SURPRISE: Thai Coach Helps Laos Upset Thailand, Creating a Shock

By defeating Thailand U17 to top Group B, Laos U17 made a major surprise at the tournament under the guidance of a Thai coach.

Laos U17 just created the biggest shock at the 2026 Southeast Asia U17 Championship by defeating Thailand U17 with a 3-2 score on the match day of April 18. This result not only surprised experts but also drew attention from regional fans, due to the traditional gap between the two football systems.

This victory helped Laos U17 finish the group stage as the top team in Group B, earning 7 points after 3 matches with an unbeaten record. This is also the first time in over a decade, the young team from the Land of a Million Elephants has managed to reach the semifinals, since the last time in 2015. Notably, the figure behind this achievement is actually a Thai coach.

The person creating this special mark is Supachai Klangkrasae, the strategist currently leading Laos U17. The fact that a Thai coach helped the Laos team defeat his own homeland's national team left Thai public opinion quite surprised. Supachai is not an unfamiliar name, having worked for many years as a fitness coach in the Thai League.

In the past, he served as fitness coach and assistant at a series of clubs such as Muangthong United, Nakhon Pathom United, Khon Kaen United, Phitsanulok FC, and Sukhothai FC. In early 2025, Supachai began his international work journey by joining the Laos national team as a fitness coach, under the guidance of Korean coach Ha Hyuk Jun.

Just a few days before the 2026 Southeast Asia U17 Championship kicked off in early April, Supachai Klangkrasae was unexpectedly appointed as head coach of Laos U17. Despite the short preparation time, he quickly made an impact by helping the team build an effective playing style, achieving a record of 2 wins, 1 draw, scoring 7 goals and conceding only 5.

The peak of this journey was the dramatic 3-2 victory over Thailand U17, a team led by coach Sirisak Yodthaythai. Not only significant in terms of the result, the match also affirmed the progress of Laos youth football, and showed clear tactical influence from the Thai coach – who is writing a special story right in Southeast Asia.
