Son said winning a title in Europe with Spurs “felt like I had achieved everything I possibly could”.
He made his Tottenham debut in September 2015 and went on to make 333 Premier League appearances.
He scored 127 times in the league – level with former Chelsea striker Jimmy Floyd Hasselbaink at 16th in the league’s all-time scorers list, above the likes of Dwight Yorke, Steven Gerrard and Ian Wright.
Son formed a memorable attacking partnership with Harry Kane, now at Bayern Munich, and the pair hold the record for the most goal combinations in the Premier League.
The pair registered a record 47 combinations, Son scoring 24 goals to Kane’s 23. In a prolific two-season period – 2020-21 and 2021-22 – they linked up 21 times for goals.
Son became the first Asian player to win the Premier League golden boot, sharing the title with Liverpool’s Mohamed Salah with 23 goals in the 2021-22 season, and a year later was the first from the continent to reach 100 Premier League goals.
He featured in the Champions League final against Liverpool in 2019 – which the Reds won 2-0 – and took over as club captain from Hugo Lloris in August 2023.
“I need a new environment to push myself. I need a little bit of change – 10 years is a long time,” Son added.
“I spent a lot of time reflecting on whether I wanted to experience football in a different environment, and I had those conversations with myself over and over again.”
Son also provided 101 assists in all competitions and holds Spurs’ record for Premier League assists with 71.
He has also made the sixth-most appearances in the history of the club – behind only Cyril Knowles, Pat Jennings, Gary Mabbutt, Steve Perryman and Glenn Hoddle.
