Mourinho, Real Madrid and the LaLiga Marathon: How Do You Measure Collective Strength?

The rainy night in Guangzhou, I sat in front of the wall of data plastered across my rented room. Three years earlier, I had been a midfielder in the 2026 cohort at the Guangzhou R&F academy, until a knee injury forced me off the pitch. Since then I had taken up a different profession: excavation. Not of earth and stone, but of the numbers buried beneath the surface of a football match. And when José Mourinho stepped in front of the cameras before the Madrid derby against Atlético de Madrid, saying that Real Madrid, beyond the quality of its squad, possessed a strength of enormous meaning to him — the strength of a group — that familiar feeling returned. The whole football world quoted the line. Fans shared it. A wave of optimism spread across forums. As for me, I reopened my old notebook. Data does not lie, but crowds do. He added one more sentence, the one I consider the most noteworthy of the entire press conference: the championship is a marathon, it is not always a highway without any kind of obstacle, but Real Madrid will be there. It sounds beautiful. It sounds reassuring. But within such a long sentence, how many numbers are there? Not a single one. That is why I decided to sit down and write this piece. Not to refute Mourinho — he is one of the greatest strategists of his generation, and I respect him. But to answer a question the crowd skips over: when someone speaks of "collective strength," with what ruler do we measure it? The context of this story matters more than its surface. LaLiga is a league where endurance is worth nearly as much as raw talent. Unlike the European cups, where one great match can change an entire season, LaLiga is a chain of thirty-eight matches stretched across nearly ten months, through cold winters, through international breaks, through injury spells, through weeks when a club must play three matches in seven days. There, the champion is not the team that plays best on a single night. The champion is the team that collapses the least. Mourinho understands this better than anyone. He won LaLiga with Real Madrid in the 2026-2026 season, when his side collected 100 points — a record at the time — and scored 121 goals. But what made that season was not only the goals. It was the ability to sustain form across every matchday, to rotate the squad sensibly, to keep a cool head at the moments when every other club was trembling. When Mourinho spoke of "the strength of a group" before the Madrid derby, he was speaking from his own experience of excavation. But here I must separate two things. One is what Mourinho believes. The other is what the data proves. The belief of a man who has won titles has referential value. But reference is not evidence. I do not watch the match, I excavate it. And when I dig down to the layer beneath that sentence, I find I need to redefine the concept of "collective strength" into something measurable. There are five indicators, in my view, that make up a team's true collective strength in a long-distance race. The first is squad depth — not the number of players, but the number of players who can replace one another without collapsing the quality. A team with fifteen high-class players and fifteen rarely used substitutes will shatter in February. A team with twenty-three players of whom eighteen can start without anyone noticing the difference is a team with depth. The second is the variance of points across each stretch. The champion does not necessarily win the most in one stretch, but must have the fewest runs of dropped points. I once built a database of around one thousand two hundred young players across five top European leagues between 2026 and 2026, cross-referencing minutes played against development curves. The result revealed something few notice: teams with genuine depth tend to have very even points distributions, without long slumps. They do not explode. They sustain. The third is the structure of goal and chance burden. When a team depends too heavily on one individual, that team's xG will fluctuate sharply with that individual's form. A strong collective is one where goals come from many sources, from many positions, from many lines. That is why I always look at the distribution of goals by position before concluding anything about a team's collective strength. The fourth is the capacity to rotate. This is tied tightly to depth, but differs in that it speaks to the determination and competence of the coaching staff. A team with good depth that dares not rotate has depth only as a number. A team that rotates well with poor depth will pay the price at season's end. True collective strength appears when these two factors meet. The fifth, and the point I want to stress most, is the supply of personnel from the academy. Every contract is a geological layer. When you dig down into a successful team, you find beneath it either a youth development system or a scouting network working in silence. The Real Madrid of recent seasons is a prime example: alongside expensive signings, they have maintained a flow of players from the academy and from young transfers brought in early. It is that flow, not the glamorous names, that builds the depth allowing them to survive long seasons. I once wrote, in an eight-thousand-word analysis of Kylian Mbappé after an all-nighter in Guangzhou in 2026, that Mbappé did not appear in a single night, he was excavated across many nights. I recorded every touch he made in the Monaco win over Dortmund, cross-referenced xG and distance covered, then held the draft for three days to verify the numbers before publishing. That principle still holds for a collective: no collective grows strong in a single night. Collective strength is the result of a system running relentlessly across multiple seasons. Looking at Real Madrid today, what do we see? A squad with individual quality at the highest level in Europe. A midfield capable of controlling tempo and transitions. An attack with multiple options. And, more importantly, a core that has played together long enough to understand one another without words. That is the foundation of collective strength. But a foundation is not a result. A foundation is a necessary condition. The sufficient condition lies in the capacity to endure through dense stretches of matches. I always check the number of matches a team must play between December and February — the period when every club is most fragile. A team forced to play twelve matches in six weeks, through long travel, across two fronts, through tense derbies, will reveal its true nature. Not its nature on paper, but its nature in the blood. And this is where the story becomes interesting. The crowd reads Mourinho's sentence as a positive sign. They see a man who has won titles expressing trust in the club, and that is enough. But I read that sentence differently. The crowd looks toward the lights; I look down at the soil beneath. The question I pose is not whether Mourinho is right. The question is: why would a strategist as sharp as he is choose to speak of "collective strength" instead of concrete tactical solutions? When a coach or a former coach is asked about title chances, convention suggests he would speak about squad structure, about how pressing is deployed, about how to exploit gaps between the lines. But Mourinho did not. He spoke of a marathon, of obstacles, of the strength of a group. That is not the language of tactics. That is the language of psychology. And when a man of Mourinho's stature abandons tactical language for psychological language, it is a signal that must be read carefully. It may mean he sees something the data does not say: that this team lacks not talent but stability. It may mean he is trying to shield the players from media pressure. Or it may mean he is saying something he does not entirely believe, because his role in the media allows — and sometimes demands — symbolic statements. I lean toward the third reading. Throughout his career, Mourinho has been famous for using statements to shape public opinion, to build a shield for his players, to place pressure on rivals or referees. A sentence like "we will be there until the end" carries two edges. If Real Madrid win the title, he is the man who saw it first. If Real Madrid fail, that sentence becomes a betrayed promise, and the pressure will weigh on the club — but not on him. This is the point I want to call "the paradox of trust without data." When a team is praised for unquantifiable qualities such as spirit, resilience, or collective strength, that trust does not help the team resist an injury wave. It does not help the team score in the ninetieth minute. It only soothes the fans' anxiety while reality may still be shaking. The history of the Spanish top flight is full of examples of teams praised for magnificent "collective strength" that later collapsed for very concrete reasons: an injury in a key position, a brutal fixture run, an imbalance in the dressing room. I am not saying Real Madrid will follow that path. I am saying trust is not insurance. And an honest observer must distinguish between trust and evidence. I understand why fans want to believe. Football is not only numbers. If football were only numbers, no one would cry when their team loses, no one would stand in the stands in the rain for ninety minutes. Emotion is part of the game. But emotion is not permitted to replace analysis. That is the line a professional observer like me must hold for years. I once cited World Cup 2026 qualifying data to argue before the tournament that France would abandon possession and win through counter-attacks. I was eighteen then, and netizens mocked me, because France kept winning narrowly and did not look like champions. I put forward the numbers: France held only about forty-one percent possession but averaged two point one xG per match. When France beat Croatia four-two in the final, my article was shared more than two thousand times. That was the greatest lesson of my life about going against the crowd with data: not to appear clever, but to see more clearly what is happening. With the Real Madrid story this time, I work the same way. I do not need to know what Mourinho thinks. I need to know what will decide the race. And what decides the race, in a league as long as LaLiga, is the number of dropped points in difficult periods, the number of top-class players who can replace one another, the ability to distribute the goal burden, and the mental endurance of the whole collective when everything goes wrong. Those four factors — none of them can be created by a beautiful sentence. There is one more thing I always pay attention to when watching matches: the silence of the collective after conceding. A team with genuine collective strength will react in a different way from a team with only talent. I have recorded this detail in many matches, and the results are not random. Teams that fall behind yet keep their structure, keep contesting every ball in midfield, keep the distance between their lines, tend to have a markedly higher tendency to turn the game around. That is behavioural data, not technical data, and it does not appear on the scoreboard. But it exists. Other teams, when they fall behind, shatter into separate pieces. The defence pushes up without control, the midfield forgets its defensive duties, the attack seeks hopeless individual balls. That is when individual talent cannot save the collective, because that collective never truly existed as a structure. It was only an assembly. I believe this is precisely what Mourinho meant when he stressed "the strength of a group." But he said it as a man who has created such collectives, not as a man proving that such a collective already exists at Real Madrid today. And that is the difference between a belief and a claim. In football analysis, we have a concept called "the lag of evidence." When a team plays well, people praise immediately. When a team plays poorly, people criticise immediately. But the real evidence of a team's nature only appears after several seasons, when we cross-reference their behaviour across many circumstances. That is why I never conclude about a young player after only a few matches, and never conclude about a collective after a single statement. Back to the story at hand. Real Madrid enter the derby against Atlético de Madrid with many matchdays still ahead in LaLiga. Mourinho insists this club will stay in the race to the end. What interests me is not whether he is right, but what will make that true. And when I look at the club's current structure, I see positive signs and warning signs side by side. Positive, because this team has a midfield deep enough to rotate across multiple competitions. Positive, because they have young players capable of playing in several positions, which a marathon demands. Warning, because a marathon shows no mercy for structural weaknesses. A gap at left-back, a shortage in the centre-forward role, an uneasy relationship in the dressing room — all of these will be magnified many times over across thirty-eight matchdays. Every contract is a geological layer. And so is every season. When we look back at a completed season, we see the sediment: the layer of September when everything was buoyant, the layer of December when everything became harsh, the layer of March when everything had revealed its true nature. The champion is the team that can travel through all those layers without being crushed. So is Real Madrid that collective? I cannot answer that with a single yes or no. What I can do is set out the conditions that must be met, and let the season answer. If this team maintains its structure through the dense stretch from December to February, if they distribute the goal burden evenly enough not to depend on one individual, if they keep dropped points low during difficult moments — then Mourinho's sentence will be proven by results, not by inspiration. That is the real test. And it has not yet begun. What worries me most here is not the possibility of Real Madrid failing. What worries me is how the crowd is receiving this story. When the media turns an optimistic sentence into evidence of strength, they create an expectation disproportionate to the data. That expectation can transform into pressure, and that pressure can affect the psychology of the whole collective — the very collective that is being praised. That is the final paradox of this story. Trust without data can create pressure on the very thing it wants to protect. And a truly strong collective is one that can live with pressure without falling apart. Tonight, I sit again in front of my data board. I will record this sentence of Mourinho's in a separate column, the column of "statements awaiting verification." When the season ends, I will return, cross-reference, and see whether that trust turned into numbers. I do not guess, I excavate. Because the pitch falls silent, memory keeps running, and every sentence from a man who once stood at the peak leaves a geological layer waiting to be dug down into. The crowd looks toward the lights; I look down at the soil beneath. When the pitch falls silent, memory begins to dig. And what I found beneath the dust of time this time is a familiar warning: teams praised for unquantifiable qualities are often the teams we know least about in terms of their true nature. Talent arrives unexpectedly, but collective strength does not. Collective strength is built day by day, through every training session, through every boring match, through every rotation no one mentions on television. It is the kind of strength that only time and data can prove. And precisely for that reason, it deserves to be followed more closely than any sentence.
