The Reason Real Madrid Possess 'Total Trust' in Youngster Thiago Pitarch
Whenever a 18-year-old creates club a historic moment in a key European tie against City, it inevitably draws acclaim and the spotlight.
In only his first start in the competition - and fifth appearance for the team - Thiago Pitarch suitably impressed as the 15-time Champions League winners claimed a 3-0 last-16 first leg advantage at the Bernabeu.
The young player, who also made his Real debut in the play-off round a month ago with a cameo off the bench at Benfica, then helped the Madrid side defeat the English Premier League side in the midweek second leg to confirm a quarter-final berth.
Aged 18 years old, the midfielder was the club's youngest player to begin two matches in the Champions League knockout stages, beating Brazil forward Vini Jr's record by 10 days.
Rapid Ascent Through The Academy
This talent is the most recent to come through from the famed youth system and is rapidly cementing himself as one of the manager's most exciting protegees.
He signed for Madrid from CD Leganes in 2023, having previously been with Atletico and Getafe youth teams, and initially featuring for the under-19 side, where he rapidly created a strong impression.
Pitarch worked his way up to the B team and it was during a pre-season game in which they faced the senior squad, then coached by Arbeloa, where the youngster is said to have caught the attention of the present manager, who replaced Xabi Alonso in the new year.
Reports would later describe the moment as "love at first sight," adding Pitarch stood out not only for his technical ability, but for the energy, character and determination he brought to the side.
'His Greatest Quality Is His Personality'
During the pre-season of 2025, former boss Xabi Alonso invited Pitarch to train with the senior squad and gave him playing time in the warm-up matches.
However, it was Arbeloa's appointment that became the turning point in his career as he was introduced as a second-half replacement in each leg against Benfica that set up the meeting with Pep Guardiola's team.
"I have dreamed of this every night when sleeping, the first day I began playing football, each day you head to training and every day you have a game," stated Pitarch after his first appearance.
"I have just achieved my dream with the greatest club in the world and in the top tournament."
Handed a first start in La Liga against his former club - where he was for several seasons after moving from Atletico in 2018 - he has retained his place for the following four as fitness issues to Jude Bellingham and Dani Ceballos created an opening.
Pitarch has seized it with performances that have belied his age and experience.
"He is a very quick footballer, and you can observe what he's capable of," said Arbeloa. "He's extremely energetic, with excellent stamina, work-rate and mobility."
Pitarch's mentality has also impressed his manager.
"His standout trait is his personality," added he. "He constantly demands the possession, and even under pressure, he doesn't feel it.
"I understand fans might be astonished to watch him make his debut in a Champions League match, but he is selected because I had total trust in him to do what he usually does.
"He will continue to get chances with the main squad. It is delightful to coach a player like him."
A Future International Decision
Pitarch was born in a Madrid suburb, in the Madrid region, and grew up deeply involved in Spanish football, moving through local academies before entering the club's renowned La Fabrica system.
He possesses both Moroccan and Spanish nationality, offering him the choice to play for either country at the highest level.
Under Fifa eligibility rules, footballers may represent different countries at youth level without being permanently tied, with the ultimate choice only final once they appear in a official senior international match.
He has played for the Spanish national team at underage levels, representing both the U19 and U20 teams, and took part in the 2025 Fifa Under-20 World Cup, where Spain reached the last eight.
Despite this, he has yet to commit to either full national side, who are watching his progress with keen attention.
In a recent interview, the player said: "I have not taken my final decision yet. Things are great with the Spanish federation, but I will reach a conclusion soon."
This scenario echoes that of other bi-national players such as Real team-mate Diaz and Barcelona forward Yamal. While teenage Lamine opted for Spain, Brahim opted to represent the Atlas Lions.
Eyes on the Prize
At present, 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 win at the Etihad, which sealed a five-one aggregate success and a last-eight tie with Bayern Munich.
He was replaced by fellow youth graduate in Manuel Angel to emphasise Arbeloa's trust in the next generation to aid the team pursue future success.
After his notable contributions so far on European football's biggest stage, Pitarch is tipped to be a central figure in that.
"Arbeloa handles me the same. We handle it very normally. I try not to think about it excessively - I must earn my playing time on the pitch," he said after the win at Manchester.
