Mario Balotelli has vowed to walk off the pitch if he suffers from racially abused while playing for Italy at Euro 2012.
The Manchester City striker was speaking after a documentary raised fears of potential racism at the tournament in Ukraine and Poland.
"Racism is unacceptable to me, I cannot bear it," he told France Football.
"I hope there will not be a problem at the Euros because if it does happen I would straight away leave the pitch and go home.
"We are in 2012, it can't happen."
The 21-year-old was regularly a target of racist abuse while playing in Italy.
Balotelli also said he believes he is a genius and smarter than most people.
"I think I am a genius, but not a rebel," he said. "I have my life, my world, I do what I want, without annoying anyone.
"I believe I am more intelligent than the average person.
"The talent God gave me is beautiful and wonderful, but it is difficult because you are always facing other people keen to judge you.
"There are few people with such talent, so there are few able to judge what I am doing."
