At the end of the 1928–29 season Alessandria was admitted to the first edition of Serie A tournament (1929–30, 6th place) and finally inaugurated the new stadium. In the early 1930s, several players left the club, still tied to amateurism, to migrate to large centers; Carcano, Ferrari and Bertolini signed for Juventus and Allesandria greatly lost its potential, not gaining anything but middle-ranking positions.
