It's emerged in the last 24 hours that Lukaku is upset with Zlatan Ibrahimovic for forcing him out of position - despite no instructions from the United coaching staff, including manager Jose Mourinho.
Cavani found himself in a similar situation working with Ibrahimovic in Paris and recalled: "When I arrived, I had other ideas in mind.
"But the conditions of the team were as they were. I had to play on the wings and adapt.
"Today, I have the opportunity to occupy this place that I wanted so much."
