Pohang Steelers

The club was founded on 1 April 1973 as Pohang Iron & Steel Company FC, or simply POSCO FC. Initially a semi-professional club, they turned professional in the 1984 season and changed its name to POSCO Dolphins. A year later they renamed as the POSCO Atoms. In 1986 they won their first Championship, and enjoyed a great spell of domination in the league; between 1985 and 1998 they were continuously in the top four of the K League.

In 1995 the club was renamed again, becoming the Pohang Atoms. This name change was an attempt to further strengthen local ties with the region, and in 1997 they adopted their current name, the Pohang Steelers. The team won the Asian Champions Cup in 1997 and 1998.

In the 2000s, the club struggled near the bottom of the table, but bounced back to the forefront of South Korean football by winning the first stage of the 2004 K League Championship. The club qualified for the final Championship match of the 2004 season, but lost 4–3 on penalties to Suwon Samsung Bluewings.

In 2007, the club won the Championship play-off by beating Seongnam Ilhwa Chunma, who finished in first place in the regular season of the K League. Pohang won the first leg 3–1 at home, and then traveled to Seongnam for the second leg game, recording a 1–0 victory to seal a 4–1 aggregate triumph. The Steelers had ended the K League season in fifth place, but then defeated Gyeongnam FC, Ulsan Hyundai Horang-i, Suwon Samsung Bluewings and finally Seongnam Ilhwa Chunma in the play-offs to win the championship.

Pohang again made the play-offs in the 2008 season by finishing the season in fifth place, but were knocked out in their play-off game by Ulsan Hyundai after the penalty shoot-out. However, the club fared much better in the 2008 Korean FA Cup. After beating Seongnam Ilhwa Chunma in the quarter-finals, Pohang knocked out Daegu FC in the semi-finals and then defeated Gyeongnam FC in the final to ensure qualification for the 2009 AFC Champions League.

In the 2009 AFC Champions League, the Steelers defeated Umm-Salal of Qatar 4–1 on aggregate in the semi-finals to advance to their first ever AFC Champions League final. The Steelers defeated Saudi club Al-Ittihad 2–1 at the National Stadium in Tokyo, Japan to claim the title. For the 2009 K League season, Pohang once again qualified for the play-off phase of the league by finishing the regular season in second place, equal with FC Seoul on points, but ahead on goal difference. The Steelers had a bye to the semi-finals, but lost to Seongnam Ilhwa Chunma. Nonetheless, their regular season placing saw them qualify for the 2010 AFC Champions League Group stage.

Following the conclusion of the 2009 K League season, at the 2009 FIFA Club World Cup in December, the Steelers finished in third place after defeating Mexican side Atlante 4–3 on penalties.
