Hazard was linked with a move away from west London for a number of years before eventually joining Real Madrid for a fee of €100million (£85.9million) in the summer.
The Belgian playmaker joined Chelsea from Lille in 2012, but has said he is enjoying training a lot more at Real Madrid under Zinedine Zidane – who was one of the main reasons for him joining the Spanish side.
“The training is always with the ball,” Hazard told L’Equipe.
“When you have experimented with Italians, as I have done with Conte or Sarri, you have much less fun. Everything is framed.
“It’s hard to compare. I was attracted to Zidane at Madrid and felt very identified. He fascinates me and even has some power over me.
“During Euro 2016 he told me: ‘It would be good if you came’. And when Zidane calls you it’s hard to say no.
“He loves his players and you feel that the dressing room is happy to have him as a coach.”
Hazard admitted that playing for Madrid was his childhood ambition.
“It was a dream to get here. Ever since I started playing in my garden as a kid, they were the club I supported. Zidane was my idol. When I watched him on television he was magic.
“The stadium, when I saw it on television, was magical. And the white jersey, impeccable. For me it was exceptional.”
