In the summer of 1979, he returned to Juventus, and remained at the club for four seasons, winning two consecutive Serie A titles in 1981 and 1982, and a Coppa Italia in 1983. His best season with the club was during the 1981–82 season, when he was given more first team opportunities following an injury to regular starter Roberto Bettega, and helped Juventus to the league title with his consistent and decisive performances. The arrival of Michel Platini and Zbigniew Boniek the following season, coupled with Marocchino's physical decline, saw him struggle to find space in the team, and he left the club at the end of the season.
