They finished as runners-up in 2002 and 2003, and started to emerge as a strong force. In 2005, with the return of two key players, Yoo Sang-chul and Lee Chun-soo, they qualified for the championship playoffs. In the play-off semi-final, they beat Seongnam Ilhwa 2–1, and in the final, they beat Incheon United 6–3 on aggregate, with a hat-trick from Lee Chun-Soo in the first leg.
