Thể Công Viettel Suffers Crushing 0-5 Defeat Against FC Seoul in AFC Champions League Two

The journey of Vietnamese representative Thể Công Viettel in the continental arena suffered a catastrophic setback on October 28, as they endured a resounding 0-5 defeat at the hands of South Korean powerhouse FC Seoul. Playing in front of their home supporters at Hàng Đẫy Stadium during the third matchday of the AFC Champions League Two 2026/27 group stage, manager Velizar Popov’s side was thoroughly outclassed across all departments. This heavy loss marks Thể Công Viettel’s third consecutive defeat in the tournament, pushing the team dangerously close to an early elimination and compounding what has already been a deeply challenging period for the club across both domestic and international fronts.

A Masterclass in Efficiency by the K.League Champions

Entering the fixture just days after celebrating their coronation as champions of the K.League 1, FC Seoul arrived in Hanoi with a reputation for tactical discipline, technical prowess, and blistering pace. Despite suggestions that the visiting side might rotate their squad following their domestic title win, manager Kim Gi-dong deployed a formidable starting lineup that quickly dismantled the host’s defensive structure.

The tone for the evening was set as early as the 8th minute. A swift, incisive counter-attack caught the Thể Công Viettel backline napping, allowing forward Moon Seon-Min to calmly slot the ball past goalkeeper Văn Việt to open the scoring. The early breakthrough galvanized the visitors, who continued to apply relentless pressure.

In the 21st minute, Anderson Oliveira doubled FC Seoul’s advantage. The Brazilian attacker showcased exceptional close control, weaving past retreating defenders before unleashing an unstoppable, ferocious strike into the back of the net. Thể Công Viettel’s defensive frailties were further exposed before the half-hour mark. In the 29th minute, Hwang Do Yun rose uncontested to direct a powerful header past Văn Việt following a precise cross from the left flank. Just five minutes later, in the 34th minute, Cho Young Wook capped off a brilliant team move by finding space on the right side of the penalty area to make it 4-0. The scoreline at halftime reflected a dominant, flawless exhibition of attacking football by the South Korean champions.

Second Half Resignation and Missed Consolation Chances

Trailing by four goals, Thể Công Viettel attempted to alter their tactical approach after the interval, pushing higher up the pitch in search of a foothold in the match and a potential consolation goal. However, this aggressive posture left them increasingly vulnerable to transitional attacks.

Barely nine minutes into the second half, Leonardo Ruiz compounded the hosts’ misery by notching FC Seoul’s fifth goal of the night in the 54th minute, capitalizing on a sharp turn and clinical finish inside the box.

Despite the overwhelming deficit, Thể Công Viettel created a few notable scoring opportunities in the second period. Midfielder Trung Hiếu rattled a shot just wide of the post in the first half, while substitutes such as Việt Hưng and Văn Tú came close with long-range efforts and near-post headers. In the 65th minute, FC Seoul were reduced to ten men when defender Yazan Al-Arab received his second yellow card, followed by a red card, for a reckless challenge on Phan Tuấn Tài. Yet, even with a numerical advantage for the final twenty-five minutes, the Vietnamese side lacked the clinical edge required to breach Baek Jong Beom’s goal. Substitute Wesley Nata and other late arrivals missed promising chances, sealing a scoreless night for the home side as the match concluded at 0-5.

Broader Implications and Mounting Pressure on Coach Popov

The 0-5 defeat leaves Thể Công Viettel anchored near the bottom of Group E with just one point from their opening three fixtures, while FC Seoul has rapidly rebounded from a slow start in the continental campaign. For manager Velizar Popov, the pressure is mounting exponentially. The team is currently enduring a difficult winless streak across competitions, reflecting struggles both in the V-League—where the club sits 12th with only 4 points after 5 rounds—and on the Asian stage.

Popov’s tactical system, typically known for its high-energy pressing and defensive resilience, has looked increasingly fragile against elite continental opponents. The inability to organize a cohesive defensive block against technical masters like FC Seoul exposes deep-seated structural issues within the squad, particularly concerning depth and defensive concentration.

With three matches remaining in the group stage, Thể Công Viettel’s path to the knockout rounds is mathematically narrow. They must secure maximum points in their upcoming fixtures, starting with away legs and return matches, while relying heavily on favorable results elsewhere in Group E. As the club returns to domestic duties, the technical staff faces an urgent task to restore player confidence, mend defensive vulnerabilities, and salvage what remains of a season threatening to unravel prematurely.
