As Son took his tally to nine goals and five assists in his last 10 matches across all competitions, the winger also continued Spurs' habit of striking late.
His goal was the fourth winner Spurs have scored in the last 10 minutes of their 29-match run.
Two of their defeats in that period were also settled by opposing goals in or after the 80th minute.
