The Belgian has emerged as one of the Blues’ top targets over the course of the past few weeks, with the highly-rated star having wowed since he left the London club on a permanent transfer in 2014.
Everton are, naturally, keen to keep hold of their talismanic forward and are set to discuss a new contract with his agent, Mino Raiola, this week, but Chelsea remain interested.
And reports claim that they are willing to wait until the very end of the transfer window to get the 23-year-old, with a £65m offer being prepared.
Such a fee will make Lukaku the most expensive player in the club’s history, surpassing the £50m they paid Liverpool for Fernando Torres in 2011.
The burly forward is the player Antonio Conte wants to spearhead his attack after a much talked about move for Alvaro Morata failed to come to fruition.
The Express’ claims somewhat contradict reports from the Daily Star that the club have turned their attention to Mauro Icardi after growing frustrated by Everton’s hardline stance.
