You already know Yamal, Güler, and João Neves. Here are the seven you haven't heard of. Yet.

The next generation of World Cup breakout stars

Gilberto Mora — Mexico, 17 years old

Value: €10M ($10.9M USD)
Why he matters: Youngest player in the entire tournament. And he's playing in the opening match.

Mora is a left-footed winger with explosive acceleration and dribbling that makes defenders second-guess their career choices. At 16, he won the Gold Cup with Mexico, breaking Yamal's record for youngest player in a continental final. At the U-17 World Cup last October? Three goals, two assists, absolute chaos.

Mexico kicks off the tournament. If Mora delivers, the world will know his name by halftime.

Lennart Karl — Germany, 18 years old

Value: €60M ($65.4M USD)

Bayern Munich's latest academy masterpiece. Less than a year after his first-team debut, Karl has already put up 9 goals and 7 assists in 39 appearances. He's a left-footed attacking midfielder with genuine creativity — the kind of player Germany has been desperate for since Mesut Özil faded.

Nagelsmann personally pushed for his inclusion. When the Bayern manager tells the national team manager "this kid is ready," you listen.

Nico Paz — Argentina, 21 years old

Value: €80M ($87.2M USD)

Real Madrid academy product. Currently tearing up Serie A with Como — 13 goals, 7 assists in 40 appearances, dragging the club into the Champions League for the first time. Madrid is already triggering his €8M buyback clause this summer. That's a €72M markup in one season.

Oh, and his first Argentina cap? He assisted Messi. Literally set up Leo's goal in his international debut. If Argentina is going to defend the title, Paz will be riding shotgun with the GOAT.

Rayan — Brazil, 19 years old

Value: €40M ($43.6M USD)

Came to the Premier League as Semenyo's replacement at Bournemouth. Half a season later: 15 games, 5 goals, 2 assists. Carlo Ancelotti looked at Brazil's stacked attacking options — Martinelli, Gabriel Jesus, Richarlison — and said "nah, I want the kid."

Rayan made his second Brazil appearance two days before the roster was announced and scored immediately. He's the chaos agent off the bench that every World Cup winner needs.

Mario Vušković — Croatia, 19 years old

Value: €60M ($65.4M USD)

Croatia's squad is aging — Modrić is pushing 41, Perišić isn't far behind. But in Vušković, they have the next defensive cornerstone. At 6'4" (1.93m), he dominates aerially and has already established himself in the Bundesliga.

Four senior caps, one goal already. Vušković is following the Joško Gvardiol blueprint: unknown before the tournament, un-buyable after it.
