In 2005 summer, Giannichedda left Rome and joined Juventus FC, where he struggled for playing time under manager Fabio Capello, often being deployed as a substitute along with Manuele Blasi behind starters Emerson and Patrick Vieira. He only made 24 overall appearances in his first year, winning the league title; the team was stripped of the accolade, however, due to the club's involvement in the 2006 Italian football scandal and, as a result, was also relegated.
