Van Tung and the Lesson from Ninh Thuan: When the U21 Generation Gradually Replaces U23

On March 19, 2026, Ninh Thuan stadium held only about 3,200 spectators — far below its 15,000-seat capacity. But those present witnessed something rare: a 21-year-old scored twice in 15 minutes late in the match, helping Thép Xanh Nam Dinh win 3-1. His name was Nguyen Van Tung. Before the match, no professional analyst had listed him among the players to watch. This was not the first time a young face unexpectedly emerged in the V-League. But what makes Tung's case worth pausing on is his trajectory — from Saigon FC's youth team, to a First Division club, then back to the V-League as a regular starter — reflecting a trend that analysts in Vietnam have mentioned repeatedly but never measured with concrete data: the 2026-2026 generation, the U21 cohort, is gradually taking over from the U23 generation that received more systematic investment since 2026. The context for this trend began forming at the 2026 National U21 Championship. That tournament featured 11 teams, with Viettel and Hanoi FC fielding nearly full youth squads. Viettel won the title, but the more notable story lay in players who didn't make the first-team cut yet caught the attention of lower-division clubs. According to VFF statistics, 34% of participants in the 2026 U21 Championship signed professional contracts within 18 months of the tournament — significantly higher than the 19% rate of the U23 cohort in 2026. Van Tung joined Thép Xanh Nam Dinh at the start of the 2026-2026 season on a three-year contract. According to VuaBong sources, his monthly salary at the time of signing in August 2026 was 50 million VND, with a 15 million VND bonus for each V-League goal. At 21, he is one of 12 players born in 2026 currently playing in this season's V-League — compared to 8 in the previous season. Vietnam's youth development system has made visible progress over the past five years. As of February 2026, 17 of 20 clubs in the V-League and First Division operated their own youth academies, according to VFF's Youth Development Board. However, quality gaps between these systems remain significant. An internal survey accessed by VuaBong shows only 6 of 17 clubs have dedicated coaching staff for the U15-U19 age groups. The rest use part-time coaches — an issue the professional community has raised for several seasons. One detail I paid particular attention to: among the 12 players born in 2026 currently in the V-League, 4 were previously released from major clubs' youth systems before age 18. Van Tung was one of them. He failed Viettel Scout's physical requirements during recruitment in 2026. His story is not an exception — it reflects a structural problem: Vietnam's development system evaluates young players too early based on physicality and height, overlooking technical qualities that are harder to measure but often determine long-term careers. The Vietnam U23 team at the 2026 U23 Asian Cup qualifiers in Qatar was a notable case study. That squad included many players expected to become the backbone of the national team. Performance results showed a larger-than-expected gap between the technical foundation honed at youth level and the demands of professional competition at a higher tier. Meanwhile, some younger faces from lower divisions, like Van Tung, demonstrated faster adaptation to V-League pace when given consistent playing opportunities rather than being trapped within expectation circles. Thép Xanh Nam Dinh is one of the few V-League clubs that actively builds mechanisms to promote young players to the first team. In the 2026-2026 season, the club registered 6 under-23 players in the official squad, up from 3 the previous season. Head coach Vu Quang Vinh, in an interview with VuaBong in January 2026, said he aimed for at least 2 players born in 2026 to play from the 60th minute onward in each home match. "I don't need them to be extraordinary immediately," he said. "I need them to get used to real match atmosphere." This approach runs counter to the general trend in Southeast Asian leagues, where many clubs increasingly rely on foreign players and older athletes to secure positions. In Thai League, the average age of starting lineups in the 2026-2026 season was 27.4 — higher than the V-League's 25.8 in the same season. This gap reflects two different philosophies, and at least 3-5 more years will be needed to assess which is more sustainable for Vietnamese football. Something I have observed across multiple seasons: the current U21 generation benefits from a denser match schedule compared to their predecessors. The National U21 Championship has been held annually since 2026, while between 2026-2026 the U21 National Tournament was held irregularly. The irony is that the policy of reducing national youth tournaments in 2026-2026 created the 2026-2026 U23 cohort with concentrated investment, but their conversion rate to the first team was actually lower than the U21 generation who received less attention but played more at club level. The counterintuitive angle here is that concentrated investment in the U23 generation may be backfiring. When a young player enters the national youth system too early, performance pressure from the youth national team level gradually replaces the process of accumulating real-match experience. Young Vietnamese footballers are often strong in concentrated training environments but struggle when entering the V-League — which has no script, no VAR, and demands continuous ability to handle unexpected situations. The V-League does not lack young players. The 2026-2026 season recorded 87 under-23 players who have taken the field at least once — a record since the league professionalized in 2026. What it lacks is a system that allows them to develop at their own pace rather than being forced into the club's performance timeline. Van Tung was fortunate to find Coach Vinh, who has both the authority and patience to wait for him to mature. But how many other Van Tungs are sitting on benches at other clubs, waiting for a moment that may never come? Ninh Thuan stadium on the evening of March 19 remained empty, but the cheers of roughly 3,000 spectators were enough to create a real moment. Van Tung celebrated his second goal by running to the touchline where Coach Vinh stood. No hug, no kiss. Just a touch of hands. Enough for a young player to know that this mentor is seeing him — truly seeing him — not an idealized version pre-built in expectations. Vietnamese youth football does not need another ideal Van Tung. It needs more systems wide enough that every Van Tung, regardless of being cut from any recruitment, has a way back. Currently, that path is still under construction.
