Juventus have won the title back to back since 2013 and could claim it once more this term, according to the 25-year-old.
“It will be difficult for Udinese to compete with Juventus and I don’t think the players Juventus are signing are even because of the Italian Serie A," Badu told Class FM.
“The players Juventus had before the arrival of the new ones can do the work and I think they brought in the new faces to concentrate more on the Uefa Champions League.
“They will always remain favourites to win the league and what they have shown in the last five years really tells that.
“I know for 100 per cent they will win the league but I want my brother Kwadwo Asamoah to win the Champions League too,” he added.
Badu, who boasts of 93 appearances for Udinese since joining the team in 2010, has extended his stay until 2020 and believes his hard work has paid off.
“I am very happy with the new contract that I got from the club. That means the club appreciates my hard work and I'm very happy. I just want to remain calm and concentrate on this campaign because for the past two years, it has been difficult for Udinese. We even battled relegation at a point,” he added.
Udinese will travel to Milan on Sunday to lock horns with AC Milan at San Siro.
