Vietnam National Team's Personnel Crisis: An Unsolved Puzzle for Coach Kim Sang-sik

The Vietnam National Team is facing one of its most difficult periods in years as a series of key players suffer injuries and declining form. Coach Kim Sang-sik, expected to bring Vietnamese football back to regional prominence, is grappling with an unsolvable personnel puzzle ahead of crucial matches in the 2027 Asian Cup qualifiers. According to the Vietnam Football Federation (VFF), captain and center-back Nguyen Que Ngoc Hai had to leave the field early in his club Cong An Ha Noi's most recent V-League match due to a thigh muscle injury. MRI results revealed a Grade II muscle tear, requiring at least four to six weeks for full recovery. This is a massive loss as Que Ngoc Hai is not only the defensive leader but also the one who ignites the team's spirit in difficult moments. Not only Que Ngoc Hai, but center-back Bui Tien Dung of Viettel FC is also racing against time to recover from a recurring knee injury. Meanwhile, Do Duy Manh of Ha Noi FC has missed most of the V-League 2026-2026 first leg due to calf issues. Vietnam's defense, long considered a solid foundation for years, is facing the risk of a serious crisis as all three top center-backs are not at peak fitness. In midfield, Nguyen Hoang Duc has yet to regain his peak form since transferring to Cong An Ha Noi. Statistics from V-League 2026-2026 show Hoang Duc averaging only 1.2 key passes per match, a significant drop from 2.4 in the 2026-2026 season when he played for Viettel. His duel success rate has also declined, winning only 43% of contests compared to 58% previously. This is a worrying signal as Hoang Duc is considered the irreplaceable playmaker of the national team. Midfielder Nguyen Tuan Anh of Hoang Anh Gia Lai is also in the twilight of his career and can no longer maintain high-intensity play. Persistent injuries throughout his career have eroded the physical capacity of the 2026-born player. Meanwhile, Do Hung Dung, though still maintaining consistency for Ha Noi FC, has turned 33 and can no longer cover the entire midfield area as he did at his peak. In attack, star striker Nguyen Tien Linh is in decent form, scoring 12 goals in 15 matches at V-League 2026-2026 for Binh Duong FC. However, the gap around him is concerning as Nguyen Van Toan can no longer maintain his explosive pace, while Nguyen Quang Hai has yet to fully adapt to his new role in Cong An Ha Noi's tactical system. Notably, the wave of overseas Vietnamese players is becoming a focal point for media and fans. Coach Kim Sang-sik is reportedly closely monitoring the performances of several Vietnamese-heritage faces playing in Europe. However, the naturalization and integration process for these players still involves complex legal procedures, requiring time and close coordination between VFF and their parent clubs. Tactically, Coach Kim Sang-sik is known for his proactive attacking philosophy, prioritizing high pressing and quick transitions. However, this philosophy demands peak fitness and high synchronization across all lines. With the current injury situation and declining form, implementing this philosophy has become extremely difficult. In recent matches, Vietnam has frequently been exploited behind the midfield line, especially in the second half when physical capacity drops. Data analysis from recent matches shows Vietnam's PPDA (passes allowed per defensive action) increased from 9.8 to 13.2, reflecting less effective pressing. The team's average xG (expected goals) per match also dropped from 1.65 to 1.12. These are alarming numbers indicating problems in both attack and defense. On the coaching side, Coach Kim Sang-sik is under considerable pressure from public opinion. Domestic media continuously question the Korean strategist's ability to turn things around. Some experts believe he needs to boldly give opportunities to young players like Nguyen Thanh Nhan, Khuat Van Khang, and Nguyen Dinh Bac, who are impressing at V-League. In the regional context, Southeast Asian football is witnessing the strong rise of Thailand and Indonesia. Thailand, with players competing in J-League and K-League, is gradually asserting its position as the region's number one. Indonesia, with its aggressive naturalization policy, is also creating a new wave. In this context, Vietnam's stagnation is seen as a worrying signal for its continental ambitions. Financially, VFF has committed to increasing investment in the national team for 2026-2028, including hiring top fitness experts and improving facilities at the Vietnam Youth Football Training Center. However, these resources need time to take effect, while crucial matches in the 2027 Asian Cup qualifiers are imminent. Vietnam's upcoming matches in the 2027 Asian Cup qualifiers will be a true test for both Coach Kim Sang-sik and the current squad. With the current personnel situation, securing a spot in the finals will be a significant challenge. Vietnamese football fans are waiting to see if the coaching staff can find breakthrough solutions to overcome this difficult period. In the immediate future, Coach Kim Sang-sik needs to solve the personnel puzzle flexibly, maximize available resources, and may have to adjust his tactical philosophy to suit the reality. This is a period that tests the coach's mettle as well as the fans' patience. Vietnamese football has overcome many difficulties before, and this time is no exception. But to achieve that, unity across the entire system is needed, from VFF leadership to the coaching staff, every player, and the fans.
