Argentina and Spain clash at MetLife Stadium, New Jersey, on Sunday in what is set to be an intense clash between two sides who are in formidable form.
Having already won the European Championship in 2024, Cucurella is hoping to help Spain to their first World Cup title since 2010, when Andres Iniesta bagged the goal in a 1-0 win over the Netherlands.
Cucurella has played every single minute of the tournament so far as manager Luis de la Fuente puts faith in the defender, who signed for Real Madrid this summer, as he departed Chelsea in a £51.8 million deal.
Ahead of the game, Cucurella has revealed that he will go to extremes if he is crowned a world champion, even going as far as to retire at just 27 years old.
"If we win the World Cup, I'll call Luis the next day and tell him not to count on me anymore, that I'm retiring from the national team," he said. "With a European Championship and a World Cup, I can't do any better."
In a separate interview, he also stated: "I would get a little tattoo of Spain manager Luis de la Fuente's face on my bicep if we were to win the World Cup."
The Madrid star is just days away from turning 28 years old, meaning if he did retire, it would come as a huge shock, as he will only be 30 years old at the Euros in 2028. If Spain do lift the title, fans will be eager to see if he follows through with his plan.
