The match took place in the San Siro Stadium in Milan, Italy, where the visitors' supporters chanted racial slurs against the home team. According to a BBC report, Roma's captain Francesco Totti complained to the referee about the chants and later addressed the fans.
Stadium authorities made an announcement ordering fans to stop chanting before the game continued. The match's score was 0-0.
Even since a friendly match between Milan and Pro Patria was suspended over racist chants in January, FIFA -- soccer's world governing body -- has decided to take action against racism at games. They announced the formation of a new anti-racism task force in March.
