Oso in 2026: Net Worth and Salary, Height, FC 26, Position, Transfer Values, and FAQs

Who Is Oso?

If you follow La Liga or keep up with rising football talent in Europe, chances are you have come across the name Oso. His real name is Joaquin Martinez Gauna, and he is a 23 year old left back currently playing for Sevilla FC in Spain's top division. Born in Torrevieja, a coastal town in Alicante, to Argentine parents, Oso carries dual nationality. He is Spanish by birth but proudly Argentine in his roots. That cultural mix has shaped who he is both on and off the pitch.

He got his start at grassroots clubs like Algorfa and Kelme before moving through the youth academies at Real Murcia and Malaga. Sevilla signed him in July 2022, and he spent time developing with Sevilla Atletico (the reserve side) before earning his spot in the senior squad. He made his first team debut in December 2023 and has not really looked back since.

Early Life and Background

Oso grew up in Torrevieja, a city on Spain's southeastern coast. His parents are Argentine, and he has spoken openly about how his father raised him with a deep love for Argentine football, particularly River Plate. In an interview, he mentioned waking up at four in the morning to watch River Plate matches from Spain. That kind of passion tells you a lot about his character.

He was not always a left back. Earlier in his youth career he played in more attacking roles, but it was during his time at Sevilla Atletico that he was converted into a left back. That switch turned out to be the best thing that could have happened to his career. His pace, energy, and ability to get forward make him a natural fit for the modern fullback role.

Club Career

Oso joined Malaga's youth setup in 2018 and eventually made his senior debut with Atletico Malagueno (Malaga's reserve team) in October 2021. He scored his first senior goal in April 2022 against UD San Pedro. That performance caught the eye of scouts, and by July 2022, Sevilla had signed him on a three year deal.

He initially played for Sevilla Atletico in the Segunda Federacion before getting promoted. His Copa del Rey debut came in December 2023, and from the 2024/25 season onwards, he started getting more minutes with the first team. In the 2025/26 season, Oso made around 27 appearances for Sevilla, scoring 2 goals and providing 3 assists across all competitions. Those numbers are solid for a defender, especially one still finding his feet at the highest level.

He renewed his contract in February 2024, extending his stay until June 2027. His brother, Gabri Martinez, is also a footballer and currently plays for UCAM Murcia B.

Position and Playing Style

Oso primarily operates as a left back, though he can also play as a left wing back or left midfielder depending on the formation. He is left footed, which gives him a natural advantage on that side of the pitch. What stands out about Oso is his directness. He likes to get forward, cross the ball into the box, and is not afraid to take on a shot from distance.

Defensively, he is still developing. Some scouting reports have pointed out that his tackling and positional awareness need work, but his energy and willingness to track back are positives. At just 23, there is plenty of room for growth. His strengths lie in his pace, his crossing ability, and his direct free kicks.

FC 26 Stats and Rating

In EA Sports FC 26, Oso has an overall rating of 72 with a potential of 80. That makes him one of those hidden gems in Career Mode that a lot of players look for. He plays as a left back in the game, has 2 star skill moves and a 2 star weak foot rating. His work rates are medium/medium, which means the AI version of him holds a balanced position on the pitch.

For anyone building a La Liga squad in Career Mode or looking for a cheap, high potential fullback, Oso is a smart pick. His stats should grow nicely over a few in game seasons if you give him regular playing time.

Transfer Values

Oso's market value has seen a massive jump in recent years. Back in June 2025, his estimated value was around 200,000 euros. By mid 2026, that figure had climbed to approximately 10 million euros according to multiple football data platforms. His release clause at Sevilla is reportedly set at 20 million euros, but given that he only has one year left on his deal, reports suggest that a move could happen for around 10 to 12 million euros.

Several clubs have shown interest. Nottingham Forest, Newcastle United, Tottenham, and Fiorentina have all been linked with him during the summer 2026 transfer window. Fiorentina reportedly offered around 12 million euros with a sell on clause. Whether Oso stays at Sevilla or moves to a new league remains one of the interesting transfer stories of the summer.

Net Worth and Salary

Exact salary figures for Oso are not publicly confirmed, but based on what we know about Sevilla's wage structure (the average first team salary at the club is around 2.2 million euros per year), it is fair to estimate that Oso earns somewhere between 500,000 and 1 million euros per year. As a younger squad player who has only recently broken into the first team, his wages are likely on the lower end of the squad's pay scale.

Icon Polls estimates that Oso's net worth in 2026 is between 1 million to 2 million dollars. This factors in his salary, endorsement potential, bonuses, and market value. If he secures a move to the Premier League or another high paying league, that figure could rise significantly in the coming years.

Height and Physical Stats

Oso stands at 1.83 metres tall, which is about 6 feet even. He weighs around 70 kg (154 lbs). For a left back, that is a solid frame. He is not overly physical, but his height gives him a decent aerial presence, and his lean build helps with his pace and agility on the flanks.
