The Blues forward is being courted by Real Madrid and is expected to be the subject of a huge offer in the summer as Zinedine Zidane looks to strengthen his side.
Hazard refused to rule out the prospect of leaving Stamford Bridge, although claimed he was happy in south west London.
“At this moment, there’s nothing [a contract] on the table. We’re waiting for the end of the season,” the 26-year-old told Het Nieuwsblad.
“I’m still calm. We will talk. If not, then we’ll see.”
When asked if there is a chance he might move to a European rival in the summer, the Belgian replied: “For the moment, I don’t know. I’m happy at the club.
“When I’m back from the national team, we’ll have time to talk and see what’s possible.”
Antonio Conte has been linked with a number of potential stars from across Europe including Tottenham’s Kyle Walker and Real Madrid’s Alvaro Morata.
Lukaku is also on Chelsea’s radar after the Belgian announced that he wanted to leave Everton to play in the Champions League.
He has unfinished business at the Bridge, given that he was let go back in 2014, and it seems Lukaku would be keen on a return.
However, the Toffees have slapped a world record £100million price tag on the head of their star man, which could provide a stumbling block for even the wealthiest teams.
And it seems Hazard is well aware of this fact. While discussing a potential extension at Chelsea, he joked: “If I sign a contract, maybe there won’t be enough money left to get Romelu!”
“I’m kidding. Whoever comes in, we’ll be ready for the new season.”
