Koo Ja-cheol (Hangul: 구자철; Korean pronunciation: [ku.dʑa.tɕʰʌl] or [ku] [tɕa.tɕʰʌl]; born 27 February 1989) is a South Korean footballer who plays as midfielder for Bundesliga club FC Augsburg and the former captain of South Korean football team.
Blessed with technique and vision, Koo "has an uncanny ability to find the back of the net, often displaying a knack to charge into the opposition penalty box unsighted."
Koo started football at age ten when a nearby elementary school opened its football club. During his early youth career, he mostly played as a defender, often taking sweeper role. However, he wasn't particularly outstanding and the fact he suffered from anemia also hindered him from gaining attention. In 2006, as a member of Boin High School, Koo participated in the Baekrok High School Football Competition that is annually held in Jeju Island. Leading Boin High School to a runner-up place with an outstanding performance, he grabbed the attention of Jung Hae-seong, who was then the manager of Jeju United.
In 2007, Koo was selected by Jeju United in the K-League draft. He failed to make an impression in his first two years at Jeju due to numerous injuries. However, he slowly broke into the first team, mostly playing as a defensive midfielder. In January 2010, he was reportedly invited by Blackburn Rovers for a trial, but the move didn't happen. He spent a great season in 2010 at Jeju instead, driving his club to an unprecedented runner-up position. His contribution also enabled him to gain personal honors, as he received the 'FAN'tastic Player award and the Top Assist award and was included in the Best XI.
On 30 January 2011, Koo Ja-cheol successfully moved to VfL Wolfsburg during the winter transfer window, signing a three-and-a-half year contract for an undisclosed fee. On 12 February 2011, Koo made his VfL Wolfsburg debut against Hamburger SV, coming on as a substitute in the 64th minute in the 0–1 home defeat.
Loan to Augsburg
On 31 January 2012, he moved on loan to the league rivals FC Augsburg. During the loan period, he scored five goals in 15 appearances, and played a significant part in helping Augsburg escape relegation in their maiden season in the Bundesliga.
In his second season at Augsburg, Koo was plagued by injuries but still helped the club survive relegation in the limited games he played in. In December 2012 he was involved in an on the field altercation with Bayern Munich's midfielder Franck Ribéry in a 2–0 2012–13 DFB-Pokal loss. After a disputed free kick he confronted Ribéry and touched his face, in response Ribéry slapped Koo. Referee Thorsten Kinhöfer gave Koo a yellow card and sent off Ribéry. Bayern Munich director Karl-Heinz Rummenigge demanded that the ejection be overturned, while Bayern's coach Jupp Heynckes blamed both Koo and Ribéry, stating that although Koo had provoked Ribéry the latter should learn to not react under pressure.
During the 2012 London Olympics, Koo played as a central midfielder in the Korean national team. He appeared in every game in the tournament, and scored the second goal during the second half of the bronze medal match against Japan, securing a 2–0 victory for Korea. The South Korean team won the bronze medal in football for the first time in its Olympics history and in doing so, became the second Asian team in the Olympics men's football to reach the semi-finals.
He was named captain of the national team ahead of the 2014 FIFA World Cup, and scored in a 4–2 defeat to Algeria in the team's second group match. He was selected for the 2015 Asian Cup and played a decisive role in South Korea's opening match, a 1–0 victory over Oman, and was named man of the match. In the match against Australia, Ja-cheol suffered an injury and missed the remainder of the tournament.

Koo likes to go shopping in his spare time in Germany. He is currently the honorary ambassador for The Republic of Korea Air Force. Koo is also a close friend with his teammate Ki Sung-yueng, and they like to display their friendly, humorous conversations on Twitter. Ki revealed on the Korean talk show Healing Camp, Aren't You Happy that Koo has a nickname called "Koogle Georim" or 구글거림 in Korean because of his sometimes goofy way of talking. On 24 June 2013, Koo married a Jeju woman three years older than him at the Sheraton Grande Walkerhill Hotel.
