Mergers

In 1921, Internazionale Napoli absorbed a minor Neapolitan club called Pro Napoli. During 1922 the main two rival Neapolitan clubs; Naples FBC and US Internazionale Napoli merged into one due to financial pressures. They first took the name Foot-Ball Club Internazionale-Naples, commonly referred to as FBC Internaples. Internazionale Napoli gave to the club the famous "N" crest and the white shorts; this was coupled with the light blue featured on the Naples FBC shirts. The merged club was seen by media and fans to be a continuation of Internazionale Napoli rather than a new club; the merged club played its games at the Terme di Agnano rather than Naples FBC's Campo del Poligono and kept Internazionale Napoli's nickname of ''Gli Azzurri'' (The Blues) rather than ''I Blucelesti'' (The Navy Blue and Sky Blues) used by Naples.''Il Messaggero'' del 10 novembre 1922, p. 2.
