Every World Cup creates new heroes, unexpected stories and teams that exceed all expectations. While traditional giants such as Brazil, Argentina, France, England and Spain will dominate the headlines heading into FIFA World Cup 2026, history tells us that at least one outsider will make a deep run.
With the tournament expanding to 48 teams for the first time, there is even greater potential for surprises. More nations, more matches and new pathways through the knockout rounds could create the perfect conditions for a dark horse to emerge.
What Is a “Dark Horse”?
The term “dark horse” dates back to 1831 and was first popularized by British statesman and novelist Benjamin Disraeli in his novel The Young Duke. In one of the book’s horse-racing scenes, an unknown horse unexpectedly storms past the favorites to win. Disraeli famously described it as:
"A dark horse, which had never been thought of… rushed past the grandstand in sweeping triumph.”
The horse itself was fictional, but the phrase quickly entered the horse-racing world to describe a competitor whose abilities were largely unknown to the public. Overtime, it spread into politics, business and sports, where it came to mean an overlooked contender capable of surprising everyone.
The FIFA World Cup has produced its share of dark horses. Croatia reached the final in 2018 despite starting the tournament as outsiders. Morocco became the first African nation to reach a World Cup semifinal in 2022. Costa Rica stunned England, Italy and Uruguay on its way to the quarterfinals in 2014.
The question heading into 2026 is simple: who will be next?
Here are seven teams capable of shocking the football world.
1. Norway
Norway enters the tournament with arguably the strongest squad in its modern history. Led by Erling Haaland and Martin Ødegaard, the Scandinavian nation finally has world-class talent in multiple positions.
What many younger fans may not realize is that Norway has not appeared at a World Cup since 1998. Despite producing stars such as Ole Gunnar Solskjær and JohnArne Riise, the nation repeatedly fell short of qualification over the past two decades.
That drought may finally be ending. Haaland is already one of the most feared goalscorers in world football, while Ødegaard has developed into one of the Premier League’s most creative midfielders. Add emerging talents such as Antonio Nusa and Alexander Sørloth, and Norway suddenly possesses a squad capable of troubling elite opponents.
One intriguing piece of trivia: Norway remains one of the few nations with an all-time winning record against Brazil, having never lost to the five-time world champions in official matches. It’s a reminder that this footballing nation has a habit of punching above its weight.
For a country of just over five million people, a deep World Cup run would be one of the greatest achievements in its football history.
2. Japan
Japan has earned a reputation as one of international football’s most disciplined and technically gifted teams. The Samurai Blue impressed the world at the 2022 World Cup by defeating both Germany and Spain during the group stage.
Their rise has been decades in the making. Since the launch of the J. League in 1993, Japan has invested heavily in youth development, coaching and infrastructure. The result is a generation packed with players thriving in Europe’s top leagues.
Stars such as Takefusa Kubo and Wataru Endo give Japan quality throughout the pitch. More importantly, the team plays with a tactical discipline that often frustrates more talented opponents.
Confidence within the Japanese camp is equally striking. Head coach Hajime Moriyasu has repeatedly stated that his ambition is not simply to reach the knockout rounds but to win the tournament itself. “I have set a very high standard for the team, and that is to become world champions,” he said during qualifying.
Japan has reached the Round of 16 four times but has never advanced further. Many observers believe this may be the strongest Japanese side ever assembled and, perhaps, the one capable of finally breaking into the quarterfinals or beyond.
A fascinating fact for football fans: before launching the professional J. League in 1993, Japan was considered a minor football nation. In just three decades, it has transformed itself into one of the most respected programs in world football through investment, planning and patience.
3. Ecuador
Ecuador may not attract the same attention as South America’s traditional powers, but it continues to develop a formidable side. Young, athletic and defensively solid, Ecuador has proven difficult to beat against elite opposition.
One fascinating aspect of Ecuadorian football is the influence of altitude. Many players develop in Quito, one of the highest capital cities in the world at more than 2,800 meters above sea level. The physical demands of training in such conditions have helped produce generations of remarkably fit and resilient players.
Midfielder Moisés Caicedo has become one of the world’s most complete midfielders, while defender Piero Hincapié provides leadership beyond his years. Ecuador’s squad is among the youngest in the tournament, meaning many of its stars could still be improving when the World Cup begins.
Football observers are beginning to take notice. Several analysts have highlighted Ecuador as one of South America’s most underrated teams, with the nation’s impressive consistency and defensive organization turning heads.
Interestingly, Ecuador has qualified for the World Cup five times despite having a population less than one-third the size of neighboring Brazil. Their rise has been one of South American football’s most impressive success stories.
Its favorable draw could make Ecuador one of the most dangerous outsiders in the competition.
4. Senegal
African teams have long dreamed of producing a World Cup finalist. Senegal has the talent and experience to make that dream a reality.
The country’s footballing reputation was forged in 2002 when Senegal shocked defending champions France in the opening match and reached the quarter finals in its first-ever World Cup appearance. That team became an inspiration across the continent.
Today’s squad is equally impressive. Players such as Nicolas Jackson, Ismaïla Sarr and Kalidou Koulibaly bring experience from Europe’s biggest leagues, while Senegal’s victory at the 2022 Africa Cup of Nations proved they can win under pressure.
Former Senegal star El Hadji Diouf has long argued that an African nation can eventually win the World Cup. While such predictions were once dismissed as wishful thinking, Morocco’s semifinal run in 2022 has made that possibility seem more realistic than ever. Senegal’s current squad may be among the continent’s best opportunities to prove him right.
Few fans realize that Senegal’s famous 2002 victory over France came against a French side featuring many players with Senegalese heritage. The result remains one of the most symbolic upsets in World Cup history.
Few teams combine physicality, speed and defensive organization as effectively as Senegal. They may not enter the tournament among the favorites, but they possess all the ingredients required for a solid run.
5. Colombia
Colombia appears to be rebuilding at exactly the right time. The team combines experienced leaders with an exciting new generation of attacking talent.
Football runs deep in Colombian culture. Streets, beaches and public squares across the country regularly become impromptu football pitches, helping produce generations of technically gifted players.
While many fans remember James Rodríguez’s Golden Boot-winning performances in 2014, today’s team is increasingly built around the explosive pace and creativity of Liverpool star Luis Díaz. Colombia has also become more balanced defensively than some of its previous generations.
Much of Colombia’s hopes will rest on the shoulders of Díaz. He has earned a reputation as one of the most exciting attackers in world football, capable of producing moments of brilliance that can change a match in an instant. In tournament football, where knockout games are often decided by a single moment, that quality is invaluable.
Colombia’s best-ever World Cup finish came in 2014 when they reached the quarterfinals. Many supporters believe the current generation has enough depth to finally surpass that milestone.
The nation has quietly developed into one of South America’s most consistent sides. If Colombia builds momentum during the group stage, it has enough quality to challenge much bigger names in the knockout rounds.
6. Morocco
After reaching the semifinals in Qatar 2022, Morocco can hardly be considered an unknown quantity. Yet many fans still overlook them when discussing potential champions.
That may be a mistake.
Morocco’s remarkable run four years ago was no fluke. The Atlas Lions defeated Belgium, Spain and Portugal while becoming the first African nation ever to reach a World Cup semifinal. Their defensive record was extraordinary, conceding just one goal scored by an opposing player during the entire tournament.
An interesting feature of Morocco’s squad is its global makeup. Many key players were born and developed in Europe before choosing to represent their ancestral homeland. Stars such as Achraf Hakimi, Sofyan Amrabat and Hakim Ziyech have helped create one of the strongest squads in African football history.
The mindset within the Moroccan camp remains one of its greatest strengths.Following the team’s historic run in Qatar, coach Walid Regragui famously asked, “Why shouldn’t we dream of winning the World Cup?”. The quote quickly became a rallying cry not only for Morocco but for underdogs everywhere.
Morocco’s 2022 campaign changed perceptions of African football. For decades, reaching the semifinals was viewed as an impossible barrier. Morocco proved otherwise.
With many of those players still in their prime, Morocco may be capable of another historic run.
7. Mexico
Playing in front of home crowds could provide Mexico with a significant advantage. As one of the tournament’s host nations, they will benefit from familiar conditions and some of the most passionate supporters in world football.
Mexico’s World Cup history is filled with both pride and frustration. Despite regularly qualifying for the tournament, the team has repeatedly fallen in the Round of 16. Mexican fans even have a phrase for the elusive quarterfinal appearance they crave: "el quinto partido” - the fifth match.
History, however, offers reason for optimism. Mexico’s two best World Cup performances came when they hosted the tournament in 1970 and 1986, reaching the quarterfinals on both occasions.
Mexican football icon Hugo Sánchez has often argued that the country’s ambitions should extend far beyond merely reaching the quarterfinals. Hosting the World Cup once again provides a unique opportunity to finally take that next step.
Mexico is also one of only a handful of nations to host three different World Cups. That experience, combined with passionate home support and emerging stars such as Santiago Giménez, could make El Tri a dangerous opponent for anyone.
Final Thoughts for FACT-ory readers …
Every World Cup needs its Cinderella story.
In 2022, Morocco captured the world’s imagination by becoming the first African nation to reach a World Cup semifinal. Their journey was built on defensive resilience, tactical discipline and an unbreakable belief that they could compete with the world’s elite. Victories over Belgium, Spain and Portugal showed that a well-organized team can overcome even the biggest footballing powers.
Before Morocco, there was Costa Rica in 2014. Drawn into a so-called “Group of Death” alongside Italy, England and Uruguay, few gave them any chance of advancing. Yet they topped the group, stunned the football world and reached the quarterfinals, where they were only eliminated on penalties by the Netherlands. Their run remains one of the greatest underdog stories in World Cup history.
Those stories embody what Morocco coach Walid Regragui meant when he asked, “Why shouldn’t we dream of winning the World Cup?” Every dark horse enters the tournament carrying that same belief. Most will fall short. One may rewrite history.
The expanded FIFA World Cup 2026 could deliver an even bigger surprise.
Whether it is Norway’s golden generation, Japan’s technical excellence, Ecuador’s youthful energy, Senegal’s athletic power, Colombia’s resurgence, Morocco’s proven pedigree or Mexico’s home advantage, one of these nations could become the team everyone is talking about.
The question is simple: which dark horse will seize the moment and make history?
