The World Cup is all about watching the best of the best. Once every four years, we see the greatest players of each nation pitted against each other in a battle for football's most prestigious prize. But not every team can be as good as the likes of Germany and Brazil.
Inevitably, some lower-ranked teams end up qualifying for the tournament and know that they don't stand much of a chance of making an impact or even winning a single game. Some of these underdogs manage to spring a few surprises and enjoy a couple of decent results, but many go home without earning a single point.
At the 2018 World Cup, we've already seen the likes of Morocco and Saudi Arabia go out with a whimper after losing their opening games without scoring a single goal, and history is filled with examples of low-ranked nations enduring similarly terrible World Cup campaigns.
It's always an honour and an achievement for any player or nation to appear at a World Cup, and at least these teams can say they took part in football's biggest event - but some of them probably wish they'd never even turned up.
