The Hornets are just 90 minutes away from securing a return to the Barclays Premier League when they tackle Crystal Palace in Monday's npower Championship play-off final at Wembley - and with it a bumper £120million windfall which would change the financial landscape of the Hertfordshire side.
It could certainly be argued the 46-year-old Italian, who enjoyed a glittering playing career at Napoli and Chelsea, has unfinished business with the English top flight following his dismissal from a first senior managerial role at West Ham in May 2010, where he had been in charge for only two seasons.
Zola, though, is determined to look forwards and savour the opportunity presented by businessman Giampaolo Pozzo, who headhunted the Italian coach following the completion of his family's takeover at Vicarage Road last summer.
"Coming to Watford was exactly what I needed," Zola said. "It gave me the opportunity to work on certain ideas that I had, which in the first year (at West Ham) was maybe a bit more difficult when the results were very much needed.
"With West Ham we were many times in a position where we were under pressure and when you are under pressure the first thing you look for is the result, but that is not necessarily the good way to build up things.
"There were a few mistakes as well and if I had to do the same things now I would do them differently. But in those circumstances you tend to work for the results and then you forget the results are a consequence of the way you work.
"If you look for the performance all the time and build up the performance, improve it day by day, week by week then the results will be like a guarantee, or nearly, and that is what I believe we have done really well at Watford this year.
"We started very slowly, but then every week we added something to the team and got to a point where we went quite a while unbeaten and had a few good spells.
Zola added: "I have said many times I do not know what is around the corner for me but I want to do something important for the club. If I cannot make it this season, then I will try again next year."
