AC Milan coach Massimiliano Allegri has called for racism to be stamped out of football after Kevin-Prince Boateng was subject of prejudiced chants during his side's match against Pro Patria at Stadio Carlo Speroni.
The encounter was abandoned midway through the first half when Rossoneri players decided to leave the pitch, after the 25-year-old kicked the ball toward the home supporters' stands after receiving abuse.
"We are disappointed and saddened by what has happened," the 45-year-old told reporters after the match.
