But despite Allegri allowing defensive lynchpin Leonardo Bonucci to join AC Milan in a deal reportedly worth €42million, De Rossi thinks Juve are frontrunners to claim yet another Scudetto.
"When facing Juventus in the league, you know the real difficulty lies in their group: the defence is strong and their other departments are well-organised," De Rossi told a press conference ahead of Roma's International Champions Cup games against Tottenham and Juve. "They have no weaknesses, so it won't be easy against them.
"Would I be happy if someone else won the title, such as Napoli? Absolutely not. In the case Juve do not win it, I want us to be the team that do. It's difficult to face Juve, but we're trying and I want to keep trying for two more years."
Roma head into the new season without iconic midfielder Francesco Totti, who retired at the age of 40 to become a director at the club.
"I always feel him, he will never be on his own," De Rossi added. "But we have to move on, he will face a new situation and we will also go forward, it's nothing problematic, although things will be different without him. He's a great friend."
