Whenever a teenage makes club history in a key Champions League tie against Manchester City, it naturally attracts praise and attention.
In only his first start in the tournament - and fifth game for the club - the young midfielder made a strong impression as the fifteen-time European champions claimed a three-nil last-16 first leg lead at the Bernabeu.
The teenager, who also made his Real debut in the qualifying round a month ago with a cameo off the bench at Sporting Lisbon, then assisted the Madrid side overcome the English Premier League side in Tuesday's return to secure a last eight berth.
Aged 18 years and 226 days, the midfielder was the team's youngest player to start twice in the Champions League knockout stages, beating star Vinicius Jr's previous mark by 10 days.
This talent is the latest to emerge from the famed youth system and is quickly establishing himself as one of the manager's most promising protegees.
He signed for Madrid from CD Leganes in the summer of 2023, having formerly spent time at Atletico and Getafe's youth teams, and starting out for the Juvenil C team, where he quickly made a positive impact.
He progressed to the reserve side and it was during a friendly match in which they faced the senior squad, then managed by Arbeloa, where the youngster is said to have caught the attention of the present manager, who replaced Xabi Alonso in January.
Reports would later label the moment as "love at first sight," noting Pitarch stood out not only for his technical ability, but for the vitality, personality and determination he added to the side.
In the pre-season of 2025, ex-manager Xabi Alonso invited Pitarch to practice with the senior squad and awarded him minutes in pre-season.
However, it was the change in manager that became the turning point in his career as he was introduced as a late substitute in both ties against Benfica that set up the meeting with Manchester City.
"I've dreamed of this every night before going to bed, the first day I began playing the game, every day you go to train and every day you have a game," said Pitarch following his debut.
"I have just achieved my ambition with the best team in the world and in the best competition."
Given a starting debut in the Spanish league against his former club - where he was for several seasons after moving from Atletico in 2018 - he has kept his spot for the next four as fitness issues to Bellingham and Dani Ceballos created an opportunity.
Pitarch has seized it with performances that have belied his age and inexperience.
"He's a extremely fast footballer, and you can observe what he's capable of," said Arbeloa. "He is incredibly dynamic, with great stamina, work-rate and mobility."
Pitarch's mentality has also impressed his coach.
"His standout trait is his character," continued Arbeloa. "He always wants the ball, and when pressed, he remains unfazed.
"I understand fans might be astonished to watch him start in a Champions League match, but he's playing because I had total confidence in him to perform his normal game.
"He will keep receiving chances with the main squad. It's a pleasure to coach a player like him."
Pitarch was born in a Madrid suburb, in the Madrid region, and was raised deeply involved in the local game, progressing through youth setups before entering Real Madrid's famous youth academy.
He holds both Spanish and Moroccan nationality, offering him the choice to represent either country at senior international level.
Under international regulations, footballers may represent multiple nations at youth level without being locked in, with the ultimate choice only binding once they play in a official full international.
Pitarch has played for the Spanish national team at underage levels, representing both the under-19 and under-20 sides, and took part in the 2025 Youth World Cup, where La Roja made it to the last eight.
Despite this, he has yet to commit to any full national side, who are watching his progress with interest.
In a recent interview, the player confirmed: "I have not taken my final decision yet. My situation is positive with Spain, but I will reach a conclusion in the near future."
This scenario mirrors that of other bi-national talents such as club colleague Brahim Diaz and Barcelona forward Lamine Yamal. Whereas teenage Lamine chose Spain, Diaz decided to play for the Atlas Lions.
For now, his attention is on establishing himself in the Madrid lineup and rewarding Arbeloa's faith.
He featured for over an hour in the two-one win at City, which sealed a five-one aggregate success and a quarter-final matchup with the German champions.
He was replaced by another academy player in Angel to emphasise the coach's confidence in younger players to aid the team chase trophies to come.
Following his notable contributions to date on European football's biggest stage, the midfielder is tipped to play a key role in that.
"The manager treats me the same. We handle it very normally. I try not to overanalyze it too much - I have to deserve my playing time on the pitch," he commented after the win at Etihad Stadium.
