The Defining Moment
Osasuna’s 2026/27 season has been defined by the quietest of certainties in a summer of significant change. While the club navigated the departure of Víctor Muñoz to Liverpool for a fee approaching €40 million, the arrival of a new manager in Luis Miguel Ramis, and a squad in transition, the goalkeeping department remained untouched. Sergio Herrera, the guardian of the Rojillo goal for eight consecutive seasons, retained his position as the undisputed first choice. Aitor Fernández, the reliable deputy, remained as his alternative.
The defining moment of Osasuna’s goalkeeping season came not in a save or a clean sheet but in the club’s decision to leave the position entirely alone. In a summer where the squad was described as “muy reconocible” and the transfer market “muy tranquilo,” the goalkeeping hierarchy was the one area where Ramis and the sporting directorate felt no intervention was required. Herrera’s experience, his command of the penalty area, and his understanding of the club’s defensive structure made him the natural incumbent. Fernández’s reliability, his professionalism, and his readiness when called upon made him the ideal backup.
The early returns have vindicated that faith. Herrera has started five La Liga matches, accumulating 450 minutes, conceding eight goals, and keeping two clean sheets. Fernández has started four matches in relief, accumulating 360 minutes, conceding ten goals, and keeping one clean sheet. The numbers are not elite, but they reflect a goalkeeping department operating behind a defence that has itself been in transition under a new manager. The stability between the posts has been a rare constant.
This is the story of Osasuna’s 2026/27 goalkeepers: an experienced incumbent defying age, a reliable deputy waiting for his moments, and a pipeline of young talent that ensures the position remains secure for years to come.
Tactical Context
Ramis inherited a squad accustomed to the pragmatic, defensively organised approach that has defined Osasuna’s eight consecutive seasons in La Liga. The new manager’s preference for a 4-2-3-1 system, with a double pivot screening the back four and the full-backs encouraged to advance selectively, places significant demands on the goalkeeper. Herrera is not asked to be a sweeper-keeper in the mould of Ederson or Alisson; he is asked to be a shot-stopper, a commander of his area, and a reliable distributor when the ball is played back to him under pressure.
The statistics from the early part of the season reflect Herrera’s role. In five league appearances, he has made six catches, two blocks, and faced 450 minutes of football. His save percentage and command of the penalty area have been reliable, even as Osasuna’s defensive structure has fluctuated during Ramis’s adaptation period. The club’s record of eighteen goals conceded in nine league matches is concerning, but the goalkeeping department has not been the primary source of the problem.
Fernández’s role is more circumscribed. The 35-year-old, who joined Osasuna in 2021 after spells at Athletic Club and Levante, is expected to feature in the Copa del Rey and during periods of fixture congestion. His experience and professionalism make him an ideal deputy, a player who accepts his role without complaint and performs when called upon. The challenge for Ramis is managing the expectations of a goalkeeper who is good enough to start for many La Liga sides but has chosen to remain as Herrera’s understudy.
The structural question is not whether Osasuna have a capable first choice. They do. The question is how long the current arrangement can last. Herrera is 33, Fernández is 35, and the pipeline behind them—Mikel Bermejo and Rafa Fernández—is talented but unproven. The club’s ability to manage the transition from the current generation to the next will determine whether the goalkeeping department remains a source of strength.
The Goalkeepers
Sergio Herrera
Herrera is Osasuna’s first-choice goalkeeper, the undisputed occupant of the position he has made his own since arriving from Huesca in 2017, and the most experienced voice in the defensive unit. The 33-year-old has started five La Liga matches this season, accumulating 450 minutes, conceding eight goals, and keeping two clean sheets. His three yellow cards reflect the combative nature of his game, but they also illustrate his willingness to put his body on the line for the team.
His profile is that of the complete, traditional goalkeeper. At 192cm, Herrera possesses the physical frame to dominate his penalty area, and his shot-stopping is among the most reliable in the division. His distribution is functional rather than spectacular, but his composure under pressure and his understanding of Osasuna’s defensive structure allow him to play his part in the team’s build-up play. His performance against Real Madrid in the 2024/25 season, where he produced a string of saves that secured a memorable victory, remains the defining night of his recent career.
The contract situation is settled for now, but it requires attention. Herrera’s deal expires in June 2027, and Osasuna will need to address his renewal during the season. At 33, he is entering the twilight of his career, but his form and fitness suggest he has several seasons remaining at the top level. The question is whether the club sees him as the long-term solution or as a bridge to the next generation.
Aitor Fernández
Fernández is Osasuna’s second-choice goalkeeper, the reliable deputy who has occupied the role with patience and professionalism since arriving from Levante in 2021. The 35-year-old has started four La Liga matches this season, accumulating 360 minutes, conceding ten goals, and keeping one clean sheet. His twelve saves and three parries reflect a goalkeeper who is called upon irregularly but performs when required.
His profile is that of the experienced, technically gifted goalkeeper. At 182cm, Fernández is smaller than Herrera, but his reflexes and agility compensate for any physical disadvantage. His distribution is reliable, and his reading of the game allows him to anticipate danger before it materialises. His performance against Barcelona in the 2023/24 season, where he produced a string of saves that secured a draw at the Camp Nou, remains the standout moment of his Osasuna career.
The challenge for Fernández is opportunity. Herrera’s durability has limited the backup goalkeeper’s chances in recent seasons, and the Copa del Rey is likely to be his primary avenue for playing time. At 35, he is at a stage of his career where regular football is essential, but his commitment to Osasuna and his acceptance of a supporting role have made him an invaluable squad member. His contract also expires in June 2027, and the club will need to decide whether to extend his deal or allow him to seek regular football elsewhere.
Mikel Bermejo
Bermejo is the young goalkeeper who has been included in Osasuna’s first-team squad and represents the next generation of talent emerging from Tajonar. The 17-year-old has yet to make a competitive appearance for the first team, but his inclusion in the squad reflects the club’s commitment to developing internal options.
His profile is that of the promising, young goalkeeper. Bermejo’s development will be carefully managed, with opportunities likely to come in cup competitions or during periods of injury crisis. At 17, he has time to learn from Herrera and Fernández, two experienced professionals who understand the demands of La Liga football.
Rafa Fernández
Rafa Fernández is the 22-year-old goalkeeper who has also been included in the first-team squad and represents the pipeline of young talent at the club. His development has been steady, and his presence in the squad provides emergency cover and competition for the backup role.
The challenge for Rafa is patience. With Herrera and Aitor Fernández ahead of him, opportunities will be limited in the short term. His development will be monitored closely as the club plans for the eventual succession to the current generation.

Tactical Identity & Squad Balance
Osasuna’s goalkeeping department is a study in continuity and experience. The club has two veterans in Herrera and Fernández, both in their thirties, both under contract until 2027, and both capable of performing at La Liga level. The balance is not between present and future—it is between two experienced professionals who have shared the position with professionalism and mutual respect.
The structural question is not whether Osasuna have a capable goalkeeper. They do. The question is how the club manages the transition from the current generation to the next. Herrera and Fernández are both in the twilight of their careers, and the pipeline behind them—Bermejo and Rafa Fernández—is talented but unproven. The club’s ability to develop these young goalkeepers and integrate them into the first-team environment will determine whether the position remains a source of strength.
The statistical profile reflects the transition. Osasuna’s eighteen goals conceded in nine league matches is a concerning figure, but the goalkeeping department has not been the primary source of the problem. The defence in front of them has been in flux, with injuries to key players and the adaptation to Ramis’s new system creating instability. Herrera’s two clean sheets and Fernández’s one reflect a goalkeeping department performing admirably under difficult circumstances.
The Verdict from the Camp
OneFootball, on the goalkeeping hierarchy:
“In goal there are no doubts. Sergio Herrera will continue to be the guardian of the Rojillo goal, with Aitor Fernández as an alternative.”
On the contract situation:
“Additionally, the club will have to address during the season the renewals of Aitor Fernández, Lucas Torró, Moi Gómez, Rubén García and Budimir, all of them with contracts until June 2027.”
On the squad number assignments:
“1- S. Herrera, 13- Aitor Fdez., 32- Mikel Bermejo, 31- Rafael Fernández Rodríguez.”
Where Next?
Osasuna’s goalkeeping priority is renewal. Herrera and Fernández are both under contract until June 2027, and the club will need to decide whether to extend their deals or begin planning for the succession. Herrera, at 33, remains the first choice and has shown no signs of decline. Fernández, at 35, is a reliable deputy but may seek regular football elsewhere if the opportunity arises.
The longer-term question is the development of the young goalkeepers. Bermejo and Rafa Fernández represent the future, but they need time and opportunities to prove themselves. The Copa del Rey may provide those opportunities, and the club’s coaching staff will be monitoring their progress closely.
For now, the Rojillos have a goalkeeper they trust, a deputy they respect, and a pipeline that continues to produce. In a season of transition under Ramis, the foundation between the posts remains secure. The question is not whether Osasuna’s goalkeeping is good enough to compete in La Liga—Herrera’s experience and Fernández’s reliability suggest it is. The question is how long the club can keep both of them satisfied, and whether the next generation is ready when the time comes.
