The former Brazil boss has applauded the Old Lady for securing the services of the veteran defender, whom he feels is a born winner and will boost the side's chances of success.
The 34-year-old spent three years at Inter, having been signed by Jose Mourinho, and won a Serie A title, a Coppa Italia and the Champions League in his maiden season, but was released earlier in the summer as the side finished a disappointing sixth place.
However, that did not deter arch-rival Juventus from swooping for the experienced Brazil stopper, and his former Selecao coach believes it is an inspired signing by the Scudetto holder.
"If I had to go to war, Lucio is the first player I'd take with me," Dunga told Tuttosport. "He's a great signing, trust me. Lucio is a champion and a true leader. He fits in with Juve's hunger for success because he always wants to win. With this, he will drag the rest of his teammates with him.
"Players like him are hard to find, and usually if you have one you keep them. Juve will have a great defense. I cannot guarantee for sure, but certainly Lucio should increase Juventus' chances."
As well as spending a successful spell with Inter, Lucio also enjoyed title-winning stints in Germany with Bayer Leverkusen and Bayern Munich, and also lifted the World Cup with Brazil in 2002.
