Whenever a teenage creates club history in a key Champions League match against Manchester City, it naturally attracts praise and the spotlight.
In only his maiden start in the tournament - and fifth appearance for the club - the young midfielder suitably impressed as the 15-time Champions League winners claimed a 3-0 last-16 first leg advantage at the Santiago Bernabeu.
The teenager, who also had his Real debut in the play-off round a few weeks prior with a substitute appearance at Benfica, then assisted Los Blancos overcome the English Premier League side in the midweek return to secure a quarter-final berth.
Aged 18 years old, Pitarch became the team's most youthful starter to begin two matches in the Champions League knockout stages, surpassing Brazil forward Vinicius Jr's previous mark by a week and a half.
This talent is the most recent to come through from the famed youth system and is rapidly cementing himself as one of Alvaro Arbeloa's most promising young players.
He signed for Madrid from CD Leganes in 2023, having previously been with Atletico Madrid and Getafe's academies, and starting out for the under-19 side, where he rapidly created a positive impact.
He progressed to the reserve side and it was in a pre-season game in which they played against the academy's first team, then coached by the former defender, where the youngster is said to have caught the attention of the present manager, who replaced Xabi Alonso in January.
Spanish media would later label the moment as "an instant connection," adding Pitarch stood out not only for his skill on the ball, but for the vitality, personality and determination he added to the side.
In the pre-season of 2025, ex-manager Xabi Alonso called up Pitarch to train with the first team and awarded him playing time during the warm-up matches.
However, it was Arbeloa's appointment that became the turning point in his development as he was introduced as a late substitute in both ties against the Portuguese side that set up the meeting with Pep Guardiola's team.
"I have dreamed of this each night when sleeping, the very first time I started playing the game, each day you go to train and each day you play a match," said the player following his debut.
"I've just fulfilled my dream with the greatest club in the planet and in the top tournament."
Handed a starting debut in La Liga against his former club - where he was for several seasons after moving from Atletico in 2018 - he has retained his spot for the next four as injuries to Bellingham and Dani Ceballos provided an opportunity.
Pitarch has taken it with performances that have belied his age and experience.
"He is a very quick player, and you can observe what he's capable of," remarked Arbeloa. "He is incredibly energetic, with excellent stamina, effort and mobility."
The player's mindset has also impressed his manager.
"His greatest quality is his character," added he. "He constantly demands the ball, and when pressed, he doesn't feel it.
"I realize fans might be astonished to watch him make his debut in a European fixture, but he is selected because I had complete confidence in him to perform what he usually does.
"Thiago will keep receiving chances with the first team. It's a pleasure to have a player like him."
Pitarch was born in Fuenlabrada, in the Spanish capital's community, and was raised fully immersed in Spanish football, moving through youth setups before joining Real Madrid's famous La Fabrica system.
He holds dual Moroccan and Spanish nationality, giving him the option to represent both nations at the highest level.
According to Fifa eligibility rules, players may represent multiple nations at youth level without being locked in, with the final decision only final once they appear in a competitive senior international match.
He has featured for the Spanish national team at youth level, turning out for both the U19 and under-20 teams, and took part in the 2025 Fifa Under-20 World Cup, where La Roja reached the quarter-finals.
Nevertheless, he has yet to commit to either full national side, who are watching his progress with interest.
Speaking recently, Pitarch confirmed: "I have not taken my ultimate choice yet. My situation is great with Spain, but I will reach a conclusion in the near future."
This scenario mirrors that of other dual nationality players such as club colleague Brahim Diaz and Barca star Lamine Yamal. While 18-year-old Yamal opted for Spain, Diaz decided to play for Morocco.
At present, his attention is on making his mark in the Real side and rewarding Arbeloa's faith.
He featured for over an hour in the two-one win at the Etihad, which sealed a 5-1 overall triumph and a last-eight matchup with Bayern Munich.
His substitution by fellow youth graduate in Angel to emphasise Arbeloa's trust in the next generation to help the team chase trophies to come.
Following his notable contributions to date on the Champions League, the midfielder is tipped to play a key role in that.
"Arbeloa handles me the same. We deal with it very naturally. I attempt not to overanalyze it excessively - I must earn my minutes on the field," he said following the success at Etihad Stadium.
