FIFA President Sepp Blatter has warned players that running away from racism is not the right way to deal with the issue.

AC Milan midfielder Kevin-Prince Boateng and his teammates walked off the field after he was subjected to abuse during a recent friendly match with Pro Patria.

Many players, including Manchester United defender Rio Ferdinand and former Arsenal star Patrick Vieira, praised Boateng for standing up to the racists, but Blatter responded by insisting players should not leave the pitch.
