Nguyen Quang Hai leads V-League assist chart: What tactics make him shine?

The attack of CLB Cong An Ha Noi is having an explosive season. In last weekend's Hanoi derby, Nguyen Quang Hai provided two assists, helping his team win 3-0 against Viettel. The second goal came from a skillful narrow-angle play, but more notable was how Quang Hai read the situation before the ball touched his foot. He did not run into available space; he created space by pulling the opposing defender out of position. That was a subtle off-the-ball movement, what I call a 'silent move' in football.

But this article is not to praise a beautiful play. This article is about a reality I have witnessed over 53 years of watching football: Vietnamese coaches rely too much on reactive tactics rather than building proactive systems. When opponents play a low block (mass defence), many teams give up or pass sideways harmlessly. But Quang Hai, with the support of coach Polking, did differently. The story below is not just about a player, but about how a tactical system can unlock individual talent.

From the sideline, I see the whole match. Seven months without football, seven months of constantly asking why. People watch the players run. I watch the whole block shift. These are three signature lines I use to dissect every match. And when applied to the case of Quang Hai and CAHN this season, I see something interesting: this team is playing football without 'heavy theory' – similar to how a chess player avoids main variations to target the psychological weakness of the opponent.

Context: The low-block defensive system – 'nemesis' of Vietnamese attacking football

In V-League, most teams when facing CAHN choose to defend en masse with two layers (low block 4-4-2 or 5-4-1). This is a safe tactic, like a chess opponent avoiding 2.c4 to skip heavy theory. It is not ambitious, but extremely dangerous if the attacking team lacks a Plan B. In the first 5 rounds, CAHN often struggled against lower-ranked teams – they held 65% possession but only had 2 shots on target. Coach Polking admitted: 'We lacked ideas when the opponents put 10 men behind the ball.'

That was when I recognized a tactical gap: Vietnamese coaches focus too much on high pressing and fast transitions, but neglect the 'build-up phase' in the final third. They are like a chess player who only attacks the center, not knowing how to shift to the wings. And the story of Quang Hai, along with the tactical course I will analyze, is the answer to this problem.

Tactical analysis: 'Plan B for low block' – a course by coach Van Quyen?

Here I want to introduce a tactical product I believe is necessary for Vietnamese football: the video course 'Breaking the Low Block' developed by former national player and coach Le Van Quyen (currently training SLNA youth team). The course consists of 6 videos, each 20-30 minutes long, focusing on 6 specific attacking scenarios against mass defence. The scenarios include: flank attacks with overlapping full-backs, central penetration through through-balls, and especially 'silent movement' – what Quang Hai demonstrated.

I previewed this course and found it addresses a real problem. Coach Van Quyen doesn't just give exercises; he dissects actual V-League matches to point out teams' blind spots. For example, in the second video, he analyzes how Thanh Hoa got torn apart 3 times in 10 minutes simply because their full-backs advanced too late – a classic tactical error.

But there is a problem: the course is too broad, lacking depth. 6 videos for 6 scenarios means each scenario gets only 20 minutes. In comparison, a dedicated course on overlap attacking usually takes 6-10 videos alone. This makes me doubt the real quality. However, at a price of 299,000 VND, it is still a useful tool for young coaches or players wanting to improve tactical thinking. As I always say: 'Data is never narcissistic. The system doesn't lie, but you can only hear it when the data is thick enough.'

Contrarian view: 'The low block is not dangerous, but complacency is the enemy'

One thing the course does not mention, but I consider important: Vietnamese teams often play a low block with a 'containment' mentality, not with a clear tactical intention. They stand 10 men in front of the box, but without pressure, no offside trap, no selective pressing instructions. This turns a system that is supposedly 'not ambitious' into 'extremely dangerous' – but dangerous for themselves, because they lose the ball in dangerous areas and get hit on the counter.

People watch Quang Hai's assist and say 'class', but I watch the space left by the opposing defender. That is not an individual error, that is a system error. And this is the blind spot that 90% of commentators miss. They talk about technique, but I talk about organization. They watch the player run, I watch the whole block shift.

Takeaway: What awaits CAHN and Quang Hai in the upcoming stretch?

Quang Hai is in top form, but I worry about one thing: if opposing teams start studying how CAHN breaks the low block, they will adjust. Football has no permanent formula. A successful system today can be decoded next week. The question is: is coach Polking flexible enough to change? Or will CAHN fall into a 'tactical trap' like many other teams have? I am sixty-nine. I still learn from the young. Football does not retire.

And for coach Van Quyen, if he wants his course to be truly valuable, he needs to expand its depth, don't stop at 6 videos. Show me the numbers – success rates of each attack type, average time to score after a specific combination. Data is never narcissistic, and it will tell everything.
