Lazio's Serie A clash against Napoli at Rome's Olympic Stadium was suspended for three minutes on Wednesday after racist chants were allegedly directed at Senegalese defender Kalidou Koulibaly.
Napoli centre-back Koulibalywas booed whenever he touched the ball and referee Massimiliano Irrati halted the game in the 68th minute.
The visitors were leading 2-0 at the time through goals from Gonzalo Higuain and Jose Callejon.
After consultations with the coaches and officials, Irrati resumed the game three minutes later with the final 22 minutes played out and the visitors holding on for a 2-0 win.
After the match Napoli coach Maurizio Sarri praised the referee for stopping the game, saying: "I have to compliment the match referee because the situation was becoming embarrassing," he told Mediaset Premium.
"The lads all felt sorry for Koulibaly. But I think he took it all in his stride because he is very intelligent, has a good head on his shoulders and was being helped by his team-mates.
"Though I do think the suspension did affect his focus."
However, Sarri's Lazio counterpart Stefano Pioli had a different view on the incident.
"I would not have stopped the match," he said. "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."
