FIFA president Sepp Blatter says he was "appalled" when he learned that AC Milan's match against Roma was suspended because of racist chanting.

Sunday's game was stopped for 97 seconds during the second half when visiting Roma supporters would not stop chanting at Milan players Mario Balotelli and Kevin-Prince Boateng.

Blatter adds that FIFA's taskforce against racism and discrimination is "serious about devising a unified approach for FIFA's 209 members."

Referee Gianluca Rocchi made the decision to suspend the match briefly after warnings issued over the stadium speaker system went unheeded. Roma captain Francesco Totti had also attempted to calm the fans to no avail.

The Italian-born Balotelli is the star forward of Italy's national squad.
