Aged 12, Lee caught the attention of FC Barcelona after he finished as the top scorer in the 2010 Danone Nations Cup, one of the most prestigious youth football tournaments.[4] He joined Barcelona's youth academy, La Masia, and scored 39 goals in 29 appearances during his first season.[5] He was also named the best player in four youth tournaments: Torneo Canillas,[6] Memorial Gaetano Scirea,[7] Trofeo San Bonifacio,[8] and Gabala Cup.[9] He was nicknamed the "Korean Messi" after showing his talent.[10]
However, he was banned from playing in the regular season for three years until his 18th birthday by transfer regulations of FIFA.[4][5] On 13 March 2016, he made his senior debut for the B team.[11]
Club career
Hellas Verona
On 31 August 2017, Lee joined Serie A club Hellas Verona on a four-year deal, for a fee of €1.5 million. Barcelona retained the option to repurchase him until 2019 for an undisclosed fee.[12]
On 24 September, he made his Serie A debut for Verona in the second half of the game against Lazio.[13] On 6 May 2018, he scored his first Serie A goal in an away match against Milan, but his team lost 4–1.[11]
Verona was relegated to the Serie B by finishing the league in 19th place. He scored one goal and provided two assists during 27 appearances in the 2018–19 Serie B. Verona was promoted to the Serie A by winning the promotion play-offs,[14] but he was excluded from Verona's plan for the next season.
Sint-Truiden
On 30 August 2019, Lee joined Belgian First Division A side Sint-Truiden.[15] He was excluded from the list of the squad for twelve consecutive matches, and this situation caused much controversy in South Korea.[16][17] His name was on the list for the first time against Genk on 29 November,[18] and he made his Belgian league debut against Waasland-Beveren on 26 December.[19] He finished his first season due to early termination of the Belgian league caused by the COVID-19 pandemic after making only four appearances.[20]
On 13 September 2020, he scored his first and second goal for Sint-Truiden against Royal Antwerp, but his team lost 3–2 despite his two goals.[21] However, he failed to score in six games where he played as a starter excluding a game against Antwerp, and his team also did not get a victory at the same time.[22] When he was being excluded from the squad again, some South Korean journalists recommended playing in South Korea to him.[22]
On 1 February 2021, Lee joined Primeira Liga side Portimonense on a six-month loan deal with an option to buy.[23] He had difficulty in leaving special impression on the new club. He left Portimonense after the end of his contract.
Suwon FC
In December 2021, Lee returned to his hometown of Suwon, signing with K League 1 side Suwon FC on a multi-year deal.[24]
Lee still showed weak physical strength, pace and defensive skills, which had been followed by his failure in Italy and Belgium,[25] but his accurate shots and momentary movements stood out in South Korea.[26] In his first K League 1 season, he became the third highest scorer without a penalty, and was selected as one of the four best left wingers, who were nominated for the K League Best XI.[27]
In his second season, Lee struggled somewhat due to his weaknesses grasped by opponents,[25] but helped Suwon avoid relegation by scoring the most goals among team members.[28] He received an offer from Seire A club Frosinone in the middle of the season,[29] but was more cautious about his challenge in Europe after the hardship at Sint-Truiden.[30]
For the first half of the 2024 season, his third season at Suwon, Lee dominated the league and already reached double-digit goals. Another club in the same league, Jeonbuk Hyundai Motors, offered him the league's highest salary in the summer transfer window.[31]
Jeonbuk Hyundai Motors
On 24 July 2024, Lee joined Jeonbuk Hyundai Motors on a four-and-a-half year deal.[32]
In the 2014 AFC U-16 Championship, he showed overwhelming performances, leading South Korea to the final. He scored winning goals against Malaysia and Thailand in the group stage.[34] Afterwards, in the quarter-finals, he scored all two goals in a 2–0 win over Japan, and left a memorable scene. He destroyed Japan's defense by dribbling for about 50 meters, scoring his second goal.[35] In the semi-finals against Syria, he recorded one goal and four assists.[36] He became the tournament's best player and top goalscorer, although his team lost the final to North Korea.

In a friendly against Honduras just before the 2018 FIFA World Cup, Lee made his senior international debut and showed impressive performance including an assist.[41] He was selected for the World Cup team, playing two World Cup matches as a substitute.
Lee was named in the South Korea under-23 squad for the 2018 Asian Games in Jakarta-Palembang. In the round of 16 against Iran, he scored his first goal of the tournament.[42] In the semi-finals against Vietnam, he led South Korea to a 3–1 victory with two goals and one assist. In extra time of the final, he scored the crucial opening goal, contributing to a 2–1 victory over Japan. He won a gold medal after the final.[43]
Lee was selected to the Korean national team roster for the 2026 World Cup qualifiers in October 2024 and returned to the national team after 5 years and 4 months. Lee was selected as a replacement due to injuries to Hwang Hee-chan and Um Ji -seong. He needed to join the training urgently, so he arrived at the training using standing room on the train.[44]
