Hazard is now at the World Cup with the Red Devils, where he will contest the third-place playoff against England on Saturday.
He said last week: "The point is: my children live in Madrid".
It's rumoured that the Belgian, who has been one of the stars of the World Cup, would be part of a plan to acquire several world-class players to fill the void left by the Portuguese legend for Los Blancos.
In fact, several big names like Kylian Mbappe, Harry Kane, Eden Hazard and Neymar have been linked with moves to the Santiago Bernabeu in recent weeks. "Zidane or no Zidane, the white jersey [of Madrid] is special but the blue jersey [of Chelsea] suits me well so it does not bother me if I stay".More news: US hits China with $34B round of tariffs; Beijing strikes back

It has been floated that even Barcelona are interested in signing the winger, but it has been claimed that Catalan giants are not likely to make a move.
Eden Hazard has cast serious doubts over his future at Chelsea after suggesting that, in the wake of an impressive World Cup campaign, the time may have come for him to move on after six successful years at Stamford Bridge.
"It's a very easy question for me, he is one of the most complete footballers in the modern game now", Martinez told reporters of Hazard.
Hazard is yet to commit to a new deal at Chelsea, and with his current deal expiring in 2020, Barca apparently feel they have a chance of luring him to Spain.
It remains to be seen whether Hazard will be keen to stay and work under new manager Maurizio Sarri following the sacking of Antonio Conte on Friday.
