Lukaku, who initially moved to Stamford Bridge at the age of 17 from Belgium’s Anderlecht side in 2011, returns to Chelsea on a five-year contract.
The costs of the Belgian top scorer exceed the £ 75.8million paid for Kai Havertz last summer.
“I am happy and blessed to be back at this wonderful club,” Lukaku said on the club’s website. “It has been a long journey for me: I came here as a child who had a lot to learn, now I come back with a lot of experience and more mature.
“The relationship I have with this club means so much to me, as you know. I supported Chelsea as a kid and now to be back and trying to help them win more titles is an amazing feeling.
“The way the club are playing is perfectly in line with my ambitions at 28 and just won Serie A. I think this opportunity comes at the right time and I hope we can have a lot of success together.
“Since leaving Chelsea it’s been a long journey with a lot of ups and downs, but these experiences have made me strong and the challenge is to try and help the team win more trophies . I can’t wait to get started and help the club be more successful. “
After leaving Chelsea in 2014, Lukaku became one of Europe’s most prolific strikers, scoring 87 goals in 166 games for Everton between 2014 and 2017, and 42 goals in 96 appearances during his two years at Manchester United. before signing for Inter in 2019.

“We are of course looking to build on the success of last season, and Lukaku will play a big role in achieving our goals. “
Chelsea, who were also interested in signing Erling Haaland from Borussia Dortmund, were in the market to sign a striker following the sale of Olivier Giroud to AC Milan.
Lukaku asked Inter to agree to Chelsea move, although he said publicly that he would be stay in Milan before Euro 2020.
Inter initially viewed Lukaku as untouchable this summer, but changed their stance in the face of pressure to reduce their payroll.
The lack of funds available at the Italian club prompted Antonio Conte to leave Inter in May. He was replaced by Simone Inzaghi.
“A fantastic movement at all levels”
Belgium boss Roberto Martinez called the move “fantastic” for Lukaku.
After making his senior international debut at 16 in 2010, Lukaku scored 64 goals in 98 appearances for Belgium, helping them to finish third at the 2018 World Cup.
“It’s a fantastic move across the board,” Martinez said. “Romelu knows the Premier League like the back of his hand.
“He had two incredible seasons. Few people in British football have had the level of impact he has had in a very important project. Inter Milan were a team built to try to win Serie A. It’s not easy, with Juventus winning nine straight titles, you can see the task.
“Romelu Lukaku has become this central actor on which a new project is built. Very consistent, he has become a leader in the field, and I think that level of maturity is very evident in his game.
“Chelsea take Romelu Lukaku, a player they know well because he signed for this club 10 years ago, but he’s a very, very different player now. Probably at the best time of his career. “
