Lucio, 34, has penned a two-year deal with Juve.
"I'm happy, it's a new experience, a new chapter in my life and I'm now looking forward," Lucio told Juventus Channel.
"The past will stay with me, but I'm aiming to enjoy success again.
"I think the most important thing is today and tomorrow. Yesterday is already history and I believe that the motivation needs to be right.
"You have to train every and play with the right mentality, which is to do your best to win.
"Juventus have always been a strong side, I also said that when I came to Italy for the first time, Juve will always be Juve.
"It's clear their motivation is greater with the new stadium. The support is incredibly strong and certainly pushes the team to go forward with greater enthusiasm. It's definitely an added weapon to Juve's armoury."
