Whenever a 18-year-old creates club history in a pivotal European tie against Manchester City, it naturally attracts praise and attention.
In only his first start in the competition - and fifth game for the team - the young midfielder made a strong impression as the fifteen-time Champions League winners claimed a three-nil last-16 first-leg advantage at the Santiago Bernabeu.
The young player, who also had his Real debut in the play-off round a month ago with a cameo off the bench at Sporting Lisbon, then helped Los Blancos overcome the English champions in the midweek second leg to confirm a quarter-final berth.
At 18 years and 226 days, the midfielder became the team's most youthful starter to begin two matches in the Champions League's latter rounds, beating Brazil forward Vinicius Jr's previous mark by 10 days.
This talent is the most recent to emerge from the famed youth system and is quickly establishing himself as one of Alvaro Arbeloa's most promising protegees.
He signed for Madrid from Leganes in 2023, having previously been with Atletico and Getafe's academies, and initially featuring for the Juvenil C team, where he quickly made a positive impact.
Pitarch progressed to the B team and it was in a pre-season game in which they faced the academy's first team, then managed by the former defender, where the youngster is said to have drawn the eye of the present manager, who replaced Xabi Alonso in the new year.
Reports would later describe the moment as "love at first sight," adding he stood out not only for his skill on the ball, but for the energy, character and drive he brought to the side.
In the summer of 2025, former boss Alonso invited Pitarch to train with the first team and awarded him playing time during the warm-up matches.
However, it was the change in manager that proved the defining moment in his development as he was introduced as a late substitute in both ties against Benfica that set up the meeting with Manchester City.
"I have dreamed of this each night before going to bed, the first day I started playing football, every day you head to training and each day you play a match," said Pitarch after his first appearance.
"I have just achieved my dream with the greatest club in the planet and in the best competition."
Handed a starting debut in the Spanish league against his former club - where he was for several seasons after arriving from Atletico in 2018 - he has kept his place for the following four as injuries to Bellingham and Dani Ceballos provided an opening.
Pitarch has taken it with displays that have defied his age and inexperience.
"He's a very quick footballer, and you can observe his capabilities," said Arbeloa. "He's extremely energetic, with excellent endurance, effort and mobility."
Pitarch's mentality has also stood out to his manager.
"His greatest quality is his character," continued Arbeloa. "He constantly demands the ball, and when pressed, he doesn't feel it.
"I realize people are surprised to see him make his debut in a European fixture, but he is selected because I had complete trust in him to perform what he usually does.
"He will keep receiving chances with the first team. It is delightful to coach a player like him."
Pitarch was born in Fuenlabrada, in the Madrid region, and grew up deeply involved in the local game, moving through local academies before joining the club's renowned La Fabrica system.
He holds dual Spanish and Moroccan nationality, offering him the option to play for either country at senior international level.
Under Fifa eligibility rules, footballers may appear for different countries at youth level without being permanently tied, with the ultimate choice only final once they play in a competitive senior international match.
He has played for the Spanish national team at underage levels, representing both the U19 and under-20 sides, and participated in the 2025 Youth World Cup, where Spain reached the quarter-finals.
Nevertheless, he has yet to commit to any senior national team, who are watching his progress with interest.
In a recent interview, Pitarch said: "I haven't made my final decision so far. My situation is great with the Spanish federation, but I'll make a decision in the near future."
This scenario echoes that of other dual nationality talents such as club colleague Brahim Diaz and Barca star Lamine Yamal. Whereas 18-year-old Lamine chose Spain, Brahim opted to play for Morocco.
At present, Pitarch's focus is on establishing himself in the Madrid lineup and rewarding Arbeloa's faith.
He played 74 minutes in the 2-1 victory at the Etihad, which sealed a five-one overall triumph and a quarter-final tie with Bayern Munich.
His substitution by fellow youth graduate in Angel to emphasise the coach's confidence in younger players to aid the team chase trophies to come.
After his notable contributions to date on European football's biggest stage, Pitarch is expected to play a key role in that.
"Arbeloa treats me the identical way. We deal with it very naturally. I attempt not to overanalyze it too much - I must earn my minutes on the pitch," he said following the win at Etihad Stadium.
