 Under new manager Edmondo Fabbri, Albertosi became a regular in Italy's squad; he played his first World Cup with Italy in England 1966, where they were surprisingly and disappointingly knocked out in the first round.In the 1970 World Cup in Mexico, Albertosi was once again named Italy's starting goalkeeper, due to his excellent and consistent performances throughout the season with Cagliari.He started in all of Italy's matches, and was involved in the so-called "Game of the Century", when Italy played West Germany in the semi-final of the tournament; despite conceding three goals in this match, and some moments of hesitation and indecisiveness, Albertosi later won praise for a string of decisive acrobatic saves.
