The former Napoli boss has given the Belgian freedom to express himself at Chelsea and the free-flowing style of play at Stamford Bridge is bringing the best out of their star player. "In these actions I think he spends a lot of energy, and he can have more energy in the last 25 metres".
Despite his pace, flair and artistry on the ball, the Belgium worldwide just doesn't score enough.
Hazard took his tally to five in five on Saturday as he scored a hat-trick in Chelsea's 4-1 win over Cardiff.
Should Chelsea mount an unexpected title challenge, it will be down to their resilience in holding onto Hazard.
According to Carragher, not only was Hazard the best player at the World Cup in Russian Federation, but he is also the best player in the English top flight.
Hazard has now scored 5 goals and assisted 2 in 5 Premier League appearances so far.More news: Teddy?: 'Atlanta' FX Character Teddy Perkins Crashing The Emmys Had Twitter Shook

The Blues won their first four games of the new season but Sarri is well aware that teams can suffer a downturn in results after such a break.
"If he wants to play for another season I think it's right he tries to play", said Sarri. "They have different characteristics, and it depends on the kind of match".
Now, Chelsea are apparently ready to abandon their strict policy over contract extensions for players above 30 years of age by offering Luiz a two-year deal that could see him earn £125,000-a-week.
"I'm not sure Chelsea will dominate the league enough to create enough chances for Hazard to get 40 goals, because of Liverpool and Manchester City", Pearce explained. "If you saw the game today, you have to say (he believed me)". Even without their win over Everton, I would have been slightly concerned about this fixture.
However, Hazard remained a Chelsea player and has started the season in phenomenal form.
"Mentally the match after the (international) break it is very hard; materially because we will play against a very physical team", he said. "We all have to help him to score goals and help him to continue like this".
