Son joined Hamburger SV at the age of 16 and debuted in the German Bundesliga in 2010. In 2013, he moved to Bayer Leverkusen for a club-record €10 million before signing for Tottenham for £22 million two years later, becoming the most expensive Asian player in history.
Widely regarded as one of the best wingers in the world and also one of the best Asian players in European football history.
Son was also the first Asian player in history to score more than 50 goals in the Premier League.
While at Tottenham, Son became the top Asian goalscorer in both Premier League and Champions League history. In 2019, he became the second Asian in history to reach and start a UEFA Champions League final after fellow countryman Park Ji-sung.
He is considered an icon in his home country and in Asia, and was nominated for the Ballon d'Or in 2019, the highest-ever rank so far by an Asian player.
On 2 January 2021, Son scored his 100th goal for Tottenham in the 3–0 win against Leeds.
In the 2021–22 season, he won the Premier League Golden Boot award with 23 goals, becoming the first Asian player to do so.
