5.Jamaica (2.89 million)
The country of reggae, which has a little more than 2,9 million inhabitants, was not very successful in World Cup preliminaries until 1998, when it reached the final tournament in France.It was a tough mission for an inexperienced team who made its debut with 1-3 defeat against Croatia, and then it was crushed by Argentina(5-0), but they managed to save their honor by beating Japan(2-1), a result which allowed them to finish the competition in 22nd place out of 32 participants. It is a win they have to keep in mind because it might be a very long time until they qualify again.
Jamaica is actually the smallest nation to score in and win a FIFA World Cup game — two feats previously held by Northern Ireland since 1958 — when Robbie Earle scored the side’s only goal in a 3–1 defeat against Croatia and then beat Japan 2–1 at the 1998 World Cup
