South Korea U-23 Football Team Faces Vietnam in Asian Games Quarterfinal

Men’s Football Quarterfinal Setup Against Vietnam

Head coach Lee Min-sung’s under-23 squad faces Vietnam at 7:30 PM at the Mizuho Park Rugby Stadium in Nagoya. The team advanced as Group D winners with a 2-0 record, opening with a 4-1 victory over Qatar and a 2-0 win against Saudi Arabia. Iraq’s late withdrawal reduced Group D to three nations, saving the squad a match and preserving player conditioning. Winning the group also allowed South Korea to avoid powerhouse regional contenders like Uzbekistan, Japan, and North Korea on the path to the final.

The quarterfinal opponent presents a tactical score to settle. Vietnam reached this stage as Group C runners-up with a 1-1-1 record. Earlier in January 2026, a South Korean under-23 side fell to a Vietnamese squad led by South Korean manager Kim Sang-sik via a penalty shootout in the AFC U-23 Asian Cup third-place match. Kim now focuses exclusively on Vietnam’s senior national team due to overlapping FIFA international windows, leaving the under-23 side under senior assistant coach Dinh Hong Bin. Several of Vietnam’s core players were also pulled to the senior roster, weakening their under-23 depth.

Roster Strength and Tactical Adjustments

South Korea boasts a significant personnel advantage. Lee deployed North-Central World Cup veterans alongside elite European-based talent, including wildcards Lee Ki-hyuk of Gangwon FC, Eom Ji-sung of Swansea City, and Yang Hyun-jun of Celtic, alongside Bae Jun-ho of Stoke City and Kim Ji-soo of Brentford. Head-to-head history favors South Korea, holding an undefeated 6-0-4 record in under-23 matches against Vietnam, with last year’s shootout loss officially recorded as a draw.

Despite the favorable metrics, lingering tactical vulnerabilities require attention. During the 2-0 group stage win over Saudi Arabia, Lee’s squad struggled against deep-lying defensive blocks and physical pressure until scoring two headers. Passing fluidity and set-piece execution remain works in progress, with heavy reliance on flank attacks and individual brilliance. KBS commentator Lee Young-pyo noted after the Saudi fixture that no opponent is easy, emphasizing that player focus must remain absolute and consistent across every match phase. Meanwhile, Lee Min-sung stated that the team will adopt a stable approach for the knockout rounds.

Path to the Semifinals and Historical Caution

A regulation victory over Vietnam propels South Korea into a September 30 semifinal against the winner of the China-Thailand match. Historical under-23 records against those potential opponents lean heavily in South Korea’s favor, standing at 13-3-4 against China and a spotless 7-0 against Thailand.

Tournament history warns against complacency. South Korea has frequently entered Asian Games campaigns as heavy favorites only to stumble against underdogs such as Thailand in the 1998 Bangkok Games, Iran in 2002 in Busan, Iraq in 2006 in Doha, and the United Arab Emirates in 2010 in Guangzhou. Compounding that caution, Lee Min-sung’s side struggled prior to the tournament with a modest 8-win, 4-draw, 7-loss record amounting to a 42 percent win rate in international friendlies and qualifiers, keeping the technical staff on high alert.
