Romelu Lukaku was subjected to monkey chants from the crowd during Inter Milan's 2-1 Serie A victory over Cagliari on Sunday.
The chants could be heard before and after the striker scored a penalty to win the game in his second appearance for the club.
The on-loan Manchester United player looked towards the Cagliari supporters after dispatching his spot-kick in the 72nd minute.
Former Juventus striker Moise Kean, as well as midfielder Blaise Matuidi, were subjected to racist chanting from Cagliari supporters during a Serie A clash last April.
The league's disciplinary panel later decided not to take action against the club.
Inter Milan, Cagliari and Serie A have yet to make any comment following the incident.

Italian football must start deducting points from the teams that their fans show no respect to the players, world wide soccer is the major intertainment,if other people start abusing our intertainers its high time such fans and the club must pay price so that they respect themselves.
