World Cup 2026: Strongest and Weakest Groups According to the Opta Power Rankings | OneFootball

While some of the 2026 FIFA World Cup groups appear wide open and others heavily stacked, assessing true difficulty can be subjective. Thankfully, we have the Opta Power Rankings to help us rank them from strongest to weakest.

The 2026 FIFA World Cup is upon us. Forty-eight teams will battle it out across 12 groups to secure a place in the knockout stage, with 16 teams heading home after playing just three games.

Some groups look less competitive than others, but it can be difficult to determine precisely how tough each group is. Luckily, we have the international Opta Power Rankings to help us gauge the true quality of each group at the World Cup.

By looking at the Opta Power Ratings for all 48 teams – a score from 0-100, with the worst international team in the world having the lowest rating, and the best having the highest – we can fairly judge how strong or weak each group at the 2026 World Cup is.

So, which is the ‘group of death’ at the 2026 World Cup, and which group is deemed the poorest of the 12? Here are the results:

The 2026 World Cup ‘Group of Death’

The strongest group at the 2026 World Cup is Group I, containing France, Senegal, Norway and Iraq, with the average Opta Power Rating of the four teams in that group the highest (81.8).France are ranked as the second-best national team in the world in the international Opta Power Rankings; only Spain (100) have a higher Opta Power Rating than them (98.6).

They are joined in Group I by Senegal (21st) and Norway (25th), meaning this group is the only one at the 2026 World Cup with as many as three teams ranked inside the top 25 of the Opta Power Rankings on the eve of the tournament.

Even Iraq (ranked 62nd) could prove to be a difficult opponent, showing their strength in a 1-1 draw with Spain a week before the tournament begins.

Group K isn’t far behind as the second-toughest group at the 2026 World Cup. It’s the only pool containing two sides inside the top 10 of the Opta Power Rankings: Colombia (6th) and Portugal (9th).

It ranks behind Group I (81.8) based on the average Opta Power Rating (81.0), but if you were to look at the average Opta Power Ranking (26.8) instead, it would be the strongest.

Group D is also worth a mention as the only group with no side outside the top 50. Containing Türkiye (20th), Australia (28th), Paraguay (30th) and co-hosts United States (36th), it’s also the group with the tightest distribution of Opta Power Ratings, with just 6.5 between the best and worst teams in the group.

That potentially makes it the hardest group to call. The Opta supercomputer agrees with that, too, as the projected points total for all four teams in Group D also has the smallest distribution. United States are deemed group favourites, but their average points total across 25,000 simulations (4.6) is just one point more than Australia (3.5), who are deemed the least likely to qualify from the group.

The Weakest Group at the 2026 World Cup

No group at the World Cup is ever going to be too weak, but with 48 nations represented at this tournament – an increase from 32 – there was a lower bar for qualification in certain regions.

Would Haiti or Curaçao have qualified for a 32-team World Cup, or one where co-hosts USA, Mexico and Canada were present for qualification in the CONCACAF region? Who knows.

The fact is, Haiti (92nd) and Curaçao (131st) are the two lowest-ranked nations at the 2026 World Cup, according to the international Opta Power Rankings, so that means their groups have the biggest differential between the quality of the best team and the worst team.In Group C, there is an Opta Power Rating difference of 35.1 between the best team (Brazil – 92.2) and the worst team (Haiti – 57.1), but the gap is even greater in Group E, where Germany (89.6) have a rating 40.1 higher than Curaçao (49.5).

Despite that, the weakest group at the 2026 World Cup is Group B, as the average Opta Power Rating (70.9) and average Opta Power Ranking (52.8) of the four sides are lower than in any other group at the tournament.

This is because Canada (ranked 37th in the Opta Power Rankings) were given a place in Pot 1 of the draw as co-hosts, and they were by far the lowest-ranked top seed.

None of the sides in Group B are ranked among the top 16 men’s international teams in the world by the Opta Power Rankings, with Switzerland (17th) the highest ranked. They are joined by UEFA play-off winners Bosnia-Herzegovina (77th) and AFC play-off winners Qatar (80th).

Group A is also worth considering among the weakest. It is the only pool at the 2026 World Cup that doesn’t contain a national side ranked inside the top 20 in the world by the Opta Power Rankings. Co-hosts Mexico (24th) are the highest-ranked team in Group A, and they are joined by South Korea (32nd), Czechia (40th) and South Africa (64th).
