The club was founded in 2021 after the Luce family, previously owning amateur club Città di Sangiuliano (founded in 1968 as Società Sportiva Borgolombardo), which they led from Seconda Categoria to Eccellenza, acquired Serie D club NibionnOggiono and relocated it to San Giuliano Milanese under the new denomination of Sangiuliano City Nova; for their debut season, due to Italian Football Federation regulations involving relocated clubs, they had to play their home games in Nova Milanese.[2][3]
