Hazard’s Chelsea future remains in doubt as he nears the final 18 months of his current deal.
Chelsea are desperate to renew the Belgium international’s contract but talks have not resulted in an agreement.
Real Madrid are interested in signing Hazard as they look for a successor to Cristiano Ronaldo, while Paris Saint-Germain are sniffing around.
Hazard has made no secret of his childhood desire to play for Real.
But the 27-year-old is torn between those dreams and remaining at Stamford Bridge.
Speaking in an interview on French TV show Canal Football Club, Hazard was asked about his transfer situation.
And while Hazard was coy about the possibility of a move, he did make a promise to Chelsea fans.
“I have one year left in June,” Hazard said.
“If I don’t extend, (a move) is possible.
“I can’t see myself leaving in January. I wouldn’t do that to the club, the fans.
“Next summer it’s a possibility, but it’s also possible that I spend the rest of my career at Chelsea.”
Hazard was also asked whether he had spoken to suitors about a Chelsea exit.
And he sensationally confirmed talks with PSG had taken place.
“I had contacts with PSG, but it did not tempt me,” Hazard said.
“I have always said that if I came back to Ligue 1 it would be to Lille.”
Chelsea tied N’Golo Kante to new long-term deal on Friday and manager Maurizio Sarri spoke of his hope that Hazard will also sign a renewal.
“This (Kante) is very important news, he is a very important player for us,” Sarri said.
“He is very important player for us in the defensive phase and is improving in offensive movements.
“Now he has to improve in the last 20-25 metres, he can score more.
“I don’t know about a new contract (for Eden). I don’t know about the evolution of a new contract, I think we can do it. I hope so.”
