Prior to representing the senior Italian side, Zoff had won a gold medal with the Italy under-23 side at the 1963 Mediterranean Games. On 20 April 1968, Zoff made his senior debut for Italy, playing in a 2–0 win against Bulgaria in the quarter finals of the 1968 European Championships, in Naples. Zoff ended up being promoted to starting goalkeeper over his perceived career rival Enrico Albertosi during the tournament, and Italy proceeded to win the European Championship on home soil, with Zoff taking home a winners' medal after only his fourth international appearance, keeping two clean sheets, and winning the award for the best goalkeeper of the tournament. Zoff was left out of the Italian starting eleven in the 1970 World Cup, however, and was Albertosi's deputy throughout the tournament, as Italy went on to reach the final of the World Cup, and was defeated 4–1 by Brazil. He returned to the starting line-up, however, ahead of Albertosi, in Italy's disappointing 1974 World Cup campaign, during which they would be eliminated in the first round.
