The Belgian international was recently dropped for missing a Eurostar back from France, which caused him to turn up late for training.
Hazard feels that although he is enjoying life with the Blues, he could be doing more during games.
"I feel very well," Hazard is quoted as telling The Mirror.
"The coach (Jose Mourinho) gives me time to play and I have made goals. But I know I can do better."
The Blues are currently fourth in the Premier League.
