"This is a process. You cannot think after a month that everything is going to work in the right way," the 44-year-old said, per Chelsea's website.
"I really appreciated Carlo’s words. I worked under Carlo and his career is something unbelievable. He knows better than me and better than many, many people in this business, the way to reach something important.
"I worked with Carlo when he was near enough my age in this moment and he was sacked by Juventus but at the end, it is not something magic that you can reach in two days. That is something different. That is PlayStation, not football."
Maresca added: "Day-by-day, you need to work and you need time and I know most head coaches ask for time and it sounds like an excuse but it is not an excuse, it is the reality."
