Why Real Madrid Possess 'Total Trust' in Teenager Pitarch
Whenever a 18-year-old creates club a historic moment in a pivotal Champions League match against City, it naturally attracts acclaim and the spotlight.
During his maiden start in the tournament - and fifth game for the club - the young midfielder made a strong impression as the 15-time European champions secured a three-nil last-16 first-leg advantage at the Santiago Bernabeu.
The teenager, who also had his Real debut in the qualifying round a month ago with a substitute appearance at Sporting Lisbon, then assisted the Madrid side overcome the English Premier League side in Tuesday's return to secure a quarter-final place.
At 18 years old, Pitarch was the team's youngest player to begin two matches in the Champions League's latter rounds, surpassing Brazil forward Vinicius Jr's record by 10 days.
A Meteoric Rise From The Academy
This talent is the most recent to come through from the famed youth system and is quickly establishing himself as one of the manager's most exciting young players.
He signed for Madrid from Leganes in the summer of 2023, having formerly spent time at Atletico Madrid and Getafe's academies, and starting out for the under-19 side, where he rapidly created a strong impression.
He worked his way up to the reserve side and it was in a pre-season game in which they faced the academy's first team, then managed by Arbeloa, where the youngster is said to have drawn the eye of the present manager, who replaced the previous coach in the new year.
Spanish media would later describe the moment as "an instant connection," noting Pitarch stood out not only for his technical ability, but for the energy, personality and determination he added to the team.
'His Greatest Quality Is His Character'
During the pre-season of 2025, ex-manager Xabi Alonso invited the youngster to practice with the first team and awarded him playing time in the warm-up matches.
However, it was the change in manager that proved the turning point in his career as he was introduced as a second-half replacement in both ties against the Portuguese side that led to the clash with Pep Guardiola's team.
"I've dreamed of this each night before going to bed, the first day I began playing the game, each day you head to training and every day you have a game," said the player after his first appearance.
"I have just fulfilled my ambition with the best team in the planet and in the best competition."
Handed a starting debut in the Spanish league against Getafe - where he spent four years after moving from Atleti in 2018 - he has retained his spot for the next four as fitness issues to Jude Bellingham and Ceballos provided an opportunity.
Pitarch has seized it with performances that have defied his age and experience.
"He's a extremely fast player, and you can observe what he's capable of," remarked Arbeloa. "He's incredibly energetic, with excellent stamina, work-rate and movement."
Pitarch's mentality has also impressed his coach.
"His standout trait is his character," continued Arbeloa. "He always wants the ball, and even under pressure, he doesn't feel it.
"I understand fans might be astonished to watch him make his debut in a European fixture, but he's playing because I had total confidence in him to perform his normal game.
"Thiago will keep receiving chances with the main squad. It's a pleasure to have a player like him."
A Future International Decision
Born in Fuenlabrada, in the Spanish capital's community, and grew up fully immersed in the local game, progressing through youth setups before joining Real Madrid's renowned La Fabrica system.
He possesses dual Spanish and Moroccan citizenship, giving him the option to play for either country at the highest level.
Under Fifa eligibility rules, footballers may represent different countries at junior level without being permanently tied, with the ultimate choice only binding once they play in a official senior international match.
Pitarch has played for Spain at youth level, turning out for both the under-19 and U20 teams, and took part in the 2025 Fifa Under-20 World Cup, where La Roja reached the last eight.
Despite this, he has yet to commit to any full national side, who are watching his rise with keen attention.
In a recent interview, the player confirmed: "I have not taken my final decision yet. Things are great with the Spanish federation, but I'll make a conclusion soon."
His situation mirrors that of other bi-national players such as Real team-mate Brahim Diaz and Barcelona forward Lamine Yamal. Whereas teenage Lamine chose Spain, Brahim opted to play for the Atlas Lions.
Eyes on the Prize
For now, his attention is on making his mark in the Madrid lineup and rewarding his manager's belief.
He featured for 74 minutes in the 2-1 victory at the Etihad, which sealed a five-one overall triumph and a quarter-final tie with the German champions.
His substitution by fellow youth graduate in Manuel Angel to emphasise Arbeloa's trust in the next generation to aid the team pursue future success.
Following his notable contributions to date on European football's biggest stage, the midfielder is expected to play a key role in that.
"Arbeloa handles me the identical way. We deal with it very naturally. I try not to overanalyze it too much - I must deserve my playing time on the pitch," he said following the win at Etihad Stadium.
