The Tottenham Hotspur forward came on for 27 minutes and bagged two assists v Myanmar.
Tottenham Hotspur had some serious and understandable concerns ahead of the international break regarding two of their first-team players.
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 despite only recently returning to action after being out of action since September through injury.
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 63rd 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, one apiece for Hyun-soo Jang and Tae-hee Nam, as South Korea came out of the game with a comfortable 4-0 triumph and Tottenham's summer signing - well he barely broke a sweat.
Here is how some fans reacted to his performance for South Korea ...
Just want to thank @theKFA for using Heung Min-Son for only 27 mins today. You got a comfy 4-0 win & he looks to come away no worse for wear— Steve Rothgeb (@FuzzyWarbles) November 12, 2015
