The Belgian striker is being targeted by new Chelsea boss Antonio Conte
Decision time for Romelu Lukaku
The Italian journalist is reporting that the Blues have made a bid of €60 million (£50 million) for the Belgian striker, a move that would pave the way for Diego Costa to force an exit to Atletico Madrid.
Both moves would see the forwards moving back to former haunts, with Lukaku famously leaving Chelsea for Goodison Park back in 2014 for a Toffees record fee of £28 million, whilst Costa joined Chelsea that same year for £32 million.
Lukaku joined Chelsea as a teenager from Anderlecht
Should Chelsea decide to re-sign the man they let go of in 2014, the Blues stand to fork out £40 million more than what they originally paid to sign him from Anderlecht as a teenager.
Lukaku originally left the Blues to prove himself after a difficult time in West London, deprived of first team opportunities and sidelined under Andre Villas-Boas and then unwanted by Jose Mourinho.
After a successful stint at West Brom on loan, where he scored 17 Premier League goals during the 2012-2013 campaign, he chose to join Everton on another loan deal under the stewardship of Roberto Martinez. After becoming a key figure in the Spaniard's side, he joined permanently.
Romelu Lukaku is Belgium's leading man
The now 23 year old has well and truly established himself as a top Premier League forward since departing the Bridge, with 60 Premier League goals already to his name.
And after a disappointing season last term, Lukaku has set his sights on a move to a bigger club, with new Toffees manager Ronald Koeman appearing to have failed to persuade the Belgian international to stay.
Lukaku has played for Everton since 2013
This comes in contrast to reports as recently as yesterday, with the Liverpool Echo claiming Everton were confident of keeping hold of their star man.
It seems Antonio Conte is looking to link up Lukaku with his compatriot Michy Batshuayi at the Bridge, who signed earlier this month from Marseille.
The question now is, will Lukaku want to return to Stamford Bridge, despite all that has gone before? That is challenge for new Blues boss Antonio Conte.
