The first derby match between the two Milanese rivals was held in the final of the Chiasso Cup of 1908, a football tournament played in Canton Ticino, Switzerland, on 18 October of that year; the "Rossoneri" won 2–1. While Inter and Milan faced each other sporadically in the early years, the rivalry has been renewed annually since the inaugural 1926–27 season of the Divisione Nazionale, the first truly national Italian league. The two teams have played each other at least twice a year since then.
