The Belgian forward joined Chelsea in a £32 million deal from Lille in 2012 and the 26-year-old revealed that he would be open to returning to the French side one day.
Paris Saint-Germain are among a host of potential suitors ready to swoop in for the Belgian, with right-back and Belgian compatriot Thomas Meunier urging the attacker to join him in Paris.
A Real Madrid target in recent times, Hazard has never stated his intentions of leaving Chelsea, but he did say he would be open to rejoining Lille.
'There are some big clubs [in the Ligue 1], and it was an attractive league even when I played in it six years ago', Hazard told French outlet SFR Sport.
'Big stars want to play in Ligue 1, and that is a good thing. But if I am to return it will be to play for Lille, they are my club', the winger added. 'I still have a career to carve out, with a number of seasons ahead of me'.
'I am at Chelsea for the time being, and I don’t know where my career will take me in the future, but if I do go back to France it will be to play for Lille', Hazard concluded.
