Spain and Lamine Yamal have grown through the tournament to leave him with the world at his feet and football’s two greatest prizes in his pocket.
As well as having glorious natural gifts, he is also Spain’s lucky charm. They completed their domination of the international stage with Ferran Torres’ decisive 106th-minute strike in extra time.
Lamine Yamal has yet to lose for his country in the 28 competitive matches he has played. He has started 13 games at major tournaments and won all of them – the longest 100% win rate of any European player across major tournaments when starting.
He also became – along with 19-year-old Spain team-mate Pau Cubarsi – just the fourth and fifth teenagers to start a World Cup final and win, after Pele for Brazil in 1958, Italy defender Giuseppe Bergomi in 1982 and Kylian Mbappe with France in 2018.
Spain coach Luis de la Fuente spoke afterwards of his “sincere gratitude” to Lamine Yamal.
“He has played great football that will help him to mature and be even a greater footballer than he already is,” he said.
“He really sacrificed for the collective good. This is very important in my squad. In my opinion he played a great World Cup.”
And this is not simply a special talent, it is a special talent with a special temperament.
He shrugged off Argentina’s obvious attempts to intimidate him as he regularly came into close contact with Nicolas Tagliafico in particular.
Former England goalkeeper and BBC Sport pundit Joe Hart summed it up well.
“Not only did Lamine Yamal not react,” he said. “He stood up to it. He was not rattled and he did not back down. He had the entire team trying to smash him.
“He just stayed real cool. It was real standout performance from him.
“Lamine Yamal is 19 years old. What a beautiful day for him. He’s 19 and has completed football.”
With virtually his whole career in front of him, and taking in the experience and influence of Spain team-mates such as his captain and player of the tournament Rodri, there is every chance Lamine Yamal will add more successes like this before he is done.
