Mario Balotelli has warned he will walk off the pitch if he is racially abused while playing for Italy in Euro 2012.
The Manchester City striker was the victim of racism from the crowd during his time playing in Italy.
Balotelli insists he will not tolerate it in Poland and Ukraine amid fears problems may surface during the European Championships.
"If someone throws a banana at me in the street, I will go to prison because I will kill him. Racism is unacceptable to me, I cannot bear it," he said.
"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."
Balotelli also declared himself a genius and insisted he is misunderstood by others.
"I think I am a genius, but not a rebel," he added. "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."
