The South Korean star would remain an eligible Under-23 player next August.
Next summer the big event in football is the European Championships in France.
However, there is another big tournament taking place - the football at the summer Olympics.
16 teams will be vying for the Olympic gold medal in football - which was won by Mexico in London in 2012.
But Premier League teams could certainly do without their players heading to Brazil. The tournament runs from the 3rd August to the 20th August - just at the beginning of the football season.
Tottenham Hotspur might indeed have to make do without one of their own for that period.
"He is an extraordinary player and is the best Korean footballer at this moment.
"Under the condition that we are going to the Olympics, there is no hesitation to pick him.
"If he can do well, as he has been doing, we should bring him to the Olympics. He will contribute big for our team."
Son will still be eligible as an Under-23 player in the summer and Korean fans would love to see the Tottenham Hotspur star in action at the Olympics.
The Olympic Games in football is not taken seriously by many nations but South Korea is not one of them. They won the bronze medal at London and would like to go further in Rio de Janeiro.
The good news for Tottenham is that Son turned down the chance to play for his country in 2012 and there is every chance he would do the same should South Korea qualify for next summer's tournament.
