The Tottenham Hotspur player would not be risked during the international break unless he was fit, according to his national boss.
Son signed for Spurs from Bayer Leverkusen during the summer and he quickly impressed, scoring three goals and setting up another before suffering a foot injury that ruled him out for six weeks.
The 23-year-old has since returned to first-team action, coming off the bench against Arsenal at the weekend, and he is now set to take part in matches against Myanmar and Laos during the international break.
Given the player’s recent spell on the side-lines, Tottenham manager Mauricio Pochettino is unlikely to be too happy that one of his star-players is clocking up the air-miles in the days ahead, but Stielike has moved to quash concerns regarding Son’s fitness.
In comments published by the Mirror the South Korea coach said, “If Son wasn’t 100 per cent recovered his club team would have said something to us.
“Both the national team and his club team are monitoring his condition. I wouldn’t have picked (him) if I didn’t think he could play against Myanmar.”
Whatever the next two weeks hold for Son, Tottenham fans and management alike will be holding their collective breath, hoping he returns fit and firing for the tough domestic matches to come.
