Graeme Yorke of the Daily Mail reports that the Belgian player has admitted that he may be swayed into a move to Paris Saint-Germain if his wife desires a move back to France.
In an interview with Canal Plus, Yorke writes that Hazard said: "If my wife was to say: 'Honey, I'd like you to go to PSG', I would have to take it into account."
This admission will give Blues' fans palpitations and could give Jose Mourinho a huge problem going into the next campaign as he looks to strengthen the Stamford Bridge club's squad.
Belgian press reporter Kristof Terreur also confirmed Hazard's comments from his original interview.
Strangely, Hazard was also happy to conduct his post-Champions League match interview on Wednesday night wearing a swapped PSG jersey.
The player has been the driving force behind Chelsea's title chase, as Mourinho's forwards have failed to hit the target on countless occasions.
Hazard is the club's top scorer this season from his deep attacking role, scoring 14 times in 32 Premier League games, per Squawka.
The reason that Mourinho was happy to lose Juan Mata to Manchester United was because he had the brilliance of Hazard. If he now loses the player to PSG, he might have to rip up the textbook and completely start afresh.
In the short term, the loss would be devastating to Chelsea and the Special One, and the outlay on rebuilding if Hazard departed would be immense.
Oscar and Willian have both shown that they have talent and can grow further in the West London team, but they do not possess the X-factor that Hazard does.
Hazard is on the same path as Lionel Messi and Cristiano Ronaldo were once on as younger players, and he might feel that PSG will offer him a bigger stage in the longer term than Chelsea will.
Their power and wealth is clear, and with an array of talent already at a great depth, Hazard would be the cherry on the cake for the Parisians.
