While at Perugia, he managed 13 goals in Serie A during the 1979–80 season, also helping the club to the round of 16 of the UEFA Cup. During the season, however, he was involved in the infamous 1980 betting scandal known in Italy as Totonero, and as a result of this Rossi was disqualified for three years, although this was later reduced to a two-year ban. As a result, Rossi missed out on the 1980 European Championship with Italy, where the team once again finished in fourth place, on home soil. Despite the ban, Rossi always claimed to be innocent, and stated that he had been a victim of an injustice.
