The Cong Viettel 0-1 CAHN: 90+4 minute goal decides Hanoi derby

As expected by experts, the Hanoi derby between The Cong Viettel and CAHN was dramatic until the final seconds. At Hang Day Stadium, CAHN earned a thrilling 1-0 victory thanks to a 90th+4 minute header from Stefan Mauk, despite being reduced to ten men from the 68th minute following Doan Van Hau's red card. The match was part of an important round in the LPBank V.League 1 2026/27 season, where both teams are in the title race. The first half was deliberately slow-paced. The Cong Viettel played cautiously, refraining from pushing high early to avoid conceding against a strong attacking opponent. Both sides deployed 4-3-3 formations, creating a stalemate with few breakthroughs. The turning point came in the 68th minute. CAHN left-back Doan Van Hau made a dangerous tackle on a The Cong player, prompting referee Ngo Duy Lan to consult VAR. After review, he issued a straight red card for violent conduct. CAHN were down to ten men, facing immense pressure from the hosts. However, the unexpected happened. Instead of collapsing, CAHN's defense, organized by coach Polking, remained highly disciplined. They switched to a 4-4-1 or 4-5-0 formation, clogging the central lanes and conceding only wide areas. Despite having a numerical advantage for over 26 minutes plus stoppage time, The Cong Viettel could not break through the crowded defense. Forwards Wesley Nata and Lucas Ribamar were isolated. Their clearest chance came in the 75th minute from a cross and header, but the ball went wide. Just when a 0-0 draw seemed certain, CAHN struck. In the 90+2 minute, substitute Le Van Do dribbled down the left flank and delivered a precise cross into the box. Midfielder Stefan Mauk arrived to head home from close range, silencing Hang Day Stadium. The 90+4 goal was decisive. Tactically, this was a victory of game management. CAHN executed a near-perfect defensive counter-attacking plan while a man down, ceding possession but keeping structure. In contrast, The Cong Viettel exposed a chronic weakness in breaking down deep defenses. Despite controlling possession and numbers, they lacked creativity and the ability to exploit spaces. Coach Popov's substitutions failed to produce the desired impact. This win carries enormous psychological weight for CAHN. They earned three crucial points in the title race while proving their resilience and squad depth. Conversely, The Cong not only dropped points at home but suffered a mental blow by losing while a man up. Coach Popov must solve the attacking puzzle to maintain top-group status. Doan Van Hau's red card will also have consequences. The full-back likely faces a minimum two-match ban under VFF regulations for violent conduct, forcing CAHN to adjust their defensive lineup in upcoming fixtures. Overall, the Hanoi derby delivered an improbable but fitting script. CAHN showed clear tactical identity and ambition under Polking, while The Cong Viettel must reflect on a match where all advantages were in their hands.
