Real Madrid are reportedly considering the possibility of offering Mateo Kovacic and Isco in exchange for Chelsea winger Eden Hazard.
The European champions have been frequently linked with an approach for Hazard, who has just over 18 months remaining on his contract at Stamford Bridge.
Speculation will continue until Hazard makes a final decision on his future, but according to Onda Cero, Real are looking to tempt Chelsea into a sale.
The report suggests that the La Liga side are willing to allow Kovacic - who is already on loan at Chelsea - and out-of-favour Isco to make the switch to West London.
Real are likely to value the pair at a combined total of over £100m, and Hazard's price-tag will become lower as long as the playmaker does not pen a new contract.
