The 27-year-old has been earning plenty of praise for his solid performances for the west London club this season as he and his team-mates get used to life under new manager Maurizio Sarri.
Hazard has struck five goals and made two assists in five Premier League games so far this season to help the Blues top the table and keep a 100 per cent start to the new campaign.
The Belgian playmaker has been in superb form and he will be hoping to continue his fine displays as he bids to try and help Chelsea FC to challenge for the title this season.
However, Chelsea FC assistant manager Zola seems to think that Hazard still has plenty of room for improvement at Stamford Bridge as the season unfolds.
Speaking in an interview with Chelsea TV, Zola said of Hazard: “I think he’s still not at his best. The more he plays in and understands the system, he’s going to be even more effective.”
Hazard will be expecting to start for Chelsea FC when the Blues return to Premier League action on Sunday afternoon with a trip to West Ham United.
The Blues are aiming to at least break back into the top four this season as they bid to try and bounce back from their fifth-placed finish last term.
