In the 1933–34 season, he scored 16 goals for Milan, finishing the season as the fifth highest scorer in Serie A, leading to his selection by manager Vittorio Pozzo to the national team for the 1934 FIFA World Cup on home soil. Italy won the title, although Arcari did not make a single appearance throughout the tournament; consequently, he is one of only four players in Italian national team history to become World champion while never being capped.
