'Although fewer than 3,000 attended the Hungary/Wales World Cup match in 1958, FIFA insists that 20,000 were there.'
The discrepancy between the two figures arises as a consequence of the Cold War. At the 1958 World Cup in Sweden, spectators actively boycotted a playoff match between Hungary and Wales to show their support for Imre Nagy, Hungary's former Prime Minister, who had been executed the previous day in the wake of the 1956 invasion of Hungary by the Soviet Union. Actual attendance totaled just over 2,800, but FIFA still claims the number is 20,000.
