Luis de la Fuente's Spain are closing in on greatness. They are bidding to become just the fourth team to hold both the World Cup and European Championship crowns at the same time; following their compatriots in 2010, France in 2000 and West Germany back in 1974.

De la Fuente is now into his fourth year as Spain boss; winning the Euros two years ago and now guiding his country to a quarter-final against Belgium on Friday. France lie in wait for the winners. He has lost just three times since he took over in January 2023, and is on a run of 35 games without a defeat.

There are coaches who build teams through tactics, and there are coaches who build teams through people. De la Fuente somehow manages to do both. What sets him apart though is more than a football philosophy, but rather a way of understanding people. His style can be defined as controlling possession but with alternatives. But alongside it he has created a culture.

De la Fuente's success with Spain is the product of decades of work within the Spanish federation, and of his own role as a coach in that system since 2013, shaping players and instilling values. He has played a crucial part in building a collective identity that is now unmistakable, and that is no small feat with a national side.

The one club man who is Spain's under-the-radar hero Lamine Yamal shows why this could be his World Cup. Spain have only lost three matches since De la Fuente became manager.

At the heart of De la Fuente's world view lies a simple conviction: football is a team sport built by good people. Not 'good' in the abstract moral sense - though Christian values and common sense ethics clearly guide him - but in the footballing sense; generous, supportive, selfless, disciplined, and willing to sacrifice for the collective. He repeats this idea constantly, almost with surprise that anyone finds it unusual.

"Those of us who have been in a locker room know what it means to be a good person," he said in an exclusive chat before the game against Belgium. "Almost every squad has had the opposite, the player who disrupts harmony, who puts himself first."

De la Fuente, 65, has lived through enough dressing rooms to know that talent without generosity does not go far. His Spain is built on players who give before they take. Spain's style has always relied on players who understand the game collectively. The passing, the possession, the positional intelligence: these are technical qualities but social ones too.

Every team left in this World Cup has one thing in common: a clear idea. National teams don't have the time to build the complexity of club sides, so the message has to be simple and repeated. That is where Spain have an advantage.

Their footballing identity has been developed over decades. Players and coaches are selected because they fit the idea, not the other way round. And they have been able to evolve their style because the foundations were already there. Some would argue they have a certain advantage on the national teams that are trying a 'new project' with a new manager.

De la Fuente has inherited that identity, and to paraphrase what Pep Guardiola once said when talking about Johan Cruyff, De la Fuente "has not built the cathedral, he merely re-paints it from time to time". The Spain manager has added layers: more versatility, more depth, more comfort in transitions, more unpredictability in the final third, more solidity.

Spain are still recognisable, still "the easiest team to analyse", as a member of Portugal's staff told me after their defeat in the last 16, but "the hardest to beat." He knows these players because he has worked with them at youth level for a decade. His coaching decisions reflect this familiarity.

His staff logically analyse every match in detail and learn what the adjustments are. Against Cape Verde, Spain lacked finesse in their passing. Against Saudi Arabia, the machine ran smoothly again. Against Uruguay, he knew that Spain had historically lost matches when dragged into provocation and chaos, so he insisted on calmness, discipline, and emotional control.

De la Fuente admits that in earlier years he would have reacted more emotionally. He said: "Experience has taught me to face these situations many times. I've been through these games - I've already lived through them and usually lost. Why? Because we didn't know how to play certain types of games."

"So, when someone rattles you, knocks you off your game, breaks your focus, you find yourself interrupted, paused, with changing disrupting rhythms." It has taught him that Spain lose when they abandon their identity.

His news conferences reflect the same values. He prepares them, with the help of Aitor Karanka, director of football at the federation, the media team and also the FA psychologist, former player Javier Lopez Vallejo, but he improvises when the situation demands it. He speaks from the heart.

He calls journalists by name because he was taught that at home that "respect begins with recognising the person in front of you". He looks people in the eye and treats them as equals. He insists these are not media tricks.

And what of Lamine Yamal, the prodigy whose face appears on every poster, whose talent has already captured the world's imagination? Managing him is one of De la Fuente's most delicate tasks. How is he handling that particular task?

He said: "Well, mostly by staying calm and giving him confidence, because we know where Lamine came from (two months injured before joining Spain this summer) and even though he's not fully there yet in terms of fitness, we also knew that our plans were set for this phase.

"This is where we wanted to see him, and he wants to see himself, and he's already completely focused on making this his World Cup." But De la Fuente knows that greatness is not built in a single match. It is built through maturity.

This is why the Portugal match was, in De la Fuente's eyes, the most important of Lamine's career. Not because he dazzled with the ball, but because he worked relentlessly without it.

"This is the moment for him," De la Fuente says. "Not the moment to score 10 goals, but the moment to be decisive in decisive matches. In my understanding of this sport, success comes with a good team.

If you add some incredible individual players, well, you almost, almost hit perfection, but it's the only way to achieve anything." His admiration for players like Mikel Oyarzabal reveals the same logic. Oyarzabal is, in his view, one of the five best centre‑forwards in the world.

"He is a player who, in different circumstances, would be recognised worldwide as a top player, which, in my opinion, he is, and he's starting to get recognised, but he should have been for a long time," said De la Fuente.

Everything about De la Fuente's life reflects consistency, including training daily himself to stay fit. "Yes, it's a lifestyle," he said. "The most important thing about this is consistency. I've always been taught to be disciplined, consistent.

"I'm exhausting, my friends used to tell me that I am exhausting. When I set my mind to something, I'm one of those who just keeps going." He has only one thing in his mind right now.
