Chelsea are looking to bring back the man who left Stamford Bridge for Everton just two years ago, but Everton are not keen on selling the Belgian.
Chelsea were rumoured to have bid around £60m, but Everton are hoping for at least £75m for their number one striker.
However, according to the 'Express', the Toffee's would prefer Lukaku to stay at the club, rather than cash in on the forward. This means that Koeman's side will attempt to discuss a new deal for the 23-year-old and hope that he won't be tempted to re-join his former club.
