RC Strasbourg sign Oso from Sevilla for €10m as the French club look to strengthen their left side and add another young, technically capable defender to Hugo Oliveira’s squad.
The transfer was completed on August 29, with the 23-year-old Spanish left-footer moving from Sevilla to Strasbourg for a reported €10 million fee. Oso arrives in France after making an encouraging start to the 2026/27 LaLiga season, including a goal and an assist across his first two league appearances.
For Cambodian football fans who follow European transfer news, this is an interesting move because Strasbourg are investing in a player who has already shown that he can contribute at senior level while still having considerable room to develop.
Oso Gives Strasbourg a Left-Footed Defensive Option
One of the clearest reasons behind the transfer is Oso’s profile.
Standing at 1.83 metres, the Spanish defender is naturally left-footed and can operate along the left side of the defensive line. That gives Strasbourg another option in an area where balance and progression from the back are particularly important.
His arrival also fits the club’s current situation.
Strasbourg have taken three points from their opening two Ligue 1 matches, beating Lens 2-1 before suffering a heavy 4-0 defeat away to Marseille. They have scored two goals but conceded five, meaning defensive stability remains an important priority.
Oso joins RC Strasbourg from Sevilla for €10 millionWhat Oso Brings to Strasbourg
Oso’s early 2026/27 numbers provide plenty of encouragement.
He played 156 minutes across two LaLiga appearances for Sevilla, scoring once and providing one assist. He also earned a place in the Team of the Week during that early-season spell and recorded a 7.25 Sofascore Rating.
His defensive statistics are particularly interesting.
Oso won 5 of 6 aerial duels, giving him an impressive 83.3% success rate. He also completed 3 of 4 tackles, while contributing four total shots and 13 accurate passes into the final third.
Those numbers suggest a defender who is not simply focused on stopping attacks.
His ability to progress the ball and contribute further up the pitch could be valuable for Strasbourg, especially when the team needs to move quickly from defensive situations into attack.
Speed Could Be Another Major Asset
Oso also brings useful physical qualities.
The 23-year-old recorded 22 sprints during his early LaLiga appearances and reached a top speed of 31.85 km/h.
That pace could be particularly useful in Ligue 1, where transitions and open spaces can play a major role.
Strasbourg have already demonstrated a willingness to attack quickly. According to the Sofascore data, they have recorded a fast-break goal during their opening two league matches. Oso’s speed could therefore complement a team that wants to move the ball forward quickly after winning possession.
A Potential Fit for Hugo Oliveira’s System
The tactical question will be how quickly Oso adapts to Oliveira’s system.
Strasbourg have averaged around 42.5% possession across their opening two Ligue 1 matches, suggesting that they are comfortable playing without dominating the ball.
That style can create significant opportunities for a defender who is capable of defending space, winning aerial challenges and making accurate forward passes.
Oso’s left foot gives the coach an additional passing angle during build-up, while his pace can help cover space when Strasbourg push their full-backs higher.
For Cambodian fans watching Ligue 1, his development will be particularly interesting because he represents the type of young player who could become more important as the season progresses.
Oso’s Impressive Start at Sevilla
Before moving to France, Oso had been progressing through Sevilla’s system.
He joined Sevilla Atlético after moving from Málaga’s youth setup and gradually worked his way toward the first team. Sevilla’s official announcement states that he made 27 first-team appearances, contributing three goals and four assists overall.
His breakthrough accelerated during 2025/26.
He made 21 first-team appearances during that campaign, scoring twice and providing three assists, before adding another goal and assist at the beginning of the new season.
That recent improvement helped increase his value in the transfer market.
Sevilla’s decision to sell now therefore represents a significant piece of business, particularly for a player who developed through the club’s pathway.
Why €10 Million Could Be Good Business
The reported €10 million transfer fee represents a significant investment for Strasbourg, but the club are not simply buying a short-term solution.
They are acquiring a 23-year-old player with top-flight experience, technical ability and physical upside.
Sofascore’s available profile places Oso’s estimated market value at around €10.5 million, which is close to the reported transfer fee.
That makes the move look relatively logical from Strasbourg’s perspective.
If Oso establishes himself as a regular Ligue 1 starter, his value could increase significantly over the next few seasons.

For Sevilla, the transfer also represents an important piece of squad and financial management.
Oso progressed from the club’s academy pathway to the first team, meaning the €10 million sale provides a direct financial return on that development.
The official Sevilla announcement confirms that Oso leaves after 27 first-team appearances, with three goals and four assists.
The club can now reinvest the transfer income into other areas of the squad while continuing to develop younger players.
There is also an element of timing.
Oso had started the new LaLiga campaign positively, so his market value was moving in the right direction. Strasbourg have effectively taken the opportunity to secure him before his price could potentially rise further.
Strasbourg’s Left Side Gets More Competition
The immediate question for Strasbourg supporters will be whether Oso walks straight into the starting XI.
His defensive numbers suggest that he has the tools to compete for minutes, but adapting to a new country, new league and new tactical system will take time.
The positive is that Strasbourg have not signed a player with no senior experience.
Oso has already played in LaLiga and has shown that he can contribute both defensively and offensively.
His 83.3% aerial-duel success, 75% tackle success and 31.85 km/h top speed provide an encouraging statistical profile.
What Cambodian Fans Should Watch
For Cambodian football fans following Ligue 1, there are three areas worth watching when Oso makes his Strasbourg debut:
- Defensive duels — Can he maintain his strong aerial and tackling numbers?
- Build-up play — How effectively can his left foot help Strasbourg progress from defence?
- Transitions — Can his pace help Strasbourg defend counterattacks and launch attacks quickly?
If he performs well in those areas, Strasbourg could have found an important long-term piece for their squad.

Final Verdict
The RC Strasbourg sign Oso from Sevilla for €10m transfer looks like a calculated investment rather than a short-term reaction.
At 23, Oso already has senior LaLiga experience, strong early-season numbers and a profile that fits Strasbourg’s need for greater balance on the left side.
His ability to win aerial duels, make tackles, progress the ball and accelerate into space gives Hugo Oliveira several useful tactical options.
For Sevilla, the deal provides a healthy financial return on a player developed through their system. For Strasbourg, it represents an opportunity to develop a promising young defender into an established Ligue 1 player.
The biggest challenge will be adaptation.
But if Oso can reproduce the qualities he displayed at Sevilla — particularly his defensive efficiency, left-footed distribution and pace — €10 million could eventually look like a very smart investment for Strasbourg.
For Cambodian fans looking for a new Ligue 1 player to follow, Oso is certainly one name worth keeping an eye on this season. ⚽🇫🇷
