The Blues are on the hunt for a new striker at the end of the season and face fierce competition for their top target, Borussia Dortmund (opens in new tab) youngster Erling Haaland.
According to the Sun (opens in new tab), the London club are pessimistic about their chances of signing the Norwegian will turn instead to a familiar face.
Lukaku fits the profile of striker they are looking for, possessing the mental strength required to spearhead their attack next season.
The 27-year-old is on the brink of firing Inter to their first Serie A title since 2010, and has scored 27 goals in 40 games in all competitions this season.
Tammy Abraham has failed to persuade manager Thomas Tuchel of his ability, while Timo Werner continues to struggle in England following his £48m arrival from RB Leipzig last summer.
Lukaku was on Chelsea’s books for three years between 2011 and 2014, spending two seasons out on loan at West Brom and Everton (opens in new tab)before sealing a permanent move to the Toffees.
The Belgian later spent two seasons at Manchester United (opens in new tab) from 2017 to 2019 before sealing a £73m move to Inter, where he has been a huge success.
Lukaku has scored 61 goals in 91 games for the Italian giants altogether, leading them to the Europa League final in his first season before this term’s title charge.
But Chelsea could have to fork out more than £90m to secure his signature this summer.

Our mission is to offer our intelligent, international audience access to the game’s biggest names, insightful analysis... and a bit of a giggle. We unashamedly love this game and we hope that our coverage reflects that.
