Kazan, the night of 27 June 2026. In a small beer hall on Baishizhou Street in Shenzhen, every table leaned one way: Germany would beat South Korea, beat them heavily, beat them to save the champions' dignity. I typed a line onto a forum: South Korea have a 37% chance of winning. Nobody stood up to argue. There was only laughter, clinking glasses, and a friend patting my shoulder to remind me that this was the World Cup, not a lottery.

Two hours later, Kim Young-gwon stabbed the ball home at 90+3 and VAR confirmed the goal. Son Heung-min ran the length of the pitch at 90+6 to roll the ball into an empty net. 2-0. Germany went out in the group stage for the first time since 2026. The beer was still unopened, the bet still unplaced, and I had already seen South Korea beat Germany.

Six years on, I still work the same way: read the data first, read the crowd second. But the biggest lesson came from the times I went against the grain and reality hit back hard.

WHY THE CROWD MISREAD GERMANY

The picture before the final round of Group F in 2026 was clear enough. Germany lost 0-1 to Mexico on the opening day, then escaped Sweden thanks to a Toni Kroos free kick at 90+5. To advance, Germany had to beat South Korea and then wait on the other match. South Korea were already out, but they still had one game left to defend their pride.

The trap lay in the words reigning champions. In the crowd's mind, that shirt automatically adds a goal. The betting market that night priced South Korea's chance of winning at around 12%. I put it at 37% and was treated as a man fishing for attention.

The case for 37% rested on a few very concrete points. Germany created very little of real value from open play across their first two matches; most of their danger came from set pieces or shots from outside the box. South Korea under Shin Tae-yong defended in an exceptionally disciplined low block, happy to surrender almost the entire pitch and protect only the penalty area. And most importantly, Germany had to push up. A team that must win is a team that has already left its own back door open.

The beer hall taught me how to read a match; the line-up only distracted me.

BREAKING OPEN THE CRACK IN THE CONSENSUS

Watching the tape again, Germany dominated possession but most of the ball travelled sideways. South Korea dropped into two banks of four, the distance between the lines almost never exceeded fifteen metres, and the central midfielder always plugged the middle. Germany were forced to cross from the flanks. Crossing into a crowded box is a way of handing the ball to your opponent in a very literal sense.

The more interesting part was the counter-attack. South Korea did not need much of the ball to be dangerous; they only needed space behind Germany's back line. That space opened up from the 70th minute onwards, when the opposing midfield could no longer run back in time after each forward surge. This is the point every possession statistic misses, because those numbers measure who owns the ball, not the distance between the lines of the team that does not.

The Kazan shock repeated itself in Qatar four years later in a different shape. Morocco under Walid Regragui reached the semi-finals after keeping four clean sheets in five matches and conceding only once before the last four. Ahead of the quarter-final against Portugal on 10 December 2026, I wrote that their football was sleep-inducing. In the 42nd minute, Yahya Attiyat Allah crossed and Youssef En-Nesyri headed in. Morocco won 1-0 and became the first African team to reach a World Cup semi-final.

I was wrong about the wording but right about the structure. Morocco were not parking the bus; they were teaching modern football the fear of a side with nothing left to lose.

The third case was Lamine Yamal. On 9 July 2026, in the Euro semi-final at the Allianz Arena, I publicly called this player born in 2026 a product of the media machine. Yamal equalised in the 21st minute with a curled shot from outside the box into the far corner, becoming the youngest scorer in European Championship history. Spain won 2-1. I wrote a follow-up admitting I was wrong, and that piece spread faster than the first.

Three matches, three times on the minority side, two correct and one wrong in a way that forced me to rewrite myself. That record is not bad, but it is not as pretty as it looks. Going against the crowd is a skill, and that skill is only worth something when every contrarian call leaves behind a traceable record.

WHERE I COULD BE WRONG

The problem with this job is survivorship bias. I remember Kazan because it was famous, and Morocco because it was beautiful. The times I went contrarian and lost were shared by nobody, including me.

The sample size of a single football match is tiny. For most of a season, the stronger team still wins. Building a brand on outliers means building a house on the crest of a wave, and waves turn.

I have also romanticised low-block defending more than once. When a weak team holds firm, we call it character. When they collapse, we call it being squeezed until there is no way out. Same block, two different stories, depending on the final score. That is why I force myself to reread every old analysis after each major tournament.

A similar trap sits in injury narratives. The phrase load management gets used constantly and sounds very scientific, but most star rest periods line up with the weeks a club tours Asia or America for commercial friendlies. Players are rested exactly when fans have paid to watch them.

The same holds in the transfer market. Signing fees for free agents are scrutinised far less than transfer fees, even though the money leaving the club is not that different. That silence is far cheaper than a hundred-million-euro deal, and that is precisely why it exists.

WHAT I BRING TO THE NEXT ONE

When competitions shut down during the pandemic, I thought my work was over. I moved to livestreams, replayed old matches, and opened the comments so viewers could ask their own questions. The stadiums were empty, but I never ran out of an audience.

The 2026 World Cup with forty-eight teams will produce more Kazan-type matches. My prediction is that the group stage will deliver at least three wins for the underdog, at least one of them by an Asian side. If I am wrong, I will write a piece admitting it, and you will read it.

I only need to open the stats sheet first and the beer second.
