With the Bernabeu club failing to secure the signing of David de Gea over the summer, they are keen to add a new galactico to their ranks in the near future.
However, the Stamford Bridge club will be able to draw inspiration from the Red Devils' successful fight to keep hold of their number one.
Los Blancos have a history of signing top talent from England, with Cristiano Ronaldo and Gareth Bale moving for world record deals in the past.
The publication believes Perez would not be put off by the huge fee that would be commanded for his signature.
There is also the possibility of Ronaldo being sold - amid suggestions he will not see out the remainder of his contract in the Spanish capital -to help fund a deal for what would potentially be his replacement.
Alternatively Bale could be ushered out after three years at the club, but Perez is a huge admirer of the Welsh superstar so that would appear to be highly unlikely.
No deal for Chelsea's number ten would take place until next summer at the earliest. However, when Madrid come calling they very often get what they want - so it may be time to start enjoying Hazard while you can Blues fans.
Will Eden Hazard move to Real Madrid in the future? Have your say in the comments section below!
