NXGN 2026: Lamine Yamal, Estevao and 10 teenage wonderkids set to light up the 2026 World Cup

Not just the standout teenager at this summer's World Cup, there is a real chance that Lamine Yamal will be the standout player in North America, so talented is the Barcelona and Spain winger. Ever since he marked his international debut with a stunning goal against Georgia as a 16-year-old, Yamal has been an automatic selection for Luis de la Fuente.

He has already shown that he will be daunted by playing at a major tournament, having run riot at Euro 2024 as La Roja triumphed in Germany. Yamal's goal to open the scoring against France in the semi-finals was a thing of real beauty, and his club form since suggests that more of the same could be on the menu as he looks to lift the World Cup just six days after he turns 19 on July 13.

Yamal may not the only teenager in the Spain line-up, though. Pau Cubarsi started four of La Roja's six World Cup qualifiers in late-2025 and looks to be establishing himself in De la Fuente's plans having been a slightly surprising omission from Spain's victorious Euros squad.

The 19-year-old has been a mainstay of Hansi Flick's Barcelona for over two years now, with Cubarsi's composure on the ball and passing ability matching his high-level defensive instincts. There's now a chance he will form one half of what would be a young but very exciting centre-back partnership alongside Real Madrid's Dean Huijsen.

Outside of Yamal, the teenage debutant who most are excited to see in World Cup action is Estevao. The Chelsea winger has produced some moments of magic during his debut season of European football, and that helped him lock down a starting spot in the Brazil team during their games towards the end of 2025.

Estevao scored five goals in his four starts for Carlo Ancelotti's side between September and November, putting him in a strong position amid intense competition for places in the Selecao's attack. He was left out of the squad for March's friendlies due to the niggling injury issues that have plagued him in recent weeks, but the 18-year-old should be fighting fit to make a real impact for the five-time world champions this summer.

Elsewhere in South America, Ecuador midfielder Kendry Paez is one of the most experienced teenagers in terms of international caps set to be on show this summer. Currently playing his club football on loan at River Plate, the Chelsea youngster has been tipped as a potential World Cup star from as far back as 2023, when he made his international debut at 16.

Paez subsequently became the youngest player to ever score in CONMEBOL World Cup qualifying a few weeks later, but he has mostly been used as a substitute at international level since the 2024 Copa America. That is not to say that the 18-year-old won't be able to make a big impression in North America. Indeed, Paez has sufficient magic in his boots to catch the eye for one of the tournament's dark horses.

Perhaps now more than ever before, a number of players are being presented with a choice when it comes to their international allegiances, with plenty of likely participants in the World Cup set to represent countries they may not have envisioned playing for while growing up. Ibrahim Mbaye, for example, spent his childhood lining out for France at every level up to Under-20s, only to accept a call-up from Senegal in November.

The 18-year-old netted on his second appearance for The Lions of Teranga, thus becoming the west African nation's youngest-ever scorer, and then played a role in their run to the Africa Cup of Nations final, where he scored once and assisted twice. The Paris Saint-Germain forward will, thus, be confident of leaving his mark on his second major tournament of 2026.

As co-hosts, Mexico were always going to be under a lot of pressure at the World Cup, even before their failure to get out of the group stage in 2022. El Tri, then, are looking for new heroes to emerge, and the weight of expectation has been placed firmly on Gilberto Mora's shoulders.

The 17-year-old, nicknamed 'The Mexican Pedri', was thrust into his country's line-up for the knockout rounds of the 2025 Gold Cup, and he ended up playing a key role as Javier Aguirre's side claimed the trophy, making Mora the youngest player to win a major international tournament, breaking a record set by Yamal 12 months earlier. Injury has sidelined the Club Tijuana starlet since January, but there is increasing confidence that Mora will return to fitness before Mexico kick-off the tournament on June 11.

Much will be made of Croatia's veterans once again this summer, with 40-year-old Luka Modric leading the way at the fifth World Cup of his illustrious career. But there is a new generation of talent emerging behind those household names, with Luka Vuskovic undoubtedly one of the most exciting following a season where he has emerged as one of the most promising young centre-backs in Europe.

The Tottenham loanee has shone during his time at Hamburg, leading to interest from Barcelona in his services, while he earned his first two international caps during World Cup qualifying. A real threat from set-pieces as well as being a top defender, 19-year-old Vuskovic could even start for Zlatko Dalic's side this summer as Josko Gvardiol faces a race against time to prove his fitness ahead of the big kick-off.

While all of the aforementioned players had international experience under their belts heading into 2026, there are a few youngsters set to be capped for the first time at senior level during this month's window. The most intriguing of these 'bolters' is Lennart Karl, who has enjoyed a superb breakout season for Bayern Munich, for whom he has eight goals and six assists in all competitions despite being in a battle for minutes with Ballon d'Or contenders Michael Olise and Luis Diaz.

The 18-year-old only made his U21s debut in November, but Karl has the capability to make things happen for a Germany team that has been lacking in creativity since the Euros.

Rodrigo Mora already has an international winners' medal to his name as he was a member of the Portugal squad who triumphed at the UEFA Nations League finals in 2025. The Porto playmaker didn't make it off the bench, however, and was overlooked by Roberto Martinez for the remainder of the year.

Having rejected a mega-money move to Saudi Arabia in August, Mora hasn't quite replicated the outrageous form he showed during his breakout season in Portugal, but the 18-year-old attacking midfielder remains one of Europe's brightest talents and has just been brought back into the Portugal fold for this month's friendlies against Mexico and USA, meaning he should have the chance to impress Martinez before the Spaniard names his World Cup squad.

Back in November, Nathan De Cat was playing at the U17 World Cup in Qatar, but now the midfielder has a genuine shot at being involved in the real thing this summer after earning his first senior call-up.

Notionally a defensive midfielder, the Anderlecht ace has taken his game to new levels in recent weeks after being utilised as a No.10, and the likes of Bayern Munich and Borussia Dortmund are now preparing themselves for a summer bid. Of course, his value will only increase if he earns himself a spot in Rudi Garcia's Red Devils squad for the World Cup finals.
