responsible and says they are living in the dark ages, having also demanded no homosexual players.
"I'm not surprised. Everybody knows Zenit supporters are no good and racist," he told BBC Radio.
"They are living in another century. It's a sad day for Russian football. In this time we have different communities and countries that constitute teams.
"If they can't accept that then they are never going to make progress."
Samba said black players should not boycott Zenit games, adding the majority of fans would not share the views of the minority.
"Boycotting, why? Because fans make a statement saying they don't want black players? No. Black players should fight for the good ones – not the idiots," he said.
"It's really sad. It's slowing down the process of Russian football being a better league. I hope the Russian federation take the necessary steps to sanction it.
"The fact that a lot of players are going to Russia should be promoted. But if we're not welcome then it would be very difficult to change the mentality ahead of the World Cup."
