The Italian spent seven memorable years at Stamford Bridge during his playing days, with his number 25 jersey having been retired by the club as a mark of respect.
He would like nothing more than to make an emotional return to west London in a coaching capacity, but appreciates that he is not yet ready to take such a giant leap.
Having cut his managerial teeth at West Ham, Zola is currently overseeing events at Championship outfit Watford.
Working with ambitious owners at a club aiming at the Premier League can only be beneficial to him, though, and the 46-year-old hopes that one day he will be offered an opportunity to enhance his legend status at Chelsea.
"I have been dreaming of becoming a good manager, one who can lead a team like Chelsea," Zola told France Football.
"I work really hard for it. I do not know if I will (manage Chelsea). I think I have the abilities but I do not think I am good enough yet.
"It is only my second coaching experience in a club after West Ham. I still have a lot to do.
"I am really pleased by the plans (at Watford). I know how serious the Pozzo family are. This is the best place I could have found to develop as a coach."
