Everton manager Roberto Martinez believes that it is time for the relevant governing bodies to take a "strong stand" against racism in football.
A new incident came to light following Manchester City's 2-1 victory over CSKA Moscow in the Champions League yesterday.
City midfielder Yaya Toure is alleged to have been subjected to monkey chants from CSKA fans during the match in Russia.
"It is a real shame," Martinez said in a press conference. "It is important for FIFA and the football authorities to do something about it and not just let it go or just accept it or brush it aside. It is time to make a strong stand on the issue and make sure it doesn't happen.
"We shouldn't see this happening season after season. We should be talking about a very good victory for a British club travelling away and fighting a good game against a Russian team."
City have lodged an official complaint to European governing body UEFA.
