Manchester City midfielder Yaya Toure says the abuse he has been subjected to on social media is "a disgrace". Police are investigating claims that Toure was racially abused on Twitter, only hours after he reactivated his account following a five-month absence.
"For me, it's a disgrace to be honest," Toure, 31, told BBC Sport.
"We need to do something to try to tell people those kinds of behaviour have to stop.
"I want those people to understand what they're doing is wrong."
Toure called on the football authorities to do more to combat the problem of racism in the game.
"I've been trying to say to [world governing body] Fifa that they are on the wrong way and what they are doing is not good," he said.
"To have such aggression in sport, I can't understand that," he told BBC World Service's John Bennett. "That's why I've been trying to fight it.
"Football doesn't have a colour. We're just people from all over the world trying to enjoy the game.
"I never see this in rugby, I never see that in tennis or anything else. I don't know where it's coming from.
"Sport is sport. Sport is not violence. Sport is not about being bad with people. Sport is about being healthy and proud of what you are doing."
He fears failure to stamp out online abuse will force other footballers to steer clear of social media.
"For me, it's OK because I have experience, but for young lads who will maybe go on Twitter and find that... first, they'll be afraid; second, they'll close their account," he said.
Asked if he found the abuse hurtful, Toure said: "To be honest with you, no, because I've been attacked like that for many years. I will never stop telling them they are wrong and have to change."
