When an teenage makes Real Madrid a historic moment in a pivotal Champions League match against City, it inevitably draws acclaim and attention.
During his maiden start in the competition - and fifth game for the club - the young midfielder made a strong impression as the fifteen-time Champions League winners secured a 3-0 round of 16 first leg lead at the Bernabeu.
The young player, who also made his club debut in the qualifying round a month ago with a substitute appearance at Benfica, then assisted the Madrid side defeat the English champions in the midweek second leg to confirm a quarter-final berth.
Aged 18 years and 226 days, the midfielder was the team's youngest player to start twice in the Champions League's latter rounds, beating Brazil forward Vinicius Jr's record by 10 days.
The midfielder is the most recent to emerge from the club's academy and is rapidly cementing himself as one of the manager's most exciting young players.
He signed for Real from CD Leganes in 2023, having formerly spent time at Atletico and Getafe's academies, and initially featuring for the Juvenil C team, where he rapidly created a strong impression.
He progressed to the B team and it was during a pre-season game in which they played against the academy's first team, then managed by the former defender, where the youngster is said to have drawn the eye of the current Real boss, who took over from Xabi Alonso in January.
Reports would later label the moment as "an instant connection," noting he excelled not only for his technical ability, but for the vitality, personality and determination he added to the side.
During the summer of 2025, former boss Alonso called up the youngster to practice with the senior squad and awarded him playing time in the warm-up matches.
However, it was the change in manager that became the defining moment in his career as he was introduced as a second-half replacement in each leg against the Portuguese side that set up the meeting with Pep Guardiola's team.
"I have dreamed of this each night before going to bed, the first day I began playing the game, every day you head to training and each day you play a match," stated Pitarch following his debut.
"I've just achieved my dream with the best team in the world and in the top tournament."
Handed a first start in La Liga against Getafe - where he was for four years after arriving from Atleti in 2018 - he has kept his place for the following four as fitness issues to Bellingham and Dani Ceballos created an opportunity.
Pitarch has seized it with displays that have defied his age and inexperience.
"He's a extremely fast player, and you can see what he's capable of," remarked the coach. "He is extremely energetic, with excellent endurance, effort and mobility."
The player's mindset has also stood out to his manager.
"His greatest quality is his personality," added Arbeloa. "He constantly demands the ball, and when pressed, he remains unfazed.
"I realize fans might be astonished to see him start in a European fixture, but he is selected because I had complete trust in him to perform his normal game.
"He will continue to get opportunities with the first team. It is delightful to coach a talent like him."
Born in Fuenlabrada, in the Madrid region, and was raised fully immersed in the local game, moving through local academies before entering the club's renowned youth academy.
He possesses dual Spanish and Moroccan citizenship, offering him the option to represent either country at the highest level.
Under international regulations, footballers may represent different countries at junior level without being locked in, with the final decision only binding once they play in a competitive senior international match.
Pitarch has played for the Spanish national team at youth level, turning out for both the under-19 and under-20 sides, and took part in the 2025 Youth World Cup, where Spain reached the quarter-finals.
Nevertheless, he has yet to commit to any full national side, who are watching his rise with keen attention.
Speaking recently, Pitarch confirmed: "I have not taken my final decision yet. Things are positive with Spain, but I will reach a conclusion soon."
His situation echoes that of other bi-national players such as Real team-mate Brahim Diaz and Barcelona forward Lamine Yamal. While teenage Yamal opted for Spain, Brahim decided to represent the Atlas Lions.
For now, Pitarch's focus is on establishing himself in the Madrid lineup and repaying his manager's belief.
He featured for 74 minutes in the two-one victory at City, which completed a 5-1 aggregate success and a last-eight tie with the German champions.
He was replaced by fellow youth graduate in Manuel Angel underscored the coach's confidence in younger players to aid the team chase future success.
After his impressive impact to date on European football's biggest stage, Pitarch is expected to play a key role in that.
"The manager handles me the identical way. We deal with it very naturally. I attempt not to think about it too much - I must deserve my minutes on the field," he commented following the win at Manchester.
