Kim Ju-chan was born on March 29, 2004.[1] He has one older sister.[2] His family moved to Suwon when he was six years old.[3] His father was an aspiring footballer, which influenced him to start playing the sport in 2010.[2][4] Kim transferred to Seryu Elementary School after being scouted by one of its coaches.[3] He attended Chung-Ang University Middle School and was enrolled at Chung-Ang University High School.[5] After one year, he transferred to Suwon High School and played as a striker for its football club.[2][6] Leading up to his final year in high school, he was notified of Suwon Samsung Bluewings' interest in him by his agent.[5]
Senior career
In 2022, Kim was recruited by Suwon Samsung Bluewings as a free selection.[7] He made his debut professional appearance in the first round of the 2023 K League 1 season as the team faced off against Gwangju FC.[8] In May, he scored his debut goal in the fourth round of the 2023 Korean FA Cup, leading his team to a 1–0 victory against Daegu FC and advancing it into the quarterfinals.[6]
Kim's first K League 1 goal came two months later in his twelfth appearance and first full game, where he scored the team's third goal in the 45th minute on the second half of the match, defeating Ulsan Hyundai FC 3–1.[9][10] He was selected as one of the K League 1 R23 MVP Best 11 due to his performance.[11] He scored a goal in the following round against Gangwon FC and his team won 2–1; Suwon Samsung Bluewings was granted a second consecutive victory. Having ranked last among the twelve teams in the league, Kim was credited in part for the rise in his club's ranking to number eleven after the matches.[12][13]
