Qatar 2022: the only World Cup host to lose every game.
Usually, hosting is a huge advantage: host nations win 62% of their games at their home World Cup, and 49% at other World Cups.
Six hosts went all the way: Uruguay, Italy, England, West Germany, Argentina and France, the last in 1998.
In 2026 there were three hosts. Mexico won their first four games. None of the three reached the quarter-finals.
Home advantage opens the door. It doesn't carry you through it.
