After his time at Napoli, Altafini joined Juventus along with his former Napoli teammate goalkeeping legend Dino Zoff. Despite his advancing age, which often led him to be used as a substitute, Altafini was decisive in helping Juventus to win two more Serie A titles during the 1972–73 and the 1974–75 seasons. During the 1972–73 season, Juventus were point behind Milan, who were leading the Serie A table, before their final match of the season against Roma. Juventus were trailing at half-time, but Altafini scored a crucial equaliser (his ninth of the season), before Antonello Cuccureddu scored the late match winner. Milan were defeated in Verona, and Juventus's victory allowed them to capture the Serie A title. Another one of his most notable moments during his Juventus career was his goal against his former club, Napoli, during the 1974–75 season, at the age of 37. Before the match, Juventus were in first place, two points ahead of Napoli, in second place; Altafini came off the bench a few minutes before the end of the match, scoring the match winner in the 88th minute, helping Juventus to a 2–1 victory, which allowed them to increase their lead over Napoli and win the title; Altafini managed 8 goals in 20 appearances that season. A few days after the match, a banner with the writing "José core 'ngrato" was placed on one of the gates of the San Paolo stadium, referencing the fact that Altafini had previously played for the Neapolitan club.
