The playmaker spent months on the sidelines over the summer after suffering an ankle injury, which required surgery.
Hazard has since returned to the pitch, making seven appearances in all competitions for the Blues, but he has started just one Premier League game - a 1-0 defeat to Manchester City.
The 26-year-old impressed for his country on Tuesday night by scoring twice in Belgium's 4-0 rout over Cyprus, but the midfielder has warned fans not to expect too much from him.
"I don't know, I will see at the end of the season," Hazard told reporters. "I missed football for three months [and] it's not easy to come back after a big injury but I did.
"I worked out during the summer. I just want to play football. I will miss some games, I will play bad for some games. I just want to play football and try to bring the best of me."
Hazard has been named among a 30-man shortlist for the Ballon d'Or.
