Tun became the youngest ever player to feature in a FIFA recognised match, when, at 14 years and 93 days, he made his debut for
Myanmar against
Thailand in the
2000 Tiger Cup, a record he held for over 10 years before it was broken in November 2011 by Somali player
Abdinur Mohamud. He also scored in the match against Thailand, making him the youngest ever international male goalscorer - a
record which still stands. Since then, he has accumulated 13 international caps. ==Coaching career==
