"Alvaro has to gain confidence with one, two, three goals", Sarri added.
Chelsea were more comfortable than the 1-0 scoreline might suggest.
Speaking at his pre-match news conference, Sarri said of Hazard: "He told me after the national team, and the match against Cardiff, he was a little bit exhausted, so I thought it would be better for him to stay at Cobham and rest".
They took the lead with just seven minutes gone after Ross Barkley dribbled through the PAOK midfield and teed up Willian, who slotted home from close range to score his 20th goal in UEFA competitions. In this match he has had three or four opportunities.
The Belgian playmaker has been in superb form for the west London club so far this season and he has scored five goals and made two assists in five Premier League outings so far.
"I am happy with the result but we had a lot of opportunities and didn't kill the match".
"My mind was always to play for Chelsea and now with Maurizio Sarri we have a different way to play football, so I just want to enjoy and continue to play for this club".
'I hope for him in the future I can help him.
Pedro was forced off with a shoulder injury after colliding with Paschalakis, and Chelsea held on to secure their first three points of the group stage. He was on the ball and was active'.
He is yet to feature under Sarri and did not travel to Greece with Chelsea's 21-man squad for their Europa League tie. "Good win today boys, Come on Chelsea!".
