Some famous teenagers have had their breakthrough moment at the World Cup, including Pelé, who became one of football's all-time greats.
Pelé was 17 when he helped lead Brazil to the World Cup title in 1958. Kylian Mbappé was 19 when he cemented his superstar credentials by leading France to the World Cup title in 2018. Two decades earlier, England's Michael Owen had a coming-of-age moment as an 18-year-old at the 1998 World Cup in France.
The 2026 tournament will feature 22 teenagers, according to the official rosters of the 48 teams published by FIFA.
A few of them have already established themselves with top European clubs, including 18-year-old Lamine Yamal and 19-year-old Pau Cubarsí, the Spaniards who have been thriving with Barcelona for some time. Germany's 18-year-old Lennart Karl just had his breakthrough season with Bayern Munich.
Other already established players are older than 19 but are set to make their first World Cup appearances, including 20-year-old Warren Zaïre-Emery and 21-year-old Désiré Doué, the France internationals who have been regulars with two-time defending Champions League winner Paris Saint-Germain.
Other 21-year-olds who have been around for some time but will possibly debut at the tournament include England's Nico O’Reilly of Manchester City and Türkiye's Arda Güler of Real Madrid. Nico Paz, another 21-year-old, made Argentina’s World Cup squad after thriving with Como in the Italian league, helping the club qualify for the Champions League for the first time.
Here’s a look at five up-and-coming teenagers who could have breakthrough performances during soccer’s showcase event:
Gilberto Mora
One of Mexico’s most promising prospects in years, Mora could become the youngest Mexican player to appear in a World Cup at age 17. He is the youngest player among the rosters of the 48 teams playing at the tournament this year.
The midfielder has been making waves in Liga MX with Tijuana. He started for the Mexico team that won the Gold Cup in 2025.
In August 2024, he was the youngest to start and score in the Mexican first division at age 15. In January 2025, he was the youngest to debut for Mexico at 16.
Some of the top clubs reportedly scouting the teenager include Real Madrid, Barcelona and some Premier League teams.
Yan Diomande
The 19-year-old winger will star for Ivory Coast at the World Cup after impressing with Leipzig in the German league.
He moved to the United States at a young age and excelled while playing high school soccer in Florida. Diomande had trials with Major League Soccer teams Colorado and Charlotte but ended up moving to Spanish club Leganes in 2024.
It wasn’t long before Leipzig signed the promising star last year. He also debuted for the national team last year, featuring in the Africa Cup of Nations.
Endrick
The 19-year-old striker will have a chance to shine with Brazil after finishing the season well with Lyon in the French league.
Endrick thrived with Brazilian club Palmeiras before moving to Real Madrid as the next top prospect from Brazil. He had a rough start with the Spanish powerhouse and was sent on loan to Lyon, where he thrived this last season.
It was enough for new Brazil coach Carlo Ancelotti to include him on the World Cup squad, where he will compete with the likes of Neymar, Vinícius Júnior, Raphinha and another up-and-coming teenager in 19-year-old Rayan, who impressed with Bournemouth in his first Premier League season.
Ibrahim Mbaye
The 18-year-old Mbaye became the youngest Senegalese goal scorer in the Africa Cup of Nations earlier this year, helping Senegal reach the final. He was 17 at the time.
The forward was a member of PSG’s academy and made his French league debut as a 16-year-old in 2024.
He made his Champions League debut last year and progressively got more playing time with PSG this season, including in the top European club competition won by the French club.
Kendry Páez
The 19-year-old attacking midfielder has been a regular with Ecuador.
Chelsea struck a deal in 2023 to sign Páez from Ecuadorean club Independiente del Valle when he turned 18 in 2025. Chelsea loaned him to French club Strasbourg last year, and he is currently playing on loan with Argentine powerhouse River Plate.
A strong World Cup is likely to bring Paéz, who is known for his nifty dribbling and explosive changes of pace, back to Europe.
