Hazard, now in his seventh season at Stamford Bridge, is enjoying new head coach Sarri's style.
"I like to have the ball. Not in my own half, but in the last 30 metres," Hazard told Chelsea TV.
"I like this type of game. It's completely different than Antonio Conte or (Jose) Mourinho before. We have more ball so for me it's not bad."
After victory over Bournemouth, asked how he is, Hazard said: "Good. You can see on the pitch. Let's see the future."
