Why the World Cup breeds shocks
Every World Cup favourite carries the same structural weakness. Over a league season, quality compounds; over three group games, it barely has time to show. A side can dominate possession, create ten chances and still lose to the one shot that deflects in. Add travel, unfamiliar climates, squads assembled for a few weeks and the weight of national expectation, and the conditions for an upset are built into the format.
The six case files below span seven decades, and the pattern is consistent. The favourite was rarely outplayed for ninety minutes. More often it dominated, wasted chances, and then met an opponent who had planned specifically for that scenario. The notable exception is 1954, when West Germany were simply better on the day that mattered.
Our underdog ratings weigh the gap before kick-off, not the drama afterwards. Uruguay in 1950 were a serious side, so the Maracanazo scores lower than its legend suggests. North Korea in 1966 were an unknown quantity even to their own group opponents, so they score near the top.
