During the 1920s the revenge spirit and sports tension were increasing every time the different teams in the Regional Championship had to meet. In 1923 Valencia became regional champions and could participate in the Copa del Rey for the first time in their history. The progress in the results of the team proved that they were able to become leaders of the football within the Valencian capital. Three or four years after its foundation, Valencia was already the most fearsome enemy for the rest of teams and their fanbase was growing.
