Hazard, one of Europe's most sought-after rising stars, has been heavily linked with a host of big-name clubs including Premier League rivals Manchester City, Manchester United and Chelsea.
However, after scoring a hat-trick in what was almost certainly his final game for Lille last night, the 21-year-old Belgium international said he had not made a decision on his future yet.
"I have not made my choice yet. I haven't signed anything," said Hazard, who also suggested Chelsea's triumph in Munich on Saturday had provided him with further food for thought.
When asked about a possible move to the Blues, he was quoted as saying by France Football: "Now, yes. They won the Champions League so they will be back in that competition next season.
"It's important for me to play in that competition. Chelsea are a great team with great players. Of course it's a possibility."
