Nine Dimensions of a Football Analysis: The Writer's Discipline Before Data

In Brisbane, in my working folder, there is a document file I still keep even though it has nothing to read. It is a football analysis built across nine dimensions: full framework, full headings, full sections, but every data field is empty. No team name, no player name, not a single xG figure, not one line of PPDA. Every conclusion line reads only one sentence: insufficient information to assess.

Many would treat that as a failure. What is an analysis without a conclusion for? But thirteen years of writing about football have taught me the opposite. A trustworthy analysis is not the one with the most conclusions, but the one that knows exactly where it is not yet permitted to speak. A good sports writer is not the one who fills every gap, but the one who can tell which gaps should be left open.

I remember that every time I reopen an old recording. Reviewing footage is not a sign of distrust, but a way of respecting the truth. And the truth, in modern football, does not lie in a single number. It lies in nine dimensions layered on top of one another.

Fifteen years ago, football analysis in Vietnam and in Australia had almost only one dimension: retelling the match. Who scored, who assisted, which team won. The good writer was the one who remembered many moments and retold them smoothly. But when event data and positional data became cheap and widespread, the craft changed at its root. A match can now be read through hundreds of thousands of data points per minute, and the writer no longer competes with memory, but with the ability to choose the right dimension to examine.

The nine-dimension framework I use is not anyone's private product. It is the result of a long process: European club analytics departments separated match data from financial data; governing bodies such as UEFA and the Premier League separated financial compliance from sporting results; sports courts separated transfer law from match law. Every time a major case erupts, people add another dimension to the framework.

Take finance. When UEFA introduced Financial Fair Play (FFP), fans understood it as a spending cap. But FFP is in essence a system for measuring the relationship between revenue and cost, and it only works when revenue data is disclosed transparently enough. The Premier League later replaced it with the Profit and Sustainability Rules (PSR), setting a loss cap at a specific figure. At the same time, the transfer market produced a type of transaction that no system fully measures: signing fees for free agents.

That is why I say modern football analysis cannot have only one dimension. A report on a deal can be right on price, right on the player, but wrong on compliance — and that wrong is exactly what is worth writing. The nine-dimension framework was born so that such wrongs are not missed.

The first dimension is tactics and technique. This is the most familiar dimension, but also the most overused. People talk about formations, about pressing, about possession, and forget that each of those concepts must be tied to a metric. The sophistication of a tactical system is not measured by whether the team plays beautifully, but by the consistency between intent and execution. PPDA, the number of passes an opponent is allowed before each defensive action, is a measure of pressing intensity: the lower the figure, the more aggressive the pressing. But low PPDA is not necessarily good. A high-pressing team with a loose back line will be struck in the face. So the tactical dimension must always come with a question about personnel fit: does this system match the players available.

Here I always remind myself of a principle: before pointing a finger at anyone, I ask myself whether I have read the whole contract. The same goes for tactics. Before criticising a player for playing badly, I must ask whether the system is forcing him to do the opposite of his strengths.

The second dimension is club finance and the transfer market. This is the dimension I believe is most underrated in the Vietnamese market. A deal is not just a number. It has a structure: how much is paid up front, how much is performance-based, how much is a signing fee, how much is an agent's commission. And it has a timeline: how long the contract runs, when the release clause activates. A club's four revenue streams — broadcasting, commercial, matchday prize money, and transfers — are often lumped together, but they move very differently. Commercial revenue can spike within a season; broadcasting revenue is locked into multi-year cycles; transfer revenue depends on selling at the right moment.

I once wrote about a case at The Footy Law that I consider the biggest lesson on this dimension. In 2026, when competitions were suspended due to COVID, I read Lionel Messi's contract with Barcelona carefully and realised that the 700 million euro release clause carried a specific validity date. That date, not the 700 million figure, was what decided the deal. An expired clause still says more than an infinite promise. That is how I learned to read transfers legally: build the timeline first, read the number afterwards.

The third dimension is results and the cycle of public opinion. This is the most addictive dimension because it gives the writer the feeling of speaking about the present. But results are the noisiest thing in football. A team can win three matches in a row while its actual play deteriorates. xG, expected goals, was created to separate process from outcome: it estimates the probability that a shot becomes a goal based on position, angle and context. When xG and actual goals diverge over time, that is a signal. But that signal only means something when the sample is large enough. Three matches say nothing; ten matches begin to speak; a whole season speaks very clearly.

On this dimension, I always separate two kinds of pressure. Pressure on a coach usually comes from results. Pressure on the board usually comes from expectation. Pressure on a key player usually comes from public opinion. These three sources are not in sync, and a good writer is one who points out where they diverge.

The fourth dimension is league context and team positioning. A team does not exist alone. It sits in a food chain: title contenders, European spots, mid-table, relegation zone. Its position in that chain determines how it plays far more than the coach's tactics. A mid-table team buys players on entirely different logic from a title contender. A title contender buys to fill a specific position; a mid-table team buys to resell; a relegation team buys to survive.

I like to examine this dimension through three measures: squad value, financial power, and academy output. These three often do not align, and it is precisely the gap that creates opportunity. A team with high academy output but low squad value is a team living on development. A team with high financial power but low academy output is a team buying success. Both can succeed, but their risks are very different.

The fifth dimension is rules and governance compliance. This is the dimension I am most attached to, and also the most overlooked in everyday reporting. People only remember the law when there is a sanction. But the law operates silently in every deal. There are four basic checks any analysis should run: financial fair play compliance, transfer registration rules, pending disciplinary sanctions, and competition eligibility.

It took me three months to understand that the arm does not belong to the offside law. In 2026, after I wrote that a World Cup goal was offside and was rebutted, I sat down with the entire Laws of the Game and reviewed dozens of situations. What I learned was not just a specific clause. What I learned was that the law changes, and the writer must update before every season rather than rely on memory. An old clause never stops speaking — it only stops being correct.

For each compliance question, I build three scenarios: worst case, central case, optimistic case. The worst case is usually the heaviest sanction the law allows; the central case is a settlement; the optimistic case is that nothing happens. Building all three helps the reader understand that the law is not a verdict, but a range of possibilities.

The sixth dimension is management and the dressing room. This is the hardest dimension to verify because public data is scarce. But three things are observable: the owner's level of investment and patience, the quality of transfer decisions, and structural stability. A club that changes coach three times in two seasons is a club with a structural problem, regardless of where it sits in the table. Dressing-room health shows through leadership structure and how generational transition is handled. When a team has too many players of the same age, generational transition arrives as a shock rather than a process.

The seventh dimension is the risk profile. I group risks into six categories: sporting, financial, personnel, rules, public opinion, and systemic. Each risk is rated on three criteria: level, likelihood, and impact. But there is one kind of risk I have learned to put first: input risk. If the input data is insufficient, every conclusion downstream is meaningless, no matter how elegant the analytical framework.

The eighth dimension is media and expectation. Modern football runs on stories. A story can outlive the truth behind it. On this dimension, I always check two things: whether the story has a data foundation, and whether the sample is large enough. Transfer rumours are the same. A rumour is only credible when we know what tier the source is at and what motive the agent has for pushing it out.

The ninth dimension is industry transmission. This is the broadest dimension and the one that explains why a small event at one club spreads across the whole industry. The transmission chain runs from upstream — academies and the talent supply — through the midstream — clubs and competitions — down to downstream — broadcasting, commercial, derivative markets. A decision upstream, for example an academy closing, takes several years to reach downstream. But when it does, the impact is very hard to reverse.

On this dimension I hold a professional belief I have never seen refuted by data. Big clubs' academies are, at bottom, places that stockpile talent rather than places that grant opportunity. Fewer than ten percent of young players genuinely have a path to the first team. The rest are trained to become transfer commodities. That is not evil, but it must be said plainly, because it determines how we read every academy story.

Here I must say what the nine-dimension framework itself cannot say: the more beautiful the framework, the easier it becomes decoration. I have seen analyses with all nine dimensions, all the tables, all the jargon, and not a single conclusion. That is the paradox of the craft: when we have too many dimensions to examine, we easily forget that the purpose of examining is to decide.

The biggest trap is confusing analysis with verdict. Fans want an answer: was that incident a foul, is that deal valid. The writer has a duty to give an answer grounded in the clause, not in a feeling. But there is also a duty to state clearly when the clause is not enough to answer. A mistake is a footnote; only silence is a verdict. A writer who can say "not enough data" is more credible than one who always has a conclusion.

I once fell into the opposite trap. In 2026, I issued a firm conclusion when the data was insufficient. I was wrong, and I publicly corrected it. That correction was read more than the original. It taught me that readers do not forgive the error, but they respect the fix. Humility before data is not weakness; it is a form of courage.

There is one more thing modern analytical frameworks often overlook: emotion. Football does not run on pure data. It runs on memory, on belief, on fear. An analysis with only data and no emotion will be technically correct but humanly useless. Conversely, an analysis with only emotion and no clauses will be attractive but untrustworthy. My craft is to stand between those two extremes and keep both alive.

Back to the empty document file in the Brisbane folder. I keep it not because it is useless, but because it reminds me of one thing. In an industry where everyone wants a conclusion, the one who keeps the discipline of silence at the right moment is the most credible. Fans remember the goal, I remember the clause. But I also remember that there are times when the clause has not yet been written, and at those times, the most honest thing is to say that I do not yet know.

The question I leave for this season is not which team will win the title. The question is: when a nine-dimension analysis still cannot conclude, do we have the courage to publish it as a gap, instead of filling it with speculation?
