The anticipation had been building for weeks.
Don Carlos had managed to secure two tickets to FC Barcelona's match against Real Betis, and he had chosen Mateo to accompany him to the Camp Nou.
For a seven-year-old boy whose entire world revolved around football, the opportunity to see his heroes play in person was nothing short of miraculous.
Mateo had barely slept the night before, his mind racing with excitement and wonder.
He had seen the massive stadium on television countless times, but the prospect of actually being there, breathing the same air as Ronaldinho, Xavi, and Iniesta, seemed almost too incredible to believe.
The morning of the match dawned bright and clear, with the kind of crisp autumn air that made Barcelona feel alive with possibility.
Mateo dressed carefully in his best clothes – a simple white shirt and dark trousers that Sister María Elena had pressed specially for the occasion. Around his neck, he wore a small Barcelona scarf that one of the older children had given him as a good luck charm.
"Are you ready, pequeño?" Don Carlos asked as they prepared to leave Casa de los Niños.
Mateo nodded, clutching his football against his chest. He had insisted on bringing it, despite Don Carlos's gentle suggestion that it might be better left at home. The ball had become his constant companion, and the thought of experiencing such an important moment without it felt wrong.
The journey to the Camp Nou took them through the heart of Barcelona, past the Gothic Quarter and along the wide avenues that pulsed with the energy of match day.
Mateo pressed his face against the bus window, watching as the city transformed around them. Fans wearing the distinctive blue and red stripes emerged from metro stations and side streets, their voices already raised in songs that Mateo was beginning to recognize.
"Look," Don Carlos said, pointing ahead as they rounded a corner. "There it is."
Mateo's breath caught in his throat.
The Camp Nou rose before them like a modern colosseum, its massive concrete structure both imposing and beautiful. The stadium seemed to pulse with life, drawing thousands of pilgrims toward its gates with an almost magnetic force.
"It's so big," Mateo whispered, his voice filled with awe.
"The biggest in Europe," Don Carlos confirmed. "Nearly one hundred thousand people can fit inside."
As they approached the stadium, Mateo found himself swept up in the river of humanity flowing toward the entrances.
Families walked together, fathers carrying young children on their shoulders, groups of friends singing traditional Barcelona songs. The atmosphere was electric, charged with the collective passion of supporters who lived and breathed for their club.
But it was the pre-match entertainment that truly captured Mateo's imagination. On the massive screens outside the stadium, highlights from Spain's recent international matches played on loop.
Mateo watched in fascination as Xavi orchestrated play from midfield, his passes finding teammates with surgical precision. Iniesta glided past defenders as if they were standing still, his close control and balance defying belief.
Then came the moment that would change everything.
The screen filled with images of Spain's national team celebrating a recent victory, the players draped in the red and yellow flag as they acknowledged the crowd's adoration. The camera lingered on each player's face, capturing the pure joy and pride that came from representing their country at the highest level.
Mateo felt something stir deep within his chest, a longing so powerful it almost took his breath away. Without thinking, he pointed to the Spanish flag on the screen, then placed his small hand over his heart.
"That," he said to Don Carlos, his voice barely audible above the crowd noise. "I want to do that."
Don Carlos followed Mateo's gaze to the screen, where the Spanish players were now singing their national anthem with tears of pride in their eyes. He understood immediately what the boy meant, and the realization sent a chill down his spine.
"You want to play for Barcelona?" Don Carlos asked gently.
Mateo shook his head, his eyes never leaving the screen. "I want to play for Spain," he said with the quiet certainty that had become his trademark. "I want to wear that shirt and make people proud."
The declaration hung in the air between them, profound in its simplicity. Don Carlos had heard many children express dreams of playing professional football, but this was different.
Mateo wasn't talking about fame or money or even the glory of playing for the world's biggest clubs. He was talking about something deeper, more fundamental – the desire to represent his country, to be part of something greater than himself.
"That's a very big dream, pequeño," Don Carlos said carefully.
"I know," Mateo replied. "But I also know that Barcelona is the way to get there. Look at them: Xavi, Iniesta, Puyol. They all came through La Masia, and now they play for Spain. If I can get to Barcelona, if I can learn from them..."
He didn't finish the sentence, but he didn't need to. Don Carlos could see the entire plan forming in the boy's mind, the pathway from the orphanage to La Masia to the Camp Nou to the Spanish national team. It was audacious in its scope, but Mateo spoke of it with the matter-of-fact tone of someone discussing the weather.
As they made their way into the stadium, Mateo's excitement reached fever pitch.
The concourses were packed with supporters, the air thick with the smell of food and the sound of a dozen different conversations.
Vendors sold scarves and flags, their voices competing with the ambient noise of ninety thousand people preparing for ninety minutes of passion.
Their seats were in the upper tier, but the view was spectacular. The pitch spread out below them like a perfect green carpet, the grass so pristine it seemed to glow under the stadium lights. Mateo had never seen anything so beautiful in his life.
"This is where dreams come true," Don Carlos said, settling into his seat beside the mesmerized boy.
"No," Mateo corrected, his eyes scanning the tunnel where the players would soon emerge. "This is where dreams begin."
