Vietnam Football's Depth and Financial Puzzle: From AFF Cup Glory to the Asian Cup Threshold

At minute 90+3, Vietnam Tri stadium was blazing. A cross from Van Thanh on the right wing curled into the penalty area, and substitute striker Tien Linh headed the ball into the Thai goal. The whole country erupted. The 2026 AFF Cup trophy belonged to Vietnam after a six-year wait. In the stands, tens of thousands of red flags with yellow stars waved. In the press conference, coach Kim Sang-sik smiled humbly: "This is a victory of the Vietnamese spirit." But even in that moment of happiness, I saw a bigger question ahead: how will this team not only rule Southeast Asia but stand firm against Asian powers at the 2027 Asian Cup? To answer, we must look back at the journey through numbers, squad structure, and the financial foundations silently shaping the future. Vietnam has enjoyed a rare decade: from outside the FIFA top 120 to top 100, two AFF Cup titles (2026, 2026), reaching the final round of World Cup qualifiers in 2026, and appearing in Asian Cups 2026 and 2026. Sporting success and operational sustainability are two different stories. In the 2026 AFF Cup, the squad relied heavily on the 2026-2026 generation. The average of 16.4 players used per match was the highest in the tournament, revealing a lack of depth in several positions. Young players barely get league minutes: U23 players average 18.2 matches per season in V-League, lower than Thailand's 27.4 and Malaysia's 24.1. Financial constraints force clubs to depend on benefactors. The V-League's broadcast revenue is only about 80 billion VND a year. Without transparency and youth investment, the success could fade. Tactically, Vietnam's defensive style worked in Southeast Asia but was insufficient in the 2026 Asian Cup. A contrarian angle: the AFF Cup title may breed complacency. The key is to reform finance, youth development, and player exports. Vietnam needs 15-20 players abroad to raise standards. The summer of 2026 is decisive. The national team must start integrating young players now. Sustainable development is the only way forward.
