The Italian Serie A match between Lazio and Napoli on Wednesday was suspended for around three minutes after home fans aimed racist abuse at visiting centre back Kalidou Koulibaly.

The game was halted in the 68th minute following repeated booing from pockets of home support whenever Napoli defender and Senegal international Koulibaly touched the ball.

Referee Massimiliano Irrati only decided to continue the game after consulting with coaches and officials and Napoli secured a 2-0 win with goals from Gonzalo Higuain and Jose Callejon to stay top of the standings.

“I would not have stopped the match,” Lazio manager Stefano Pioli told Premium Sport. “It was chanting from the minority, but I don’t think they were racist.

“We also have players of colour and they are treated well.” Napoli coach Maurizio Sarri said he was sorry about the chanting.

“Bravo to Irrati for stopping the match,” he said on Twitter.

Italian football has been plagued by racist incidents recently, notably in 2013 when AC Milan players Kevin-Prince Boateng and Mario Balotelli were the victims of offensive chanting in two separate matches.
