Chelsea boss Jose Mourinho is yet to make a definite decision over the sale of Romelu Lukaku.
Mourinho has doubts over the 20-year-old's ability to perform at the highest level and may be prepared to let him go to raise transfer funds.
The London Evening Standard says Chelsea plan to wait until after the World Cup to decide whether they will sell.
Lukaku has scored 12 goals for Everton this season and is expected to start up front for Belgium at the World Cup. A strong showing in Brazil will obviously increase his value.
