Pau Cubarsí and Lamine Yamal: Spain's Teenage Stars Shine at World Cup

Luis de la Fuente insisted last summer that Pau Cubarsí’s absence from Euro 2024 had nothing to do with age. He said he simply had four centre-backs he trusted more at that moment.

That hierarchy has been ripped up in less than a year.

In North America, there are few – if any – defenders operating at a higher level than the 19-year-old. Spain’s perfect defensive record at this World Cup belongs to the collective, but the calm figure at the heart of it all keeps drawing the eye.

This is not just about one prodigy, of course.

Mikel Oyarzabal sets the tone with his pressing from the front. Rodri, once again, patrols midfield like it belongs to him, snuffing out danger before it ever reaches the back line. Behind them, every member of the defensive unit has hit stride:

• Marc Cucurella is playing like a €60 million full-back, underlining why Real Madrid were prepared to prise him from Chelsea.
• Unai Simón has rewarded De la Fuente’s faith, five straight clean sheets justifying his place ahead of David Raya and Joan García.
• Aymeric Laporte, at 32, looks as assured as at any point in his career.
• Pedro Porro, so often erratic for Tottenham, suddenly resembles a model of reliability in a Spain shirt.

The structure is solid. The numbers are flawless.

Yet Cubarsí is the piece that changes the feel of the whole picture.

A teenager who looks born for the stage

Perhaps nobody should be shocked that he looks this comfortable. Cubarsí has been a fixture at Barcelona since 17, a La Masia product groomed for exactly this kind of responsibility. Xavi labelled him “an era-defining player” at club level; Carles Puyol went further, predicting he would be Barça’s first-choice centre-back for the next 15 years.

Those are heavy words. Cubarsí treats them like they weigh nothing.

He has said he doesn’t feel pressure on the pitch, and his World Cup displays back that up. At 19, on the sport’s grandest stage, he has barely put a foot wrong. Positioning, timing, decision-making under stress – all of it belongs to a veteran’s repertoire.

Laporte’s presence beside him matters. De la Fuente has openly highlighted how the former Manchester City defender steadies his young partner, and the chemistry between them is obvious. One talks, one scans, both step in unison. The result is the “phenomenal balance” the coach wanted at the heart of his defence.

Yet Cubarsí brings something extra.

He isn’t just a stopper; he’s another playmaker. A centre-back who treats the first line of build-up as his canvas. Schooled at La Masia, he breaks pressure with the same ease others clear their lines. At the time of writing, only Rodri has completed more passes for Spain at this World Cup. That statistic tells its own story: Spain don’t just trust him to defend their box, they trust him to start almost everything.

No wonder he is one of only four players in the squad to have played every single minute of the campaign so far. De la Fuente has built his structure around Rodri in midfield and Cubarsí behind him. The teenager has gone from “not quite ready” to “undroppable” in the space of a tournament cycle.

Yamal searching for his spark

Up the pitch, the other teenage phenomenon in this Spain side has taken a different road.

Lamine Yamal arrived at this World Cup under a cloud of uncertainty. A hamstring injury had cut short his 2025-26 season with Barcelona and threatened to rule him out of the tournament altogether. He missed both warm-up games. When he finally appeared, it was for just 19 minutes in a goalless, jarring draw with Cape Verde.

Then came the reminder of what he can do.

Yamal started against Saudi Arabia in Atlanta, played only the first half of a 4-0 rout, and transformed Spain’s attack in those 45 minutes. He opened the scoring and changed the geometry of the game, stretching the pitch, demanding double-teams, forcing defenders to turn and chase.

That felt like the ignition point. It hasn’t quite worked out that way.

He flashed his dribbling brilliance in the round-of-32 demolition of Austria, a match that entered the record books as Spain became the first team since Pelé’s Brazil in 1958 to start two teenagers in a World Cup knockout game. History on the teamsheet, swagger on the ball.

Yet the contest with Nuno Mendes continues to nag at him. In the tight 1-0 win over Portugal, the Paris Saint-Germain full-back again managed to blunt Yamal’s threat, keeping him away from the decisive moments in the final third.

The numbers underline the frustration.

The most feared winger in world football is still chasing his first assist of this World Cup heading into Friday’s quarter-final against Belgium. Just five chances created so far. For a player who lives on end product, that tally feels out of character.

Yamal knows it. And he doesn’t hide from it.

“I’m very demanding of myself,” he told Mundo Deportivo. “I’m never satisfied with what I’m doing. Besides that, I just need to keep playing. I was out for almost two months, and it’s not the same as when you’ve already played seven games in a row.

“Keep touching the ball, keep playing, keep adding minutes and, obviously, that [big] match will come. In the end, people remember these moments, from the round of 16 and the quarter-finals onwards. That’s when I’m most motivated.

“I’ve taken this whole process calmly so I can arrive at this point in good shape. I feel great, eager to show what we are as Spain and what I am.

“I’ve never been the best player in the group stage. The closer the important matches get, the semi-finals or the final, the better I play.”

That is not the language of a teenager daunted by the stage. It is the mindset of a player who believes the tournament bends towards its decisive nights – and that his game rises with them.

A terrifying prospect for the rest

Spain have already seen this film once. At Euro 2024, Yamal grew into the competition and delivered when the tension peaked, helping drag La Roja over the line when the margins shrank and the pressure spiked.

Now, as the World Cup moves into its sharpest phase, the idea of a fully firing Yamal arriving just as Cubarsí cements himself as an “era-defining” presence at the back is a chilling prospect for Belgium and everyone else still standing.

Spain came to North America with a new generation and a few questions.

They approach the quarter-finals with a defence that hasn’t been breached, a 19-year-old centre-back dictating games from deep, and an 18-year-old winger convinced his moment is only just around the corner.

If the past few weeks have belonged to Cubarsí, the coming ones may yet belong to Yamal – and then the rest of the world will have to ask how long anyone can realistically keep this Spain side at bay.
