Hasselbaink scored twice against Everton in the Blues' 4-1 Worthington Cup fourth round triumph in midweek and is again poised to lead the attack in the Premiership rematch between the two sides tomorrow.
Despite a slow start, Chelsea's leading scorer from the past two seasons is now coming back into prime form as he rediscovers full fitness after a summer operation. 
Hasselbaink insisted: "I'm not really bothered about my goals, I just need to get my fitness and to work hard.
"As there were no new players in the summer, they didn't have to settle in. We said to ourselves that we had to do it for ourselves and do it together, and now it's really working well."
Zola told Sky Sports: "I'm pleased for Jimbo as he's such an important player for the club and, despite what he says about not being bothered by his goalscoring, nobody believes him.
"He's a goalscorer and he needs that so I'm very happy to help him as his goals will help the team to progress. We're going through a really good spell and there is a really good atmosphere in the squad, as well as the quality."
