Rajamangala has become the "fertile ground" for Coach Kim Sang Sik and a new golden chapter in Vietnamese football.

Rajamangala Stadium appears to have become a beautiful part of Coach Kim Sang Sik’s coaching journey with Vietnamese football. On Thailand’s largest stadium, which always imposes immense pressure on visiting teams, the Korean coach has twice stunned the home side.

At the beginning of 2025, the Vietnam national team led byCoach Kim Sang Sikdefeated Thailand 3-2 to win the 2024 ASEAN Cup. Later that year, also at Rajamangala, Vietnam U22 again beat Thailand U22 in the final by the same score to claim theSEA Games 33 gold medal. This coincidence is no longer just luck but a clear sign of his coaching prowess.
