The Cameroon international, who almost walked off the pitch at Real Zaragoza in February last year due to racist chants, claims continued abuse has made him determined to act by drawing both fans and his fellow players into taking a hard line on the issue.

For that reason, he, along with Patrick Vieira, has backed www.feelfootball.com's anti-racism campaign, which has launched a survey to encourage supporters to make their opinions known.

He told Feel Football: "If we experience this in football it means our society is rotten and that means we're in a dangerous situation.

"That's what we need to be fighting against as football is a small thing, but society - just imagine.

"I am treated first and foremost as a footballer, as Samuel Eto'o, but away from the cameras a black man is suffering from racism and nobody cares - that's the problem.

"Promises have been made for change, for sanctions to be enforced, but the first move needs to be made and it needs to be made by those who are being subjected to racism.

"Part of me hopes that one day someone will manage to walk off the pitch (in protest)."
