The 21-year-old, who is the brother of Blues winger Eden, has impressed during loan spells with Belgian outfit Zulte Waregem over the last two seasons.
Hazard has said that he is keen to impress outside of his homeland if he fails to make it into Jose Mourinho's Chelsea squad next season.
"At the end of the season, I'm going back to Chelsea and we will discuss my future," he told RTBF.
"I have a preference for the Premier League or the Bundesliga – I do not think I will stay in Belgium."
Hazard moved to Chelsea from Lens in 2012.
