The 24-year-old has already scored 11 goals in just 10 appearances for the Red Devils this season.
And his confidence was clear to see as he surged through on goal during his country's World Cup qualifier against Cyprus.
The Belgians were already 3-0 up, thanks to a brace from Chelsea’s Eden Hazard and another goal from brother Thorgan.
Lukaku – who had come on as a substitute just minutes earlier – managed to chase a hopeful pass as a Cypriot defender desperately tried to barge him off the ball.
But the imposing striker barely noticed the centre back and casually sent him crumpling to the ground with his strength before firing into the bottom left.
Lukaku has now scored 10 goals in seven for his country and is just six short of becoming their all-time leading goalscorer.
And fans were very impressed by his latest finish.
“Lukaku’s goal for Belgium last night sums his game up to an absolute T,” one wrote. “Pace, power and a clean finish. The man is a machine.”
Another added: “Lukaku is on fire and destroying centre-backs for fun.”
And a third commented: “Rom just rag dolls his defender completely here to bag his goal for Belgium.”
