Before the season, he reportedly asked Spurs manager Mauricio Pochettino for permission to leave Tottenham in an attempt to get more playing time, but was instead given a chance to fight for his place at Spurs.
On 10 September 2016, Son scored two goals and created a third in his first appearance of the season, in a 4–0 win against Stoke City.
Son followed that performance up with a second brace, coming at Middlesbrough on 24 September, earning his team a 1–2 victory.
Upon equalling his league goal total from the previous season in 25 fewer matches, Son was hailed by Pochettino as "a different person – he's more mature and he knows the league and he's settled in fantastically now."
Son continued his excellent run of form with his fifth goal in five matches on 27 September in the Champions League.
Playing at CSKA Moscow, Son slipped a shot past goalkeeper Igor Akinfeev for the only goal of the match.
On 14 October, Son was named the Premier League Player of the Month for September, being the first South Korean and first Asian to receive the award.

Following the Christmas break Son continued to score the odd goal over the following couple of months and then on 12 March 2017 he scored his first Spurs hat trick in the FA Cup against Millwall in a 6–0 win.
In the same match, he was racially abused by a section of the Millwall fans who chanted "DVD" and "he's selling three for a fiver" whenever he touched the ball, referencing a stereotype towards east Asians.
He scored in the 2–0 victory away at Burnley on 1 April 2017, and four days later he scored in the 91st minute to put Spurs ahead at Swansea, in a game where they were losing 1–0 after 88 minutes and ended up winning 3–1.
A brace at home to Watford the following weekend brought his season total to 18 goals, 11 in the Premier League, his best ever goals return.
On 12 May 2017, Tottenham announced that Son had won the Premier League Player of the Month for April, the second time of his career and thus becoming the only player in 2016–17 to win the award 2 times.
On 18 May 2017, Son bagged a brace away to Leicester City as part of a 6–1 rout of their former title rivals.
With 21 goals in all competitions, Son joined Harry Kane and Dele Alli as the first trio of Spurs players with over 20 goals on the season.
