Kim Dong-jin (born 29 January 1982) is a former South Korean footballer who played as a full-back or a wing-back. He is currently the assistant coach of Hong Kong Premier League club Kitchee. Club career Kim started his professional career in Anyang LG Cheetahs (FC Seoul before 2004) in 2000, and spent his prime with them before joining Zenit Saint Petersburg. On 28 June 2006, he transferred to Zenit, following coach Dick Advocaat and Korean teammate Lee Ho. During his second season in Zenit, he helped his team to achieve their first Russian Premier League title by showing outstanding performance, and was named the second best left-back of the Russian Football Union. However, he couldn't show his ability after suffering a leg injury in the middle of the next season. Furthermore, he had a sudden problem with the blood circulation of his brain, and Zenit finally terminated his contract on 26 January 2010. He moved to Ulsan Hyundai and FC Seoul after other medical check-ups that found he was healthy enough to play, but he couldn't settle there. On 24 July 2019, Kim played Kitchee's friendly against Manchester City until being substituted in the 15th minute, and was handed a City shirt by Man City manager Pep Guardiola as strolling off the pitch. After the match, Kim retired from playing career, and became a coach of Kitchee. International career He was South Korea's left midfielder in the 2004 Summer Olympics, and helped Korea finish second in Group A by scoring one goal (against Greece) and two assists (both against Mali), consequently advancing to the next round. However, they were stopped by the silver medalist Paraguay. In 2004, Kim's performance against Germany while under Jo Bonfrère secured him the left-back or left midfield position (depending on the formation that was usually 4–3–3 or 3–4–3), which originally belonged to Lee Young-pyo. However, as Advocaat became the new manager of South Korea in November 2005, both Lee and Kim had to compete for the position. Since the two players proved to be highly influential to the national team, both players were rotated for the left back position during 2006 FIFA World Cup. During the 2008 Summer Olympics, he was summoned to join South Korean under-23 squad as an over-aged player. Despite his solid performance and a winning goal scored in the last game against Honduras, his team was eliminated in the first round.
