"Giants. Congratulations, world champions," wrote the 40-year-old striker on his social media.

While João Neves, Rafael Leão, Diogo Dalot, João Palhinha, and Rúben Dias shared the FIFA and Portuguese Football Federation's post announcing the national achievement, Vitinha went further: "The future is yours," he wrote.

“Congratulations, lads. Proud of Portugal,” added the midfielder, who on Wednesday was a standout in Paris Saint-Germain's 5-3 victory over Tottenham in the Champions League, scoring his first career hat-trick.

Portugal won its first ever Under-17 World Cup title on 27 November, defeating Austria with a solitary goal from Anísio Cabral in the 32nd minute of the final played in Doha, Qatar.

Bruno Fernandes, for his part, posted a video of the Portuguese youth team's celebrations, thanking “the world champions”.

The reigning European champions, the Portuguese national team, had already secured their best ever performance in the competition, surpassing their third-place finish in 1989, then played in the Under-16 category, with current coach Bino Maçães in the Brazilian squad.

This is Portugal's third world championship title, following their triumphs at the Under-20 World Championships in 1989 in Saudi Arabia and 1991 in Portugal, in both cases under the guidance of Carlos Queiroz.
