Dark Horses to Watch: The World Cup Nations That Could Pull Off the Biggest Upset This Summer 

The World Cup 2026 group stage is well underway with half of the nations having played their opening match. We can already feel the energy spread all across the world. But a World Cup wouldn’t be the same without a chaotic team to disrupt the tournament. You know the one where a nation arrives, with absolutely no hype, gets politely mentioned and maybe called “well-organized,” but reaches much further than anyone expects.

This is what makes the World Cup special. It is not just a stage for Brazil, Argentina, France, Germany or Spain (the usual heavyweight suspects). It is also about the team with the right system, the right timing, the stars aligned, that will eliminate big players.

And trust us, every World Cup there is a nation that surprises everyone. So, let’s go through the list of the best underdog teams in the World Cup that you should be paying close attention.

Morocco

Honestly, calling Morocco an upset or an underdog team feels strange after 2022. They reached the World Cup semi-finals in Qatar and managed to beat Spain and Portugal along the way, against what pundits predicted. In fact, they became the first African nation to reach that stage.

So, we’re talking about a serious tactical achievement that was mostly built on defensive organization and their iconic full-back play. But can they pull the same thing this time?

Absolutely! They are not arriving as a mystery anymore. Opponents know their achievements and will respect them, and that changes everything. Why? Well, it is much easier to surprise a giant once than to do it again when everyone has spent four years studying why you were a problem.

It’s like in horse racing, where a horse is called an “underdog” until it wins a big race. Then everyone calls the horse a “champion”. As a bettor, you probably already know this, and it is your job to find “underdog” names before they prove their worth.

If you already have that ability, maybe you should join a handicapping tournament on TwinSpires. But more on this link: twinspires.com/tournaments/

The point is that Morocco has a lot to prove this year, and a rock-solid defense isn’t going to be enough. But they have Achraf Hakimi, Yassine Bounou, and their midfield and wide players look dangerous, so they definitely should be on your radar.

Japan

Now let’s move to Japan, which, honestly, are not really an underdog nation anymore. This year, analysts think that they are too good to be called that. After a strong performance against a talented Netherlands team, they look ready to challenge the heavyweights.

This is a team with players across Europe. A team with impressive technical discipline and a recent World Cup history of making famous nations sweat. In 2022, Japan beat Germany and Spain in the group stage, so they proved they can go head-to-head with the big players.

But the main reason Japan are so dangerous is that they play with intelligence and collective speed. Every player is where they are supposed to be, the timing is good, their defense holds a steady shape, and everything looks calculated.

Then we have to talk about Japan’s team depth, which is much wider than people realize. So, even with injury issues, they are still a major threat for other nations.

Ecuador

Ecuador are not the flashiest team on this list. That might be their strength.

They are not here because everyone expects them to score four goals and become the tournament’s fun neutral favorite. They are here because they can defend, compete, run, tackle, and drag more talented teams into matches that feel like hard work from the first minute.

That is a very real upset profile.

Ecuador’s qualification campaign showed their defensive quality. They were difficult to break down in South America, which is not exactly a friendly environment. You do not survive CONMEBOL by being soft; that’s for sure. You have to handle altitude, travel, physical duels, pressure, hostile crowds, and opponents who can turn one loose ball into a disaster.

Their defensive line is strong, with high-level European talent like Willian Pacho and Piero Hincapié. Moisés Caicedo gives them an elite midfield engine. Enner Valencia remains a major tournament figure and a national-team legend. The question is not whether Ecuador can make matches uncomfortable. 

Norway

Lastly, we have Norway. Okay, maybe not an underdog, but still a nation that can shock everyone. Yes, they have Erling Haaland, and everyone expects them to reach a high stage of the tournament, but secretly we all know that they will hit a barrier sooner or later.

But Erling Haaland changes that. However, one person cannot carry the entire nation to high stages in the World Cup. Then we have Martin Ødegaard, who is one of the creative engines and captain of the Norwegian national team.

His vision is incredible, and he has a direct connection with Haaland, making them a scary combo. 

So, yes, Norway is definitely a nation to watch for. After all, they all dressed up as Vikings for their group photo before the World Cup, so they must be serious.

Final Thoughts

These are some of the World Cup nations that can pull off the biggest upset this summer. But of course, the World Cup is wild, and every four years we’re seeing a nation that went under the radar and surprised big nations.

Will one of them win the whole thing? Probably not, but that’s not the question. These teams can definitely eliminate a nation that can win the World Cup, and that changes the entire tournament.
