The term dark horse has become slightly corrupted in football. It no longer refers to a true unknown but to a nation outside the elite quietly building toward something significant: a golden generation coming of age, a coaching system clicking into place, a squad carrying more quality than the betting markets acknowledge.
History offers a reliable guide to what that can mean. Cameroon beat Argentina in 1990. Senegal dismantled the defending champions France in 2002. Costa Rica topped a group containing England, Uruguay and Italy in 2014 before taking the Netherlands to penalties in the quarter-finals. South Korea in 2002, reached the last four on home soil by eliminating Portugal, Spain and Germany in succession.
In the 2026 tournament, the favourites are well known. The more intriguing question is: who will emerge from the shadows to challenge them? These are the teams most likely to do so.
Norway
Norway’s return to the World Cup after 28 years is one of the tournament’s great storylines. When they last appeared, in France in 1998, their current head coach Stale Solbakken was a player in the squad. Now he presides over a golden generation that tore through European qualifying, winning eight from eight, scoring 37 goals and conceding just four. No European side scored more.
The spine of this team is formidable. Erling Haaland scored 16 goals in qualifying alone, an almost incomprehensible return that averaged two per match. Martin Odegaard pulls the creative strings from midfield, while Alexander Sorloth offers an aerial threat that complements Haaland’s movement. Julian Ryerson, Oscar Bobb and Sander Berge add further Premier League and Champions League pedigree throughout the squad.
Senegal
The Lions of Teranga qualified unbeaten from their African group, conceding just three goals in ten matches, and they arrive in North America with a squad that blends the experience of Sadio Mane and Kalidou Koulibaly with a younger generation of genuine quality. Nicolas Jackson, Iliman Ndiaye, Lamine Camara and Habib Diarra represent that emerging wave, and coach Pape Thiaw has built a system around defensive organisation and rapid counter-attacking that makes Senegal difficult to break down.
There is additional motivation. Senegal beat hosts Morocco in extra time of the Africa Cup of Nations final earlier this year, only for the result to be voided following a dispute in the closing stages. Having their continental title stripped has galvanised the squad. They will want to make their point on the largest stage of all, and they have the tools to do it.
Ecuador
Under Sebastian Beccacece, Ecuador have constructed something quietly exceptional. In 19 matches, their record reads seven wins, 11 draws and just one defeat, a narrow loss in Brazil at the very start of his tenure. Since that night in September 2024, no team has beaten them.
The foundation is defensive. Moises Caicedo anchors the midfield for Chelsea, Willian Pacho marshals the backline for Paris Saint-Germain, and Piero Hincapie has established himself at Arsenal as one of European football’s most composed young defenders. Goals are harder to come by, with veteran striker Enner Valencia still carrying much of the attacking burden. But with 12 clean sheets and only seven goals conceded under Beccacece, Ecuador are capable of grinding out results against almost anyone.
Colombia
Colombia arrived at the 2014 World Cup in Brazil and produced one of the tournament’s most joyful performances, reaching the quarter-finals with a squad that captivated the world. Now, with James Rodriguez arriving at what may be his final tournament as captain, they carry arguably greater firepower than that beloved vintage. Luis Diaz, having moved to Bayern Munich and delivered 26 goals and 19 assists last season, is one of the most dangerous wingers in the world. Jhon Duran, Juan Fernando Quintero and Luis Suarez offer further variety in attack.
Manager Nestor Lorenzo has built a pressing system underpinned by genuine defensive solidity, and the results speak for themselves. Germany, Spain, Brazil, Uruguay and Argentina have all been beaten since 2023. Colombia reached the Copa America final in 2024 on the back of a 28-match unbeaten run. They enter Group K alongside Portugal, DR Congo and Uzbekistan, and are capable of topping it.
Morocco
Morocco are perhaps the most difficult team in this field to categorise as a dark horse, given that they reached the semi-finals of the last World Cup and eliminated two former winners along the way. But a managerial change in March, when Walid Regragui departed and was replaced by Mohamed Ouahbi, a relatively unknown former under-23 coach, has introduced an element of uncertainty that the oddsmakers have seized upon.
That uncertainty may be overstated. The tactical identity Regragui embedded in this squad over several years is so deeply ingrained that it does not depend on who stands in the dugout. Achraf Hakimi, Youssef En-Nesyri and Hakim Ziyech know their roles inside out. This is a group that has been through a World Cup semi-final together, that has experienced the pressure of eliminating elite opposition and surviving it.
Morocco open Group C against Brazil, which is immediately one of the most compelling fixtures of the group stage.
