Maurizio Sarri suggested Eden Hazard has a similar impact on Chelsea as Lionel Messi and Cristiano Ronaldo do at their respective clubs after his side beat Watford on Wednesday.
Hazard scored both goals, his 100th and 101st for the club, as the Blues claimed a 2-1 victory at Vicarage Road to put themselves two points ahead of fifth-placed Arsenal.
The Belgium star has been directly involved in 19 Premier League goals this season, the most of any player in the competition, and Sarri had only the highest praise for the forward's quality.
"He is very important for us. Messi is very important for Barcelona, Cristiano Ronaldo is very important for Juventus." Sarri said.
"He is a very great player. He is able to play in every position. At the moment he is playing as a false number nine and he is very able to play in that position.
"Today he scored two goals and I think he made two or three very good [chances].
"He is very able to come play with team-mates and to open space for his team-mates."
Sarri was thrilled with his side's display, even though he felt they perhaps played better football in their 1-0 loss to Leicester City at the weekend.
"Maybe we played with quality against Leicester, but today we had much better application for the 90 minutes," he said.

There were some eyebrows raised when youngster Callum Hudson-Odoi, on in the first half for the injured Pedro, was himself replaced by Emerson Palmieri with five minutes of normal time left.
However, Sarri explained that the decision was a precaution based on an injury concern for the winger.
"He played very well for 55 minutes," said Sarri. "He had a hamstring problem a week ago and [with] 10 minutes to go he had some pain, so we decided to change.
"I can understand [the confusion], but there wasn't another solution. It was too dangerous."
Watford boss Javi Gracia felt his side could have taken a share of the spoils had they been more clinical with some opportunities.
"Players like Willian, [N'Golo] Kante, Hazard, Pedro can do something different," he said. "We tried to be constant and different and defend well. If you take the chances you have, then maybe you take the points."
He added of Hazard: "It is difficult to stop him. It is different if you stop him as a number nine or on the left. He is a player with special quality, speed and skill."
