This match precipitated the popularity of the new sport in Poland. Initially the rules and regulations were very simplified, with the size of the field and the ball varying greatly. Despite being discouraged by many educational societies and the state authorities, the new sport gained extreme popularity among pupils of various gymnasiums in Galicia. The first football teams were formed and in 1903–1904, four Lwów-based gymnasiums formed their own sport clubs: the IV Gymnasium for Boys formed a club later renamed to Pogoń Lwów, while the pupils of the I and II State Schools formed the "Sława Lwów" club, later renamed to Czarni Lwów. In the same season the Lechia Lwów was also formed. It is uncertain which of the clubs was created first as they were initially poorly organized; however, the Czarni Lwów are usually credited as being the first Polish professional football team. The following year, the popularity of the sport spread to nearby Rzeszów where Resovia Rzeszów was formed, while in the German-held part of Poland, the 1. FC Katowice and Warta Poznań were formed.
