Sulley Muntari says he will walk off the field again if subjected to further racism.
The Pescara player - once of Portsmouth - was sent off last week for leaving the field after claiming he was racially abused during a game with Cagliari.
His suspension was overturned but the 32-year-old believes racism is "everywhere and getting worse".
"I went through hell and was treated like a criminal," he told BBC Sport.
"I went off the field because it wasn't right for me to be on the field while I have been racially abused."
Initially booked for dissent, Muntari added: "If I had this problem today, tomorrow or the next game I would go off again."
Muntari hopes FIFA president Gianni Infantino is the man who can intervene.
"I think he is capable of doing something in a good way to fight racism. I want him to fight racism," he said.
"I never heard anything like that in England because I think they don't tolerate it. England is the example for the world. If a country doesn't tolerate it then it means you get rid of it."
