Coach Kim Sang Sik has a historic opportunity with the Vietnam national team. If he leads the team to victory in the 2026 ASEAN Cup, he will achieve a remarkable milestone. This would mean winning two separate tournaments by defeating Thailand in the finals. Such a feat is something that former coach Park Hang Seo never accomplished. This potential success would place Kim Sang Sik in a unique position in Vietnamese football history. It creates a compelling narrative regarding the legacy of the two managers. Ultimately, the 2026 tournament will determine if Kim can surpass this specific record.
