Cercle Brugge became a member of the Royal Belgian Football Association in 1900 and were awarded matricule number 12. The same year the club moved from their football field in Sint-Michiels, which was owned by De Frères, to a pitch in Sint-Andries, which offered better facilities and was closer to Bruges' main railway station in 't Zand square. Cercle achieved their first success in the 1902 Henri Fraeys Cup, defeating Olympique Iris Club Lillois (the predecessor of Lille OSC) and US Tourcoing. After winning another few friendly cups Cercle achieved their first big success, winning the national title in the 1910–11 season. Cercle ended a single point ahead of their main rivals FC Bruges, after their confrontation on the season's last matchday ended in a 1–1 draw.
