The forward was in fine form in a 23 minute cameo for his nation.
Two of Tottenham's first team players who have played very little football because of injury recently were called up to international duty this week.
Firstly there was Nabil Bentaleb. Without a game since August he was called up the Algeria national team for upcoming games with Tanzania.
Then there was summer signing Heung-min Son. The South Korean was called up for action by the Taeguk Warriors but only returned to injury against Arsenal recently, before setting off on a lengthy round-trip with his country.
But judging by the first game in the South Korean international break Tottenham need not worry. In fact, it looks like it could do him some good.
He came on in the 67th minute of a win against lowly Myanmar in Suwon. He came on with the score at 2-0 and Son took the game by the scruff of the neck.
He bagged two assists in an excellent cameo.
Firstly he swung in a delightful free-kick which was headed in by defender Hyun-soo Jang, who atoned for a first-half penalty miss. He then played a wonderful one-two with midfielder Tae-hee Nam who then slotted home for 4-0.
Hopefully the run out and performance will help him improve his match fitness and confidence ahead of a return to London, after South Korea take on Laos on Tuesday.
