The Reason Real Madrid Possess 'Total Trust' in Youngster Thiago Pitarch
Whenever a 18-year-old makes club history in a pivotal Champions League match against City, it naturally attracts acclaim and attention.
In only his maiden start in the competition - and fifth game for the club - Thiago Pitarch 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 made his club debut in the qualifying round a few weeks prior with a substitute appearance at Sporting Lisbon, then assisted Los Blancos defeat the English champions in Tuesday's second leg to confirm a last eight berth.
At 18 years and 226 days, Pitarch was the club'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.
Rapid Ascent Through La Fabrica
The midfielder is the most recent to emerge from the famed youth system and is rapidly cementing himself as one of the manager's most exciting protegees.
He joined Madrid from Leganes in 2023, having formerly spent time at Atletico Madrid and Getafe youth teams, and starting out for the under-19 side, where he rapidly created a positive impact.
Pitarch progressed to the reserve side and it was during a pre-season game in which they faced the academy's first team, then managed by Arbeloa, where the youngster is said to have caught the attention of the present manager, who took over from Xabi Alonso in the new year.
Spanish media would later describe the moment as "an instant connection," noting he stood out not only for his skill on the ball, but for the energy, personality and determination he added to the side.
'His Best Attribute Remains His Personality'
During the pre-season of 2025, ex-manager Xabi Alonso called up the youngster to practice with the first team and awarded him playing time during the warm-up matches.
However, it was the change in manager that became the turning point in his development as he came on as a late substitute in both ties against the Portuguese side that set up 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, every day you go to train and each day you play a match," said Pitarch following his first appearance.
"I've just achieved my dream with the best team in the world and in the top tournament."
Given a first start in the Spanish league against Getafe - where he spent four years after moving from Atletico in 2018 - he has retained his spot for the next four as fitness issues to Bellingham and Dani Ceballos provided an opportunity.
Pitarch has seized it with displays that have belied his age and inexperience.
"He's a very quick player, and you can observe his capabilities," remarked the coach. "He is incredibly energetic, with excellent endurance, work-rate and mobility."
Pitarch's mentality has also impressed his coach.
"His standout trait is his character," added Arbeloa. "He always wants the possession, and even under pressure, he remains unfazed.
"I understand people are surprised to watch him make his debut in a European fixture, but he's playing because I had complete confidence in him to perform his normal game.
"He will keep receiving opportunities with the main squad. It's a pleasure to have a talent like him."
Spain or Morocco?
Born in a Madrid suburb, in the Madrid region, and was raised fully immersed in the local game, progressing through youth setups before entering Real Madrid's famous La Fabrica system.
He holds dual Moroccan and Spanish citizenship, offering him the option to play for either country at the highest level.
According to international regulations, footballers may appear for multiple nations at youth level without being locked in, with the ultimate choice only binding once they play in a competitive full international.
Pitarch has played for the Spanish national team at underage levels, representing both the U19 and under-20 teams, and took part in the 2025 Youth World Cup, where Spain reached the quarter-finals.
Despite this, he has yet to commit to either senior national team, who are watching his progress with interest.
In a recent interview, the player confirmed: "I haven't made my ultimate choice yet. My situation is positive with Spain, but I will reach a decision soon."
This scenario mirrors that of other dual nationality players such as club colleague Diaz and Barcelona forward Lamine Yamal. While teenage Lamine opted for La Roja, Diaz opted to represent Morocco.
Focus on the Future
At present, his attention is on establishing himself in the Madrid lineup and rewarding his manager's belief.
He played 74 minutes in the two-one victory at the Etihad, which sealed a 5-1 aggregate success and a last-eight matchup with the German champions.
He was replaced by fellow youth graduate in Manuel Angel underscored Arbeloa's trust in the next generation to aid the team chase future success.
Following his impressive impact to date on European football's biggest stage, the midfielder is expected to play a key role in that.
"Arbeloa treats me the identical way. We handle it very normally. I try not to overanalyze it too much - I have to deserve my minutes on the field," he said following the win at Etihad Stadium.
