Ogbonna is preparing for his first campaign with the reigning Serie A champions after sealing a €13million switch from Turin rivals Torino earlier this month.
And Barzagli, who featured on 34 occasions at centre-back in the league last term, is happy to battle the 25-year-old for a place in Antonio Conte's plans.
"Ogbonna will help us for sure: when you want to improve the quality of a team, it's normal trying to buy great players," he told Gazzetta dello Sport.
"Angelo can become a leader, his presence will be important not only on the pitch but also in the dressing room: the fact of having a team-mate that can easily take your place will push each one of us to work harder and give 100 per cent.
"That's why I think that getting Ogbonna has been a great move. He's young and will give our defence some continuity in the coming seasons."
"My idea is never to give up anything, thinking to the World Cup right now is difficult, especially when you have a season full of important matches. Juventus is my priority, then, when the time comes, I'll think about the national team," he added.
