Every World Cup hands a few unknowns their moment, and the biggest tournament in history has been no different.

Across three weeks and 48 teams, a clutch of young players have sent their stock soaring, some with a goal that travelled around the world, others with the quieter, harder-to-fake evidence of the underlying numbers.

A group-stage sample is a small one, of course: two or three games is not a career. So rather than lean on a single highlight, we have used data from Opta and Wyscout, to pick out the five biggest risers.

Here they are, ranked by the noise they have made. Look out for these guys in the knockout rounds

Five biggest risers in World Cup 2026 group stage

Johan Manzambi (Switzerland, 20)

Switzerland walked out of the group stage as winners of Group B, and a 20-year-old who started the tournament on the bench is a large part of why. Johan Manzambi came on against Bosnia-Herzegovina and scored twice in a 4-1 win,

That made him the youngest Swiss player ever to score a brace at a World Cup, at 20 years and 247 days, and the only one to do it as a substitute. Then, in the decisive group game against Canada, he added a goal and an assist to send his country through as section winners.

None of it is a fluke. Across his three group games, just 146 minutes and most of them off the bench, Wyscout credits Manzambi with three goals from a combined expected-goals value of under 1.0, the sign of a ruthless finisher, alongside 4.3 dribbles per 90.

It tracks with a breakout club season: 16 goal involvements in 47 appearances in his first full Bundesliga campaign at Freiburg. He drifts inside off the left, arrives late in the box and finishes with a coolness that belies his age. Switzerland boss Murat Yakin surely cannot keep him out of the starting XI much longer. 

Yan Diomande (Ivory Coast, 19)

If you do not follow the Bundesliga, the World Cup was your introduction to Yan Diomande, and what an introduction. The Ivory Coast winger was named man of the match on his tournament debut against Ecuador, creating five chances, the most by any player on the opening matchday, while winning 11 of his duels. At 19 years and 212 days, he became the youngest player ever to represent the Ivory Coast at a World Cup.

Wider tournament data back up the eye test. Across his three group stage appearances, Wyscout has Diomande at 7.4 dribbles per 90 at a 75% success rate and winning 63.6% of his duels, figures most senior wingers would take, never mind a 19-year-old.

Against Ecuador he completed seven of his eight attempted dribbles. Club form underwrites all of it: named the Bundesliga’s Rookie of the Season at RB Leipzig after 12 goals and eight assists, he trailed only Lamine Yamal for goal involvements among teenagers in Europe’s big-five leagues, and ranked third for completed dribbles overal behind Lamine and Vinicius Junior. 

Ibrahim Mbaye (Senegal, 18)

Some players ease their way onto the big stage. Ibrahim Mbaye announced himself with a thunderbolt. The 18-year-old came off the flank against France in Senegal’s opener and fired in from a tight angle to become the youngest player ever to score for an African nation at a World Cup, at 18 years and 142 days.

It was his only shot on target of the group stage, and he buried it. The wider Wyscout picture is of a teenager utterly unfazed by the stage: a flawless 18 passes from 18 against Norway, 6.3 dribbles per 90 and 63.6% of his duels won across the two games.

A Paris Saint-Germain academy product comfortable on either flank, Mbaye plays with a directness that belies his years, happy to take defenders on and back himself one-against-one. He offers Senegal a different kind of threat to established names such as Sadio Mane. 

Ayyoub Bouaddi (Morocco, 18)

Not every breakout star scores the goals. Ayyoub Bouaddi is the one in this list who does the work that lets the others shine, an 18-year-old holding midfielder who has played the tournament with a composure that has drawn admiring glances from neutrals.

And he did it against the very best. As per Wyscout, Bouaddi completed 55 passes per 90 at 91.3% accuracy through the group stage while winning 61.1% of his duels. Against Brazil, he completed 92% of his passes and came out on top in 12 of 20 duels as a teenager screening the Morocco back four. It is no surprise.

In Ligue 1 this season, only 10 midfielders to contest 100 or more duels bettered his 55.6% success rate, and he was younger than every one of them. Born in France, Bouaddi switched his allegiance to Morocco in May. His nation progressed the the Round of 16 with a penalty shootout win over the Netherlands.

Pau Cubarsi (Spain, 18)

Not every World Cup breakout is loud. Pau Cubarsí has spent the group stage doing something quietly remarkable, anchoring the defence of a tournament favourite at just 18, and barely giving the ball away. The Barcelona centre-back stepped into Spain’s back line as if he had been there a decade, bringing the same unflappable composure that long ago made him a fixture at the Camp Nou.

The Wyscout numbers are startling for a defender. Cubarsi is averaging 92 passes per 90 at 97.6% accuracy across the group stage, and against Cape Verde, he completed 101 of his 103 passes, while winning two-thirds of his duels and two-thirds of his aerials. Factor in that 94.7% of all his attempted actions came off, and you have a teenager dictating matches from the back against senior international forwards. 

The one to watch

If you are picking just one to follow into the knockouts, make it Johan Manzambi. He has the goals, the platform of a Switzerland side good enough to go on a run, and the look of a player about to graduate from super-sub to certain starter. The group stage made the world take note of these five names. The next fortnight will decide which of them the tournament remembers.
