Lukaku joined Manchester United from Everton in the summertime for an preliminary charge of £75million.
The Belgian has began his Old Trafford occupation on fireplace, scoring 8 instances in as many appearances.

“Now he’s at Manchester United he’s began beautifully smartly.
“Sometimes the best way we talk about Lukaku is other to the best way we talk about Harry Kane or (Sergio) Aguero or different best strikers.
“It at all times feels as though other people need a little bit bit extra from Lukaku.
“I believe as a result of he got here via at Chelsea and used to be an enormous presence, it used to be like ‘he’s going to change Drogba, he’s going to be the brand new Drogba’ – he’s not anything like Drogba to me.
“Drogba might be guy of the fit in a recreation with out scoring, he may dominate centre-backs, dominate a complete again 4, run in channels, knocking other people out of the best way.
“He’s extra Ruud van Nistelrooy, extra Andy Cole however we predict one thing that I don’t suppose he relatively is.
“But for me I believe his goalscoring report is outstanding, I believe it’s going to be at Manchester United and it’s going to proceed to be so.
“But I believe that criticism has to stop as a result of his numbers are so excellent.”
