Park Hang-seo, the head coach of Kanchanaburi FC, made headlines for his heated reaction during a friendly match against Eastern SC in Kanchanaburi, Thailand. The match, held on July 29, 2026, ended with Kanchanaburi winning 2-0. However, the game was marred by a confrontation that sparked the coach's anger.

The incident occurred in the first half when a Kanchanaburi player was fouled, leading to a scuffle between players from both teams. In response, Park Hang-seo stormed onto the field, visibly upset, and pointed angrily at the opposing players while his assistant, Lee Jung-soo, attempted to calm him down and guide him back to the technical area.

As the match progressed, Park's frustration continued to show. After another foul against his team near the penalty area, he looked towards the Eastern SC coaching staff, raising his hands in disbelief and making gestures that suggested his dissatisfaction with the officiating.

Kanchanaburi FC took to their fan page to express excitement about the match, encouraging fans to describe the game in three words. Many responses included references to Park Hang-seo, highlighting his passionate demeanor and connection with the supporters.

Park Hang-seo is known for his fiery temperament, a trait that has been evident throughout his coaching career. Previously, while leading the Vietnam national team, he had several confrontations with referees and opposing coaches, including a notable incident with assistant coach Sasa Todic after a World Cup qualifying match in 2019.

After stepping down from his role with Vietnam in January 2023, Park took on the role of Vice President of the Korea Football Association but resigned after the national team's early exit from the 2026 World Cup. He officially joined Kanchanaburi FC on July 10, 2026, with the goal of promoting the team to Thai League 1.

In the lead-up to the friendly matches, Kanchanaburi FC had seen success, winning against Thonburi United and Samut Songkram City before facing Eastern SC. The team is set to begin their Thai League 2 campaign against PT Satun FC on September 6, 2026.
