When football analysis is hollow: A lesson from the 'insufficient data' report for Vietnamese fans

I just read a two-thousand-word analysis with all the grand headings: tactics, finance, media pressure, systemic risk. Its only conclusion was a dry line: 'N/A – Insufficient information.' The entire sensationalist machinery produced not a single verifiable observation. Sounds familiar, doesn't it? That is exactly the intellectual diet of quite a few football programmes on Vietnamese television every weekend. We as V.League fans are often led by empty post-match commentary: Team A won because of 'fighting spirit', Team B lost because of 'lack of composure'. Nobody talks about the gap between midfielders, nobody measures successful pressing actions, and nobody checks how transfer expenditure interacts with squad rotation. We live in an era when world football has moved to expected goals, PPDA, and goalkeeper positioning ranges – while here, analysis still stops at... emotion. I call this the 'N/A report syndrome'. Let me explain from the root. Back in 2026, when I dared to criticise Mohamed Salah's lack of efficiency after Liverpool's draw against Burnley, I provided concrete numbers: 8 shots, 1 on target, 0 goals. I was abused as 'a woman who doesn't understand football', but Salah then scored seven goals in four games to prove me wrong in prediction and right in method. Without a data foundation to hold on to, everything I wrote would have been just noise like those amateur commentators. The N/A syndrome not only appears in the media. It has seeped into the very way Vietnamese clubs operate. Many V.League teams sign players based on flashy highlights and agent promises rather than data dossiers on sprint intensity, misplaced pass rate, or actual chance creation. The consequence is a domestic transfer market full of 'money out of the window' deals, as I once said: 'Transfers are never wrong – only the person paying too much is wrong.' Pause the frame, the real game begins. A deep tactical analysis must start by placing context: which squad is under physical strain, which head coach is under fire, which team is sinking at the bottom of the table. Without that context, every statistic becomes meaningless. In the report I mentioned earlier, the section 'Results & Public-Opinion Cycle Analysis' could not be assessed because no fixture dates, competitions, or number of matches were provided. In Vietnamese football, this happens weekly: reporters recount the scoreline without contextualising it against recent form, injury status, or home-and-away factors. Look at a specific V.League moment: a centre-back launches a long ball upfield to an isolated striker while his holding midfielder has just left the pitch with cramp. The commentator only says 'a thoughtless clearance', but if you pause the frame and measure the rhythm of the match, you see it as the consequence of stretched distances over the final twenty minutes. That is why I always say: 'Tactics do not stay on the board – they live in the fear of each player.' The fear of being dispossessed, fear of fouling, fear of being out of position – all can be read from the legs. I don't watch a match, I watch how they collapse. The match does not die when the opponent scores the third goal; it dies around the 65th minute when the defence retreats too deep, leaving a huge hole in midfield like an open mouth. Vietnamese clubs rarely have video analysts to point that out. Our players are not inferior physically, but their ability to read collective movement is too modest. The N/A report likewise gave me no information about which team should make a substitution at minute 60 or switch to a back three. Because it was empty. There is a contrarian angle I must voice: it is easy to assume Vietnamese football is too poor for data science. But that is false. V.League has data from live tracking platforms, has slow-motion replays from multiple cameras, and even a smartphone can collect basic metrics. The issue is not the lack of technology – it is the lack of habit. Club bosses prefer hearing the story 'he dribbles beautifully' over a dry spreadsheet saying 'he completes 38% of his dribbles'. We must break the stereotype that data is a luxury imported from Europe. I was once abused for saying Salah was not number one; now I am waiting for an apology. What I want to send to Vietnamese sports media professionals is this: accept that you can be wrong, but never offer an opinion without attaching a verifiable statistic. The N/A report should have been a lesson, but it is also a mirror reflecting our lazy thinking. Fans are demanding more than exaggerated claims. Fans are reading league tables, not just highlights. A season truly begins when someone dares to say what nobody else will say. So here it is: Vietnamese football does not lack player quality; it lacks a data-analysis platform serious enough to help them break through. If we continue to write and talk like an N/A machine, then even the dream of reaching the World Cup will remain nothing but a myth. So, when will we start? I will not wait for a two-thousand-word report with complete data. I start today, by demanding that every football story comes with numbers. And you – do you dare to ask: what truly decided this match, at which minute, and through which metric?
