When Kylian Mbappé and Lamine Yamal take the field at AT&T Stadium in Arlington, Texas, on Tuesday evening, they will not only be fighting for a place in the final on Sunday but will lead the most expensive group of stars ever assembled in a men's World Cup semifinal. According to the latest data from Transfermarkt, the French national team is valued at approximately $1.78 billion (€1.56 billion), while Spain's is valued at $1.43 billion (€1.25 billion). The total value is around $3.2 billion (€2.8 billion), surpassing any previous semifinal in the tournament's history. The lion's share of this amount comes from several key players. Lamine Yamal of Barcelona, who turned 19 a day before the match, is the most expensive player remaining in the tournament: his market value is estimated at about $234 million (€205 million), with Mbappé not far behind at around $211 million (€185 million). Next are Michael Olise and Pedri, each valued at approximately $176 million (€154 million). Together, this quartet represents four of the five most expensive footballers in the world. The fifth is Norwegian Erling Haaland, whose national team did not reach this stage, losing to England. France's greatest superiority lies in attack: forwards, including Ousmane Dembélé and Désiré Doué, bring the total value of the attacking line to about $878 million (€770 million). This is significantly higher than Spain's, whose attacking group, even with Yamal, is valued at $489 million (€428 million). France is also ahead in defense: defenders are valued at $473 million (€414 million) compared to Spain's $337 million (€295 million). However, the advantage for Spain lies in goalkeeping: their goalkeepers are valued at a total of $113 million (€99 million), while the French goalkeepers are valued at $67 million (€58 million).
