Their fifth-place finish position left Chelsea without a spot in the European elite competition, with the lack of continental tournaments likely to deter many star players from staying put at Stamford Bridge.
Particularly, Courtois, who has still not renewed with Chelsea and could be available from January. According to 'Onda Cero', the goalkeeper is unwilling to extend his contract in hope of a move to Real Madrid.
'AS' also confirms that Belgian is very keen on a move to the Spanish capital, not just for footballing reasons but because his two children live in Madrid.
Zidane's side have long been linked with the search for a new goalkeeper, especially with the imminent departure of Kiko Casilla. Courtois, who has a market value of roughly €60million, is looking like an increasingly viable option.
On the other hand, it is no secret that Hazard has caught Zidane's attention. His contract with Chelsea is due to expire in 2020, but their disappointing campaign this season could change everything.
Although Neymar is widely tipped to be joining the Bernabeu, Hazard's price would be significantly lower than the Brazilian star who is unlikely to leave Paris Saint-Germain for less than €300million.
