PPDA Decline and the Fitness Trap: Why High Pressing Is Running Out of Room in V.League

In the last three rounds of V.League 1, the PPDA of a title-chasing club dropped from 9.8 to 7.2. Looking at the number, many rushed to conclude that this team is pressing more aggressively. Sitting through those 270 minutes, I saw the opposite: heavy legs of a group that had run out of battery, forced to push up because they no longer had the strength to drop back into position. As a former player, I don't need to watch the tape to know who is running in the wrong place. And that wrong running, in V.League, is repeating at an alarming frequency. Over the past two seasons, more and more V.League clubs have switched to high pressing. In theory, this is welcome progress. But when you place that model into the specific context of Vietnamese football, it collides with three walls: hot and humid climate, a dense fixture list, and uneven pitches. All three are variables a training plan copied from Europe cannot fully account for. I once wrote an article nobody read. Three years later, it became my lesson plan. That piece pointed out that pushing the full-backs high in a 4-3-3 made the team collapse in midfield, and I proposed switching to a 3-5-2 with inverted wing-backs. What I learned lay not in the conclusion but in the method: never impose a system on an environment without re-measuring its operating cost. In V.League, the operating cost of high pressing is far higher than in temperate leagues. A pressing team must run more, but a player's recovery capacity in 30-34 degrees Celsius with high humidity is lower. The result is that pressure can only be sustained for the first 20-25 minutes, after which the system collapses on its own. PPDA falls in the first half but spikes in the second — the classic sign of a fake pressing system. What is interesting is that many teams still win in the early phase, which makes the coaching staff believe the model is working. They look at the scoreline and ignore the process. This is where data must be read correctly. If the data is right, the gap between first-half and second-half pressure will be an earlier indicator than any league table. The second wall is the fixture list. A V.League season with three matches in eight days does not allow any club to sustain high pressing throughout. Teams with thin squad depth are forced to choose: either press and collapse late in the season, or sit deep and protect points. Most choose the latter, but do so reluctantly. The third wall is the pitch. A long ball on a poor surface becomes a weapon that destroys any organised pressing intent. A high-pressing team needs the opponent to pass short so it can intercept, but when the opponent deliberately goes long, the entire pressing structure becomes meaningless. V.League has too many teams willing to go long, and that makes high pressing an expensive gamble. What is worth noting is that many teams still believe simply signing one hard-running central midfielder will solve the problem. But pressing is a system, not the story of one individual. One hard-running link cannot compensate for ten others who have run out of battery. Here I want to talk about the transfer market. I read a deal not through its price tag, but through where the player will stand in the system. A team that wants to press high needs players with a fitness base and the ability to read situations, not a flashy attacking star. But the V.League market prices by goals and fame. The consequence is that many clubs buy expensive strikers and then force them to press — a double waste. Worse, the loan-with-obligation-to-buy mechanism is strangling smaller clubs. They are forced to take on big clubs' players at high wages, then must buy them outright at season's end, while the budget does not allow it. Small clubs forever nurture semi-finished products for the giants, while the giants collect players who have been forged for free. This is a structural problem, beyond the scope of a single deal. World Cup 2026 taught me one thing: hesitation is what ruins every plan. A club that realises its pressing model does not fit but waits until the end of the season to change has already waited too long. Decisions must be made when the data is just enough to act, not when everything is already clear. Amid a chaotic season, what a strategist needs most is the calm of an outsider. Here a counterintuitive angle appears. xG has been overused in recent V.League analysis. Many use xG to conclude which team deserved to win, but xG cannot explain refereeing decisions, cannot measure a player's actual form in harsh conditions, and does not account for a team deliberately sitting deep. A match where the underdog parks the bus will produce an artificially low xG. Reading xG while ignoring context is a way of deceiving yourself with numbers. Data remains necessary, but it must stand beside a real human detail. After every number, I always ask: how did the person involved experience that moment? A player covering 11.5 km per match in hot and humid conditions carries a tired body on his back. Only when you see the person behind the number does the analysis carry weight. In 2026, everything collapsed. I stood up and rebuilt from the rubble. When leagues were suspended, I analysed data from matches played without crowds and realised one thing: when the context changes, the system must change too. Vietnamese football is at exactly that moment — a shift in context demanding clubs redefine how they play. What I want to track next round lies in the PPDA gap between the two halves, rather than the scoreline. If a team can hold its pressing structure from minute 20 to minute 80 in this month's heat, that is a sign of a genuine fitness base. But if that gap keeps widening, we will know that the pressing revolution in V.League is merely a beautiful illusion on the tactics board.
