The former Chelsea man is looking forward to the Championship play-off final and feels victory over Crystal Palace at Wembley could top all his achievements as a player
The former Italy international enjoyed great success as a player, winning the league title in Italy with Napoli as well as the Uefa Cup with Parma and two FA Cups with Chelsea.
However, the 46-year-old feels that victory on Monday would mean more to him than the trophies he won as a player.
"Winning this game will be one of the most important [of my] achievements,” he told reporters.
"As a manager, everything is multiplied, so if it happens, then it is going to be amazing and I am sure I will celebrate the same way I celebrated when we won the first FA Cup with Chelsea at Wembley."
Watford finished the season in third place before beating Leicester in thrilling fashion in the play-off semi-finals, a victory Zola admits will live long in the memory.
"As a footballer, you feel you played at different venues in important games, and you think that you lived all the experiences in football, the good and bad ones, but as a manager it amplifies everything - that is what happened to me against Leicester, I went back 20 years. Fortunately for me it was a good feeling, and that was great," he added.
"I have been blessed to have enjoyed a fantastic career, with some very good moments, but to win this one would have it rated as one of the best because of everything you go through as a manager.
“You take in every player's emotion, positive and not positive so you live everything.”
