Mario Hermoso's special derby against Real Madrid: Mourinho handed him his debut in 2012

The clash between Roma and Real Madrid at the Stadio Olimpico carries extra meaning for Mario Hermoso. The Madrid-born centre-back, raised in the Real Madrid academy and with a five-year spell at Atletico between 2019 and 2024, experiences this tie as a personal derby. Jose Mourinho's presence on the Roma bench adds even more spice to the occasion, because it was the Portuguese coach who handed him his first-team debut more than a decade ago.

• Mario Hermoso made his Real Madrid debut in 2012, aged 17, under Jose Mourinho.
• It came at the Santiago Bernabeu Trophy against Millonarios, in a historic 8-0 win.
• He never played an official match for Real Madrid and moved to Espanyol.
• After his time at Atletico and a loan spell at Bayer Leverkusen, he is now a key figure at Gasperini's Roma.
• Roma are already working on a contract extension until 2029, breaking their own policy for over-30s.

Mario Hermoso's debut under Mourinho at the Bernabeu Trophy

Back in 2012, Mario Hermoso was splitting his time between the Juvenil B squad, coached by Fernando Morientes, and school. That year's Bernabeu Trophy pitted Real Madrid against Millonarios in a match that served as a tribute to Alfredo Di Stefano. With the score already comfortable, Mourinho brought the young centre-back on in the 74th minute, replacing Raul Albiol. Real Madrid ended up winning 8-0, the biggest victory in the tournament's history.

"Mario and Derik are going to be the most famous kids at school tomorrow," Mourinho joked after that match.

Hermoso later recalled the mix of nerves and excitement of that moment. He was in class when he got the news at lunchtime, and admitted the hardest part was waiting for kick-off. On the Bernabeu pitch, aged 17, he felt he was living the dream that every academy player in the club shares: making a first-team debut in the stadium that was once their home.

From Juvenil B to Espanyol: a farewell without an official debut

That Bernabeu Trophy friendly did not lead to further first-team opportunities. Hermoso kept progressing through the academy ranks, but the door to the senior side did not open again. His move to Espanyol allowed him to grow as a professional and establish himself in the top flight. Even so, he never turned his back on his Madrid past: he has always stressed that he owes Real Madrid practically everything he learned, both personally and professionally.

His performances in Cornella earned him a move to Atletico Madrid in 2019, where he spent five seasons before leaving on a free transfer. Roma signed him in 2024, and after a loan move to Bayer Leverkusen in the second half of the 2024-25 campaign, he has returned to the Italian capital to become a vital cog in Gian Piero Gasperini's system.

Hermoso's revival at Gasperini's Roma

The Madrid-born centre-back has established himself in Gasperini's 1-3-4-2-1 formation. The Italian coach is full of praise for a player he describes as the embodiment of grit and technique, part of a backline he calls a group of "gladiators". Gasperini acknowledges that Hermoso arrived from a difficult experience, but insists he is now one of the best defenders in Europe.

The numbers back that up. Hermoso scored the 89th-minute goal that sparked the comeback against Atalanta (2-1) and is currently the second defender in Serie A with the most ball recoveries (34) and the third with the most interceptions (17). His ambition is clear: he wants to see Roma compete in the Champions League on a regular basis and believes the team is ready to go toe-to-toe with any opponent.

Roma want to lock down their gladiator defender until 2029

Hermoso's form has not gone unnoticed in the boardroom at the Olimpico. His contract was automatically extended until 2027 at the end of last season, but the club wants more. Roma's hierarchy is considering offering him a new deal until 2029, a decision that would break their usual policy of renewing players over 30 on a year-by-year basis.

At 31, Hermoso has earned an exception that Roma rarely grant. His consistency, leadership and ability to adapt to Gasperini's demanding system have made him a fundamental asset for both the present and the future of the Romanista project.

What is at stake for Roma against Real Madrid at the Olimpico

The meeting with Real Madrid comes at a sweet moment for both Roma and Hermoso. The Italian side, fighting to cement a Champions League spot in Serie A, face the European tie as a test of maturity. For the Spanish centre-back, it is also a chance to show his former club that the teenager who made his debut on a summer night at the Bernabeu has become a top-level defender.

The reunion with Mourinho, the coach who trusted him as a teenager, adds an emotional layer to the tie. What was a symbolic gesture in a friendly back in 2012 has now turned into the responsibility of leading the backline of one of the most in-form teams in Italian football.
