And the Belgian striker, who scored and assisted during the win, has told Uefa they have to act.
“I said it last time when I was with the national team,” Lukaku told Esporte Interativo. “Uefa now has to do something about it, because things like this in stadiums is not right.
“Today it happened twice with me and that is not right with people. We are in 2019, there are many players with many different nationalities in their teams.
“When there are people that for me are bad, at the stadium, that’s not a good example for the kids. I hope that Uefa now do something about it, because the whole stadium did it when Lautaro [Martinez] scored the first goal, and that’s not good for the people watching this game.”
Lukaku appeared to make a point in celebrating a goal later overturned by VAR, gesturing to spectators at the Sinobo Stadium in Prague.
That goal was ruled out and a penalty awarded for the home side, which was converted to level the game at 1-1.
But goals from Martinez and Lukaku secured Inter Milan the win and moved them level on points with Borussia Dortmund behind Barcelona in Group F.
