Seo Jung-won

After South Korea's head coach Pim Verbeek resigned in July 2007, Seo entered the list for the vacant managerial position for the national team. From 2009 to 2010, he and his former national teammate and close friend, Hong Myung-bo, worked together as a part of the coaching staff for the South Korea under-20 and under-23 team. In 2010, Seo joined the coaching staff of the senior team under manager Cho Kwang-rae. Since 2012, he has been a member of the coaching staff of the Suwon Samsung Bluewings, becoming the club's manager in 2013. Under his tenure, the Bluewings finished the 2014 and 2015 seasons as runner-ups and won the Korean FA Cup in 2016. The FA Cup Final was notable as it featured Suwon Samsung Bluewings and FC Seoul, one of the biggest K League rivalries. The match went into extra time after FC Seoul scored a goal in the 93rd minute, leveling the aggregate score to 3–3 over two legs. After a scoreless extra time period, the final was decided over penalties where Suwon Samsung Bluewings won 10–9. This was Seo's first silverware of his managing career.

In February 1999, he returned to South Korea and joined Suwon Samsung Bluewings. He led the heyday of Suwon for six years with 12 trophies, including two Asian Club Championship. Lastly, he played for Austria Salzburg and SV Ried in the Austrian Bundesliga. He was also selected as the Austrian Footballer of the Year by two Austrian media Kurier and Sportwoche in 2005.

After serving his military service in Sangmu FC, Seo longed to play in Europe, and even left for Germany and the Netherlands to participate in tryouts. In the summer of 1997, he succeeded to contract with Portuguese Benfica and appeared four games with a goal in the pre-season. However, the Korean FA didn't approve of his employment to qualify for the 1998 FIFA World Cup with him. In January 1998, joining a French club Strasbourg, Seo became the first South Korean player who played in the Ligue 1. He successfully spent his first season by contributing to their survival in the Ligue 1, but he was pushed to the bench next season after his manager was replaced. He participated in the 1998 FIFA World Cup although he got chickenpox, transferred from his son, but showed unnoticeable performance with the team's elimination in the group stage.

Seo played for South Korea under-23 at the 1992 Summer Olympics in Barcelona, and went into the opponents' goalpost with a goal during the match against Sweden. He was reportedly offered a contract from FC Barcelona and other European club giants after his performances at the Olympics, but he stayed South Korea to serve a two-year mandatory military service. He also played for South Korea at the 1994 FIFA World Cup, and scored the equalizer against Spain.

Seo Jung-won (born 17 December 1970) is a South Korean former football player and current coach. A winger who had explosive pace, he was nicknamed the "Nalssaendori", meaning an agile man in South Korea.
