The Silent Revolution: Troussier and the High-Pressing Puzzle at U23 Vietnam

They sat in the dressing room of Viet Tri Stadium, silent enough to hear the ceiling fan. The friendly match against U23 Thailand ended 1-1, but no one talked about the last-minute equalizer. They talked about failed presses, about the vast gaps between the two center-backs when the line pushed up. I stood in the corridor, watching coach Troussier scribble in his old notebook. He didn't shout. He quietly circled one number: 12 – the number of times U23 Vietnam lost possession in their own half due to uncoordinated pressing.

The context of this match was not merely a friendly. It was a test for a tactical system Troussier is quietly implanting into Vietnamese football: high pressing with a fluid 3-4-3 formation. Unlike Park Hang-seo – who prioritized compact defending and rapid transitions – Troussier wants his players to win the ball back immediately after losing it, pushing the line high to smother the opponent from the front. But this demands high fitness, tactical discipline, and situational awareness. And in Viet Tri that night, I saw a team taking its first wobbly steps on a new path.

Core Analysis: The Numbers That Speak

Based on my experience covering matches, high pressing cannot be implemented overnight. Look at the data: U23 Vietnam attempted 18 tackles, but only 6 were successful in the opponent's third. Passing accuracy in the middle third was only 72%, 8% lower than the team's average under Park. This shows the players are not yet comfortable receiving the ball under pressure, lacking the necessary communication between lines. The key issue is not the tactical intent, but the execution capability – something that can only improve with time and repetition.

I recall Incheon United's 2026 training sessions under coach Lee Ki-hyung, when they tried to shift from counter-attacking to possession. The dressing room was silent after defeats. But after six months, the team began to operate more smoothly. With U23 Vietnam, I see similar signals: players like Nguyen Van Toan made intelligent runs to draw defenders, creating space for teammates. Hoang Duc's goal came from a high turnover – exactly what Troussier wants.

Contrarian View: The Misunderstanding of Rigidity

Many say Troussier is too rigid, imposing a single tactical system on a generation used to counter-attacking football. But I believe the opposite is true. What looks like rigidity from outside is actually a foundation-building process. If you've ever stood in a dressing room, you'd see the players are not resisting; they are struggling to understand. They need a clear template before they can improvise. Troussier is providing that template. The issue is time.

Look at how U23 Thailand operates under coach Ishii – they went through a similar crisis when shifting from defense to pressing. But after two years, they became the best possession-based team in Southeast Asia. Football is not magic. It is patience with a process. And Troussier, with his extensive experience in Africa and Japan, understands this better than anyone.

Internal Signals & Next Steps

A source in the U23 Vietnam coaching staff told me Troussier has asked the players to focus on three key drills this month: (1) coordinated movement when losing the ball, (2) one-touch passing in the central corridor, and (3) building baseline fitness. These are the first bricks of a larger building. If U23 Vietnam can maintain effective pressing for 60 minutes instead of the current 30, that will be a huge leap.

Takeaway: An Open Question

The dressing room does not lie. Only outsiders need embellishment. That night, as the players left the pitch, I saw Hoang Duc sitting alone, watching video replay on his phone. He said nothing, but his eyes said it all: they believe in the process. And the only question left is: will the fans have enough patience to wait for the results of that process?
