Cagliari vowed to ban the supporters responsible for racially abusing Romelu Lukaku in Sunday's 2-1 defeat to Inter but rejected "silly stereotypes" about the behaviour of their fans.
Lukaku's second-half penalty secured Inter's victory, however, the match was marred by monkey chants coming from fans behind the goal as the striker prepared to take his kick.
"Cagliari Calcio firmly rejects what happened Sunday night at the Sardegna Arena during the game vs. Inter," the statement began.
"The club underlines - once again - its intention to identify, isolate and ban those ignorant individuals whose shameful actions and behaviours are completely against the values that Cagliari strongly promotes in all their initiatives. Every single day.
"Cagliari does not want to underplay what occurred, endorses the respectable moral values of its people from all the stadium sections, but firmly rejects the outrageous charge and silly stereotypes addressed to Cagliari supporters and the Sardinian people, which are absolutely unacceptable."
Lukaku released a statement earlier on Monday calling for greater action from social media and federation stakeholders, which Cagliari echoed.
"Full solidarity to Romelu Lukaku and even stronger commitment towards annihilating one of the worst plagues that affects football and our world in general," the statement continued.
"However, as we are aware that technology is not enough, we believe our commitment needs a real support by the rest of the football stakeholders; starting from all the true supporters, to all the stewards in the stands; from police and security agents, passing to media and as well through Lega Serie A and FIGC [Italian Football Federation].
"Cagliari is asking you all [for] solid help to win a battle that involves everyone. No one excluded."
