The 26-year-old ended a two-year stay at Old Trafford in the transfer window and secured a club-record £75million switch to Inter.
Lukaku has enjoyed a great start at the San Siro with two goals in his first two Serie A matches.
He has been away on international duty with the Belgium squad this past fortnight and scored in the 4-0 Euro 2020 qualification Group I win against Scotland at Hampden Park on Monday.
Lukaku has now broken his silence on his switch to Italy and revealed that part of his decision was because he no longer wanted to play his football in England.
However, the former Chelsea and Everton forward also claimed that the lure of linking up with Inter and their coach Antonio Conte was too strong to resist.
He told ESPN: "This group of players we have here is a special group. And we have the right leader in front of us to take us to the right places.
"Inter is an ambitious club. It wants to get back where it needs to be. I want to help them build something here. It's the right move for me.
"The guy [Conte] can make a team. It's already like the guys have been there for many, many years together, even the ones who just arrived. It's the strangest thing."
