Racism reared its ugly head again in Italy, where Lukaku was racially abused during Inter's 2-1 win away to Cagliari at Sardegna Arena on Sunday.
The incident, which came as Lukaku stepped up to convert a second-half penalty, sparked widespread condemnation of Cagliari – whose fans were also previously involved in racist chants directed at Pescara's Sulley Muntari (2017), Juventus midfielder Blaise Matuidi (2018) and former Juve forward Moise Kean (2019).

It begins with the words “we’re really sorry you thought what happened in Cagliari was racist.”
Anyone still wonder why I’m proud to never have set foot there?
Amid growing calls for Italian authorities to crack down on racism and Cagliari, Giulini told Radio Popolare: "We're trying to work in a serious way, through the awareness of our stewards who will have to report people to DIGOS [a law enforcement agency].
"It's not easy to lipread with technology: we'll also ask the decent fans for help, that is 99.9 per cent of Cagliari supporters.
"Fighting ignorance is difficult, so we can only raise awareness. This incident has caused huge anger and frustration in us for all the initiatives we're carrying out. We were the first to introduce a school for young fans.
"Cagliari isn't a racist city at all. I'm so sorry that this image of us has also gone abroad. I hope we aren't banned. Closing curvas isn't the answer: as I said before, stewards must be made aware.
"I won't rule out, however, that any of my stewards saw something or a camera identified someone chanting. Once they're recognised, these people could be denied entry if they try to re-enter the stadium."
"You have to stop games because otherwise we won't go anywhere," the Italy international told Rai Sport.
"I know it's a big step to take, but we have to do it because otherwise those 4-5 stupid people will always be there.
"Lukaku's appeal was right. It's up to us players to show we can be role models for all ages. We carry great influence. If it starts with us, that's a good thing."
