V-League 2026-25: When New Teams Enter and Old Systems Must Adapt

The match between Nam Dinh and Hai Phong in Round 7 of V-League 2026-25 ended with a 2-1 victory for the home side. The notable moment was not the final goal, but in the 34th minute — when Nam Dinh's foreign striker unexpectedly dropped deep to receive the ball in the center circle, completely breaking Hai Phong's three-line pressing structure. This is a microcosm of a trend unfolding across the league: newly promoted teams are forcing established clubs to rewrite their operating methods. This context did not appear from nowhere. After Thép Xanh Nam Dinh was promoted from the First Division in the 2026-23 season, the club signed three foreign players and two foreign coaching assistants in just two transfer windows. The strategy targeted three weak positions — right center-back, central midfielder, and striker — showing the management did not want to build from scratch but wanted to purchase a complete framework. This approach raises a question: can a team buy tactics, or can they only buy players? Returning to the match against Hai Phong. Under coach Chu Dinh Quang, Hai Phong had built a fixed pressing system over three seasons: the right center-back pushes high to create an offside trap, two wide midfielders press the touchlines, the striker tracks the opponent's build-up center-back. This is a tight structure, but it operates on an implicit assumption: the opponent will play through their center-backs. When Nam Dinh's foreign striker dropped deep into his own penalty area to receive the ball, he rendered Hai Phong's center-back redundant in the first pass. Match statistics clearly show this: Nam Dinh had 47% possession time in the opponent's half, higher than their previous season average of 38%. Hai Phong completed 14/21 pressing attempts, a 66.7% success rate — 12 percentage points lower than the previous season. The average distance between Hai Phong's defensive and midfield lines in the first half was 18 meters, compared to 12 meters in their previous wins. The visitors had to compress to fill the gaps, and when compressed, they lost space for counter-attacks. The individual highlight belonged to Nam Dinh's young midfielder Phan Xuan Manh. Born in 2026, 1m72 tall, playing as a left midfielder in a 4-2-3-1 formation. In 78 minutes, Manh completed 6/8 passes into space between opponent lines — passes analysts call "third-man passes," passes that bypass the first defensive line but don't enter the penalty area. These passes require players to read both teammate positions and opponent distances. Manh is not a goal scorer, but he is the orchestrator that Nam Dinh's system needs to maintain pressure on Hai Phong. The contrarian view — which many commentators have overlooked — lies in coach Chu Dinh Quang's decision. He did not change formation at halftime despite the system clearly having problems. Instead, he pushed both full-backs 5 meters higher and asked central midfielder Dieu Duy Trung to drop deeper to act as "bait." This is a risky adjustment: it transforms a defensive player into a tempo controller, and it only works if that player has enough experience not to make passing errors. Dieu Duy Trung, 29, has played over 150 V-League matches. He completed 11/13 passes in the second half and helped Hai Phong temporarily regain balance in the 58th minute. This adjustment reveals a principle I have drawn from years of following leagues: sometimes coaches don't change the system because the system is wrong, but because the opponent has found a way to exploit a blind spot in that system. Completely changing formation at halftime could panic players accustomed to the old rhythm. Coach Quang's solution — keeping the framework, changing the line height — is a calculated compromise. However, the match ended with Nam Dinh's victory, and that victory was not accidental. The goal in the 71st minute came from a quick counter-attack: Hai Phong's goalkeeper had to leave the penalty area to clear, the pass failed, and Nam Dinh's foreign striker positioned himself between the two opponent center-backs. The distance between Hai Phong's two center-backs in that situation was 9 meters — wider than the ideal 6 meters according to optimal defensive spacing research. A player with speed and positioning ability will always find that gap. The lesson from this match is not only for Hai Phong. It shows the V-League is entering a phase where newly promoted teams, with abundant financial resources, can buy both players and tactical philosophies from outside. Clubs like Hai Phong, or Thanh Hoa with their characteristic possession style, are facing the question: should they maintain the system built over many years, or accept changes to adapt to new opponents? The answer, perhaps, lies in young players like Phan Xuan Manh — those who do not carry the burden of team history and can play football in ways the old system cannot control. In swimming, I learned that young athletes are often faster in the first strokes because they are not bound by habits. Football is the same. And V-League 2026-25 is proving this through each round.
