Lukaku admits to twice being subjected to vile attacks in the Czech Republic, and the victim of monkey chants earlier in the Serie A campaign at Cagliari is looking for the European footballing governing body to respond.
"I said this the last time I was with the Belgian national team, UEFA should do something to solve this problem because situations like this in a stadium are not right," Lukaku told Esporte Interativo, with translation from ESPN UK.
"During the match, it happened twice to me and it's not OK. It's 2019, there are many players from various nationalities in the teams and when people go to the stadium and behave wrongly, in my view, they are a negative example for children."
Lukaku scored once and assisted on both of Lautaro Martinez's goals, the first of which prompted abuse from some supporters in attendance.
"I hope UEFA now does something because all the stadium behaved like this after Lautaro's first goal and that's not good for the people watching the game," Lukaku added.
UEFA has been criticized in the past for lenient punishment in regards to racism in both club competition and international football. England's Raheem Sterling called on authorities to take "a proper stance" after being subjected to racist chants during a Euro 2020 qualifier in Bulgaria. UEFA ordered Bulgaria to play its next match behind closed doors and fined the nation's football federation €75,000.
