Chelsea have reportedly put a world-record fee in excess of £200 million, if they are to sell Eden Hazard this summer, according to a report.
Real Madrid remains the favoured destination for Hazard, but Chelsea will not sell their star man cheaply.
Dailymail reports that the London club know the price tag will scare suitors away at this stage of the window.
But Hazard is not pushing for a move to Madrid and the club's new coach, Maurizio Sarri, has said he is ready to work with the Belgian and Willian, who missed out on a move to Barcelona.
However, there is growing concern that the former Lille man may not extend his contract at Stamford Bridge. He has two years remaining on his current deal and has not agreed to the club's new deal worth £300,000-a-week.
Chelsea will also have to solve their goalkeeping situation, when Real Madrid target, Thibaut Courtois returns from holiday.
Courtois has just one year left on his contract and talks over a new deal has not progressed since May. The 2018 World Cup golden glove winner has expressed desire to reunite with his family in Spain.
Chelsea have also continued talks with Juventus for defenders, Daniele Rugani and Matteo Caldara.
The London club also remain confident of signing Gonzalo Higuain, but might face competition from AC Milan, who are also interested in the Argentine, as well as Chelsea's pair of Alvaro Morata and Tiemoue Bakayoko.
According to the report, Morata is likely to leave should Higuain arrive, which would allow for a three-way deal, whereby Milan would withdrawal interest in the Juventus striker in order to get Morata.
