On July 1, Senegal were two goals up on Belgium in Seattle. DR Congo had just taken the lead against England, in their first ever World Cup knockout match. By evening, both were out — Senegal fell 3-2 in extra time; DR Congo were undone 2-1 by a late Harry Kane double. Within hours, the same word was doing the rounds: mentality. A comfortable story. It also isn't true — and exactly 36 years ago to the day, football already proved it wrong. Neither team lost because they lacked heart. Senegal built a 2-0 lead through two outstanding goals from Habib Diarra and Ismaïla Sarr. DR Congo took the lead against a title favourite. What turned both matches was specific, not magic. Belgium's comeback started when they sent on Romelu Lukaku at half-time — he scored the goal that dragged them back in. Senegal had no equivalent card left to play. The problem was never courage. It was who was left on the bench when it mattered. The story is older than either team. On July 1, 1990, in Naples, Cameroon led England 2-1 with eight minutes to go in the World Cup quarter-final. Gary Lineker won a penalty and scored. In extra time, he won another. England won 3-2. What the world remembered was not the collapse — it was Roger Milla, 38, pulled out of retirement, dancing around the corner flag after every goal. That image became the story of African football: joyful, instinctive, magical. What got left out was the boring part. Cameroon's coach, Valery Nepomnyashchy, had been sent from Russia in 1988 to train youth teams — he only got the senior job because the previous coach quit after he landed, and worked through an interpreter. Before the tournament, the squad lost every warm-up match, and it took a direct order from President Paul Biya to force the aging Milla into the squad over his objections. What people kept was the dance. Because the magic story was the one everyone repeated, nobody outside the federation felt pressure to fix what was underneath it. Four years later, the cracks became public — the squad tangled in disputes over unpaid money, out in the group stage without a win. The lesson was sitting right there in 1990. It just wasn't the lesson anyone chose to tell. That's the pattern worth naming: when a good result gets explained as spirit, nobody has to explain the system. A federation that hears our boys have heart never hears our federation has gaps. So, the gaps stay open, tournament after tournament, while pundits reach for the same tired word every four years. Senegal's core — Sadio Mané, Kalidou Koulibaly, Idrissa Gana Gueye, Édouard Mendy — are all in their mid-thirties. That's a succession problem: bring the next generation in while the current one still has legs, not after it's gone. Senegal knows this — 18-year-old Ibrahim Mbaye and teenager Bara Sapoko Ndiaye both got minutes against Belgium — but it has to become policy, not emergency substitution. DR Congo's story is related. Twenty-one of their twenty-six players, including Aaron Wan-Bissaka and Axel Tuanzebe, grew up outside the country. Getting that talent onto a plane is not the hard part. The hard part is what happens once they land: whether the camp runs like clockwork, not just when it's televised. This is exactly the moment for Amavubi to pay attention — not as spectators, as students. Rwanda has not yet reached a World Cup. That's an advantage: the lesson is available before the mistake gets made. In 2023, Kigali hosted the first elective FIFA Congress on African soil, and Kigali Pelé Stadium was unveiled the same week. That's the easy part. The hard part, the part nobody photographs, is the machinery behind it: scouting that runs all year, and a pipeline built years before the team needs it. Add an administration stable enough that one rough cycle doesn't undo five years of quiet work, and you outlast any golden generation. Every four years, the world calls it heart. It almost never is. What decides these games is what a federation built, and when it built it. The writer is a professional engineer specializing in process design.
