Hazard has been a long time transfer target of Real Madrid and even with his contract with Chelsea running down at the end of the 2019/20 season, it was rumoured that the Spanish club would have to part with upwards of £100 million to prise him away from England.
Higuain toiled on loan at AC Milan in the first half of the season, but the Argentina worldwide previously hit 36 Serie A goals in a season for Sarri's Napoli.
And the 60-year-old Blues boss says the 31-year-old striker is keen to respond from a disappointing loan spell at AC Milan earlier this season.
Great news for Chelsea fans, but Fabregas also dropped the bombshell that Hazard has always said he likes Real.
The goalscoring burden at Chelsea now falls heavily on new arrival Gonzalo Higuain and Hazard senses a fruitful relationship with the Argentina striker. "In my first season in Naples, he arrived later [due to the Copa America]. It's a football feeling, I think".
"My team-mates and my colleagues have been incredible but Eden is the best player I've ever worked with". None better than Eden Hazard, though.
Next up for Hazard, Higuain and Co is a trip to Manchester City on Sunday.
I will be really very happy with him if he will want to stay, because in my opinion he's the best in Europe.
He told Radio Marca on Thursday: "If Hazard has said that he already made his decision, then I think it's because he'll renew his contract with Chelsea". Though Chelsea succeeded before Hazard, and will go on to win plenty in the years post his departure, he's one of the top five players on the planet, and it's been a pleasure to see him in action in SW6 over the past six-and-a-half-years.
Barcelona's Lionel Messi and Cristiano Ronaldo of Juventus clearly have more pedigree than Hazard, but Sarri may have been talking about the Belgian in the context of his position on the left wing.
