Spain coach Luis de la Fuente has quelled the doubts around him by leading his country to Nations League glory and ending a decade-long trophy drought.

La Roja needed penalties to see off Croatia and triumph in Rotterdam, but doing so helped ease tensions following their Euro 2024 qualifying defeat by Scotland in March.

De la Fuente's appointment by the Spanish Football Federation (RFEF) to replace Luis Enrique raised eyebrows -- the 61-year-old is a relative unknown as a coach, having worked within the country's youth ranks from 2013 onwards.

After an unconvincing performance in a win over Norway in his opening game, defeat in Glasgow sparked alarm.

However, matches three and four proved far more enjoyable for the coach, beating Italy and then Croatia to lift the cup.

Although the Nations League is a new competition, this only its third edition, Spain and De la Fuente are hopeful that it can prove a springboard for more success, with the waters now more tranquil around him.

"All projects are better constructed on a base of victory and this gives us more strength, confidence, calm," said the coach.

One of De la Fuente's biggest choices has been a shift to a 4-2-3-1 formation, instead of Spain's typical 4-3-3.

The key cog is Manchester City midfielder Rodri, who was named the player of the Nations League finals.

While Luis Enrique drew criticism for playing Rodri as a centre-back at the 2022 World Cup to make room for veteran Sergio Busquets, his successor has reinstalled him in the centre of the pitch.

Rodri, arguably the best in the world in his position, linked well with Mikel Merino against Italy and then Fabian Ruiz against Croatia.

Speaking with clarity and confidence and leading by example on the pitch, Rodri has become his country's torchbearer.

"This generation promises a lot," he said after the Nations League triumph. Before, he had called for Spain to start a new winning cycle.

Rodri's emergence as the team's "frontman" is in part due to an absence of star power in the attack, with Spain boasting a host of dangerous -- but not elite -- forwards.

Barcelona's Ansu Fati was bright off the bench against Croatia and showed he can have a big impact if he can stay fit, while Yeremy Pino, Dani Olmo and Marco Asensio are all similarly bright, but inconsistent.

Alvaro Morata has played at many of Europe's top sides without fully convincing, while back-up striker Joselu has just joined Real Madrid, his career best form coming at the ripe age of 33.

Spain could not find a breakthrough against Croatia and needed penalties to triumph, which De la Fuente said added extra spice to the victory.

"We deserved to win before, but the penalties give it a dash of the epic," said the coach, who expects to continue thriving.

"Obviously, winning gives you more shine, and I expect more joy to come in the future."
