Early opponents included the "Aurora" of Busto Arsizio, the "Libertas" of Gallarate, the Luino, the Unione Sportiva Milanese, the Ausonia, and Inter.
The club took the first steps on the Italian league ladder by entering the Lega Regionale Lombarda in 1914, and the first official championship saw the Varesini playing in their original colours of purple and white silk.
It was renamed in September 1950 to Stadio Franco Ossola, in honour of a player who had transferred from Varese to Torino Calcio and died in the 1949 Superga air disaster.
Varese, a town not far from Milan, is highly regarded by various athletes who dress "bianco-rosso" (white-red) thanks to Military Territorial Compartments (between the most known players Giuseppe Meazza).
In 2001, after financial conflicts between entrepreneur Gianvittorio Gandolfi and sponsors SiViaggi and CIT, the Turri family arrived at the club, bringing a series of innovations.
Club President Peo Maroso and general manager Luca Sogliano, son of Riccardo and also a former player, decided to install a new first-team coach from within.
Varese finished second in Girone (Group) A of League Pro Prima Divisione and qualified for promotion play-offs at next season.
Varese defeated Benevento in semi-final and Cremonese in final and returned to Serie B after 25 years of absence with making second consecutive promotion.

In the 2017–18 season, Varese Calcio started without a president and, in November, manager Salvatore Iacolino resigned due to the club's financial crisis.
