The Belgium international suffered a back problem during Chelsea FC’s 2-2 draw with bitter rivals Manchester United at Stamford Bridge last month.
The 27-year-old was forced to sit out Chelsea FC’s 3-1 victory over BATE Borisov in their Europa League clash in west London as Ruben Loftus-Cheek netted his first hat-trick for the club.
Ross Barkley seized his chance to shine in Hazard’s absence and scored a goal as well as making two assists in a 4-0 win against Burnley at Turf Moor last weekend.
Hazard has made a brilliant start to the Premier League season following a return of seven goals in nine games in the English top flight.
Former Chelsea FC forward Zola, who is currently working as Maurizio Sarri’s assistant manager at Stamford Bridge, is confident Hazard is nearing a return to first-team action.
“He is certainly much better,” Zola told his pre-match media conference on Tuesday ahead of their League Cup clash against Derby County.
“He is looking quite good for the weekend [the home game with Crystal Palace on Sunday].
“We are pleased because he is such an important player for us.”
Chelsea FC cemented their position in third place in the Premier League table and are two points adrift of leaders Manchester City and Liverpool FC.
The west London side remain unbeaten in the English top flight following seven victories and three stalemates to collect 24 points from their opening 10 outings.
Hazard is looking to win the Premier League title for the third time in his Chelsea FC career, having previously got his hands on the top-flight crown in 2015 and 2017.
The Belgian forward has also won two League Cups, the FA Cup and the Europa League during his six-season stint at Stamford Bridge following a move from Lille in 2012.
Hazard has been regularly linked with a move to La Liga giants Real Madrid over the past few seasons and the speculation has only intensified in recent months.
