As the afternoon wore on, more people stopped to watch Mateo play.
The square became an impromptu showcase, with the local children organizing increasingly elaborate games to display their friend's abilities. Mateo seemed to thrive on the attention, his play becoming even more creative and audacious.
He nutmegged Luis three times in a single sequence, each one more outrageous than the last. He scored a goal by flicking the ball up with his heel, letting it bounce off his shoulder, and volleying it into the goal with his weaker left foot.
He even attempted and successfully completed a rainbow flick that sent the ball sailing over two defenders before bringing it down with a perfect first touch.
"El niño mágico," someone in the crowd murmured, and the nickname stuck immediately.
The magic boy.
It was a title that captured both Mateo's extraordinary ability and the sense of wonder he inspired in everyone who watched him play. In a neighborhood where football was taken seriously, where every child dreamed of following in the footsteps of their heroes, Mateo had established himself as something special.
As the sun began to set, casting long shadows across the square, Mateo reluctantly prepared to return to the orphanage. Don Carlos had given him permission to play in the neighborhood, but he was expected back for dinner and evening studies.
"Will you come back tomorrow?" Jordi asked hopefully.
"Sí," Mateo replied with a smile. "I'll always come back."
The walk back to Casa de los Niños took him through the winding streets of Gràcia, past the shops and cafés where his reputation was already beginning to spread.
Señora García waved from her flower shop, and the barista at Café Central gave him a thumbs-up through the window. In the space of a few months, Mateo had become a neighborhood celebrity.
But fame, even on such a small scale, came with its own challenges. As Mateo turned onto his street, he found his path blocked by three older boys he didn't recognize. They were probably twelve or thirteen, with the swagger of teenagers who thought they owned the neighborhood.
"So you're the famous magic boy," the tallest one said, his tone carrying a mixture of curiosity and challenge. "We heard you think you're pretty good at football."
Mateo clutched his ball a little tighter but kept his expression neutral. "I just like to play," he said quietly.
"Well, we like to play too," the boy continued. "How about you show us some of this magic we've been hearing about?"
It wasn't really a request.
The three boys spread out, blocking Mateo's escape routes with the practiced efficiency of experienced bullies. But Mateo had learned something important during his months of street football: confidence was often more powerful than size or strength.
"Okay," he said simply, setting his ball down. "But if I show you magic, you have to let me pass."
The boys laughed, but there was uncertainty in their eyes. They had expected fear or pleading, not calm acceptance of their challenge.
What followed was a display of skill that left the would-be bullies speechless. Mateo began with simple juggling, keeping the ball in the air with effortless control.
Then he moved to more complex tricks: around-the-world touches, heel flicks, and combinations that seemed to defy physics.
The crescendo came when he placed the ball on the ground and began to dance around it, his feet moving in intricate patterns that kept the ball perfectly still while he wove around it like a matador working with a bull.
The older boys found themselves stepping back, mesmerized by the display.
"How..." one of them started to ask, but Mateo was already moving.
He flicked the ball up with his toe, caught it on the back of his neck, let it roll down his back, and kicked it up again with his heel. As it descended, he trapped it with his chest, let it drop to his feet, and in one fluid motion, chipped it gently into the hands of the tallest boy.
"Magic," Mateo said with a small smile, then walked past the stunned teenagers toward home.
Behind him, he could hear them arguing about what they had just witnessed, their voices filled with a mixture of awe and disbelief.
But Mateo was already thinking about tomorrow's training session with Señor Vásquez, about the new techniques he wanted to practice, about the dreams that seemed to grow larger with each passing day.
When he arrived at Casa de los Niños, he found Don Carlos waiting in the courtyard with a knowing smile.
"I heard you caused quite a stir in the plaza today," the director said.
"People like to watch football," Mateo replied with the matter-of-fact tone that had become his trademark.
"They like to watch magic," Don Carlos corrected gently. "And you, pequeño, are becoming quite the magician."
That evening, as Mateo practiced his ball control in the courtyard under the watchful eyes of the other orphans, he reflected on the day's events. The attention was flattering, but it also brought pressure and expectations that he was still learning to handle.
Sister María Elena joined him as he worked on his weak-foot shooting, offering encouragement and technical advice. "You're becoming famous in the neighborhood," she observed.
"I just want to get better," Mateo said, concentrating on keeping his shots low and accurate.
"And you will," she assured him. "But remember, with great talent comes great responsibility. People will expect things from you, and not all of them will be fair or reasonable."
Mateo nodded, understanding more than his seven years should have allowed. He had already begun to sense that his gift came with complications as well as opportunities. But he also knew that he wouldn't trade his ability for anything in the world.
As the stars appeared over Barcelona, Mateo made his way to bed, his ball tucked securely under his arm. Tomorrow would bring new challenges, new opportunities to improve, and new chances to experience the pure joy that came from expressing himself through football.
In the neighborhood of Gràcia, the legend of el niño mágico was just beginning to grow. But for Mateo Álvarez, it was simply another step on a journey that he sensed would take him far beyond the narrow streets and small squares where his reputation was being forged.
The magic was real, and it was only getting stronger.
