Maurizio Sarri said Eden Hazard can score as many as 40 goals this season if he focuses fully on the final third of the pitch after his hat trick propelled Chelsea to a 4-1 victory over Cardiff City on Saturday.
More history could have be made on Saturday as Watford also began the season perfectly, with four wins in four.
Liverpool and Chelsea continued their ideal starts to the Premier League season on Saturday, and together have done something England have not seen in over a century.
The Belgium star needed just six first-half minutes to erase an early deficit and later returned to seal his treble from the spot as the hosts continued their flawless start to the new season.
"Now we have to prove that and do it again and again". The Spaniard is Chelsea's vice-captain, in Cahill's absence, he steps into the role.
Roberto Firmino tapped home a second nine minutes into the second-half and Liverpool should have added to their lead as Sadio Mane and Naby Keita were denied by Vorm.More news: Trump authorizes sanctions against foreigners who meddle in United States elections

"Chelsea is his home, of course".
Hazard sent Cardiff goalkeeper Neil Etheridge, who had already saved two penalties this season, the wrong way to complete the second Premier League hat trick of his Chelsea career.
Sarri has enjoyed a fast start in his initial campaign in England as the Blues recorded four wins on-the-trot in as many Premier League games.
However, Hazard scored twice in seven minutes before half-time to send Chelsea in on top.
It remains to be seen how they'll cope with a top Premier League side, discounting Arsenal who are still finding their rhythm under new boss Unai Emery.
And Wilfried Zaha underlined his importance to Crystal Palace with the only goal in his return from injury in a 1-0 win at Huddersfield.
