After the 1991–92 season finished in relegation for Cremonese, Rampulla moved to Juventus in 1992, where he enjoyed a highly successful 10-year spell at the club; he initially played as a starter, replacing Juventus's former legendary goalkeeper Stefano Tacconi, and subsequently as back-up goalkeeper for the remainder of his career, behind Angelo Peruzzi, Edwin van der Sar, and Gianluigi Buffon, and later as the reserve goalkeeper behind Andreas Isaksson and Fabian Carini, retiring from active football in 2002, following Juventus's Serie A title victory and Coppa Italia final defeat. Despite being predominantly a backup, he played matches in every competition for Juventus during almost every season of his Juventus career, in particular under Peruzzi during the mid 90s, when the latter was struggling with recurring injuries. During his time at the club, Rampulla won an UEFA Cup in 1993 (as a starter), a Coppa Italia in 1995 (as a starter), 4 Serie A titles, 2 Supercoppe Italiane (he replaced Peruzzi after he had been sent off in the 1995 edition of the tournament, contributing to his team's victory with several decisive saves), an UEFA Champions League, an UEFA Super Cup, an Intercontinental Cup, and an UEFA Intertoto Cup.
