At club level, Rossi was also a prolific goalscorer for Vicenza. In 1976, he was signed to Juventus from Vicenza in a co-ownership deal for a world record transfer fee. Vicenza retained his services, and he was the top goalscorer in Serie B in 1977, leading his team to promotion to Serie A. The following season, Rossi scored 24 goals, to become the first player to top the scoring charts in Serie B and Serie A in consecutive seasons. Rossi made his debut for Juventus in 1981, and went on to win two Serie A titles, the Coppa Italia, the UEFA Cup Winners' Cup, the UEFA Super Cup, and the European Cup.
