The former president of the Italian Football Association (FIGC) says more must be done to stamp down on racist behaviour following the incidents at the Stadio Olimpico on Wednesday night.
Giancarlo Abete, who stepped down from the role with the FIGC in June 2014, has praised referee Massimiliano Irrati for suspending a game for almost four minutes after Lazio supporters racially taunted Napoli's Kalidou Koulibaly.
Koulibaly also believes the official made the right call and showed "courage" in taking a stand.
Lazio have since been sanctioned with a partial stadium closure for their next two Serie A fixtures.
"We need to make a clear statement that this behaviour is not how we would like it to be," Abete told La Gazzetta dello Sport. "Suspending the game is an evaluation which must be made by the referee and I think overall everybody agrees that the referee was right, in view of what happened."
Suspending a game may not be the answer, though, according to the president of the Italian Olympic Committee, Giovanni Malago.
Malago questioned whether Lazio fans, who have been in a dispute with president Claudio Lotito for several years, may have been purposefully forcing the punishment to cause financial damage to the club.
With that in mind, Malago believes other measures may have to be adopted to ensure it is those who misbehave who end up paying.
"It seems to me to be a form of self-harm by a group of people who know exactly what automatic punishment their behaviour will draw," he said.
"I believe that they are not intentionally discriminatory or racist, but probably it is an absolutely unacceptable and unjustifiable way to protest against somebody, I don't know whether it is the team or the club."
Lazio will have a reduced capacity for their fixtures against Hellas Verona and Sassuolo, while they were also fined €50,000 for Wednesday's incidents.
