With the arrival of Giovanni Trapattoni in 1976 as coach, Bettega found himself becoming the main frontman of the "bianconeri" in the late 70s; the former player to take this position, Pietro Anastasi, moved to Internazionale in the summer of that year, and Bettega partnered with his replacement, Roberto Boninsegna, leading the team to notable domestic and European success during this period, including back to back Serie A titles, a Coppa Italia, and an UEFA Cup triumph; Juventus also reached the European Cup final during the 1972–73 season, as well as the Intercontinental Cup final, and managed a semi-final finish in the 1979–80 European Cup Winners' Cup.
