Son's exclusion from the squad will put an end to a potential club-versus-country dilemma, a situation many clubs struggle to deal with.
With Son not being part of the Olympic squad for South Korea means he will be available for selection when Tottenham Hotspurs begin their Premier League campaign on Sunday August 15 against champions Manchester City.
Son, who bulged the net 17 times in thirty-seven games with ten assists last season will be expected to do more for Spurs under a new manager Nuno Espirito Santo.
With the absence of Son from the squad, Valencia midfielder Lee Kang-in, the youngest member of the squad at 20 has been included and could avoid military service by winning an Olympic medal.
The age for the Olympic football tournament which is for players under 23 has been raised to 24 this year because of COVID-19 outbreak which has postponed the tournament by one year.
A close source to Son disclosed that the 24-year-old feels disappointed to have been excluded from the Olympic squad after almost getting into trouble with Tottenham Hotspurs board for an approval to represent his country.
"Son understands the coach has the right to make roster choices the way he sees fit," the source said, asking for anonymity. "But he's still disappointed, because he went to so much trouble to get Tottenham on board."
