Manchester City and Italy striker Mario Balotelli has threatened to walk off the pitch if he is racially abused at Euro 2012, which kicks off next week.
Balotelli added he would "kill" anyone who dared throw a banana at him in the street.
In a recent Panorama programme, BBC revealed cases of racism and anti-Semitism in football grounds in host nations Poland and Ukraine.
The Panorama programme showed fans making Nazi salutes on the terraces, black players being taunted with monkey chants and a vicious assault on a group of Asian students.
"If [racism] does happen I would leave the pitch and go home," said Balotelli.
"Racism is unacceptable to me, I cannot bear it. We are in 2012, it can't happen.
The former Inter Milan striker was regularly the target of racist abuse when playing in Italy.
Former England captain Sol Campbell advised fans not to travel, suggesting they would be risking their lives if they did so.
Ukraine's Euro 2012 director Markian Lubkivsky said Campbell's remark were insolent.
