Lukaku scored 27 goals in an impressive debut campaign at Old Trafford but the 25-year-old has struggled to replicate that form this term.
But the 25-year-old ended his 12-match goalless streak for United at Southampton last weekend and then scored at Old Trafford for the first time since March in Saturday’s 4-1 win against Fulham – their first win in five league games.
When asked whether external scrutiny had weighed on him, Lukaku said: “No, no, not really.
“I think I just need to keep working hard. Me and the manager had good conversations in the last couple of days, where really he told me what he wanted from me.”
Lukaku also says he has been looking to lose muscle, gained at this summer’s World Cup where he scored four goals to help Belgium finish third.
“(I added) a little bit of muscle,” he added. “It was at the World Cup. I just felt great and I think I played great over there, and then when I came back it is a different type of style.
