The Chelsea legend has had a torrid time as manager, having been sacked three times in his five managerial jobs.
Zola also resigned from his position as manager at Watford and Birmingham.
The Blues legend is now focused on furthering his coaching education rather than getting a new job as manager.
Speaking to reporters Cobham Training Centre.
“I was surprised when this opportunity came to me, I was very surprised.”
“Considering my previous job with Birmingham, it was very painful for me. I could not believe it. This is a blessing for me.
“This is the best reason and why I am throwing everything I have got to make the best of this experience for Maurizio and the club.
“I haven’t honestly thought too much about it [getting back into management]. Right now, I am very happy to be the number two of Maurizio and in this club.”
“I think It is an amazing experience for learning. If you go back to the start of my story, I started like crazy to go in my first experience in the Premier League with West Ham. It went well but I think I missed a lot of things in my experience in management, but I am catching up with this experience.
“I think I have seen very few coaches that when they work, they are so detailed and work so much like Maurizio does on the games and with everything he does.
“What you see on the pitch is the result of the huge work he does behind the scenes.
“It is a lot of work honestly, everyone, not only him, but everyone in his coaching staff works a lot.
“We don’t want to leave anything to coincidence so for me it has been quite an experience. The more you work, the more you find the energy to work and this is the most important thing.
