An Ik-soo

An became a founding member of professional club Ilhwa Chunma in 1989 despite starting football very late. Furthermore, he became one of the best defenders in the K League, helping Ilhwa win three consecutive titles from 1993 to 1995. In 1994, he played five friendlies for the South Korea national football team prior to the 1994 FIFA World Cup due to his performances. He was also selected for the national team for the 1994 World Cup, but didn't appear in World Cup matches. However, Ilhwa sold An to Pohang Steelers after the 1995 season because they thought he was old enough to deteriorate his ability, although he led them to Asian Club Championship title and K League title that year. An was named the MVP of the Asian Club Championship after defeating his former club Ilhwa in the final of the next tournament.

An was part of the South Korean national football team in 1994 FIFA World Cup.
