Rossi confirmed his growth during the 1978 World Cup tournament, gaining international fame as one of the world's best strikers. Playing for Italy as a central striker, he would sometimes switch positions with the two other forwards, going to his original right wing position. Right winger Franco Causio, a two-footed player, would go left, and Italy's tall left winger Roberto Bettega would go to the center. This simple stratagem, made possible by the technical quality of all three players, created havoc for opposing defences, and Italy showed an entertaining offensive style of play in the tournament. Rossi totalled three goals and four assists as Italy finished in fourth place in that World Cup. He was named as part of the team of the tournament for his performances, and he also collected the Silver Ball as the second-best player of the World Cup. Rossi's goal in Italy's opening 2–1 group win of the tournament against France, on 2 June 1978, was also his first goal for Italy.
