West Ham United have confirmed that Oona Siren has signed a new two-year contract, with the Finland international committing her future to the Hammers until the summer of 2028.
The announcement is another positive step for the club as preparations continue for the 2026/27 Barclays Women’s Super League season. While summer transfer windows are often defined by new signings, securing the futures of established players is equally important. West Ham have ensured one of their most dependable performers will remain in east London for years to come.

Since arriving from Norwegian side LSK Kvinner in September 2024, Siren has become one of the most influential players in the squad. Calm in possession, intelligent without the ball and relentless in her work rate, the midfielder has developed into a player her teammates can rely on every single week.
The new deal also comes at an exciting time for the club following the appointment of Rita Guarino as head coach. As the experienced Italian prepares for her first campaign in charge, keeping a player of Siren’s quality provides an important foundation to build upon.
Oona Siren happy to continue her journey with West Ham
After signing her new contract, Siren spoke of her happiness at remaining with West Ham. She made it clear she believes there is still plenty to achieve in claret and blue.

The midfielder explained that she feels settled in east London and has enjoyed every aspect of her time at West Ham since arriving almost two years ago. She also praised the people around the club, highlighting the environment that has helped her continue developing both on and off the pitch.
Those comments will no doubt be welcomed by supporters. Modern football moves quickly, and players frequently change clubs in search of new opportunities. However, Siren’s decision to commit her future suggests she believes West Ham is the right place to continue her development.
That confidence appears to be shared by the club. Offering the Finland international a new contract demonstrates just how highly she is regarded. Not only for what she has already achieved, but also for the role she can play in the years ahead.

A move that has worked perfectly for both sides
When West Ham signed Siren from LSK Kvinner in September 2024, the club knew they were bringing in a midfielder with an excellent reputation.
She had already enjoyed success in Finland with KuPS before continuing her development in Norway. There, she gained valuable experience in both league and European football.
Stepping into the Women’s Super League, however, presents a completely different challenge. The pace is faster. The physical battles are tougher. Every opponent has quality throughout the squad.
Despite those demands, Siren adapted impressively and has continued to grow season after season. Rather than simply finding her feet in English football, she has become one of the team’s most dependable performers.

Looking back now, the move has proved to be an excellent piece of recruitment by West Ham.
Why Oona Siren is so important
Every successful team needs balance in midfield.
While attacking players often receive the headlines for scoring goals, midfielders are responsible for controlling matches, protecting the defence and linking play between the two penalty areas.
That is exactly what Siren brings to this West Ham side. She rarely panics when receiving possession. Instead, she constantly scans the pitch, looks for the best option and keeps the ball moving.
Her passing may not always be spectacular, but it is consistently effective. She understands when to slow the game down and when to increase the tempo, giving West Ham far greater control during matches.

Without the ball, she is equally valuable. Her positioning allows her to intercept passes before attacks develop, while her willingness to press opponents often forces mistakes high up the pitch.
She also covers an enormous amount of ground throughout 90 minutes, helping teammates defensively before immediately supporting attacks when possession is regained.
Those qualities are not always reflected in statistics. However, they are exactly the reasons coaches place so much trust in players like Siren.

Consistency has become her trademark
One of Siren’s biggest strengths is consistency.

Every squad has players capable of producing moments of brilliance. Far fewer players are able to perform at a high level every single week. Siren has become one of those dependable footballers.
Whether West Ham are facing title challengers or teams lower down the table, supporters know exactly what they will get from the Finland international.
Siren competes for every ball. She works tirelessly for her teammates. She makes intelligent decisions under pressure, and she never hides when the game becomes difficult. Those characteristics make her an invaluable player.
Rita Guarino inherits a player she can build around
The arrival of Rita Guarino represents the beginning of a new era at West Ham.

The former Juventus head coach arrives with an outstanding reputation after enjoying significant success in Italy, and one of her first priorities will be building a squad capable of competing consistently in the Women’s Super League.
Thankfully for Guarino, she already has several high-quality players at her disposal. Siren is undoubtedly among them.
Midfielders who combine technical quality with tactical intelligence are incredibly valuable.
Siren has shown she can perform in different systems and fulfil a variety of roles depending on what the team requires. Whether playing deeper to protect the defence or slightly further forward to support attacks, she brings calmness and discipline to the middle of the pitch.

Those qualities should make her one of the key players under Guarino. Rather than beginning a new project from scratch, the Italian coach inherits a footballer capable of becoming one of the leaders of her squad.
Experience beyond her years
Although Siren is still only 24 years old, she already possesses significant experience. She has won league titles in Finland and represented them on the international stage. She has also competed in European football.
Each of those experiences has helped shape the player West Ham supporters now see every weekend.
International football, in particular, continues to play an important role in her development. Testing herself against different styles of play and some of Europe’s strongest players ensures she continues learning and improving.

Those experiences naturally benefit West Ham whenever she returns from international duty. With many of her best years still ahead of her, there is every reason to believe Siren can continue reaching even higher levels.

A statement of intent from West Ham
Retaining important players sends a message — it tells supporters the club wants to build rather than restructure.
It tells potential new signings there is stability within the squad. It also gives the coaching staff the continuity required to implement their ideas.
Oona Siren’s new contract achieves all three. Instead of allowing uncertainty to surround one of their most influential players, West Ham have acted early and secured her future.

That provides valuable stability heading into an important season under a new head coach.
Every successful team is built around a dependable core of players. Siren has unquestionably earned her place within that group.
What this means for the season ahead
Expectations around West Ham continue to grow. Supporters have seen encouraging progress in recent seasons and will hope the team can continue moving in the right direction under Guarino. Having players like Siren available will be essential.
Her ability to control games, protect the defence and provide composure in midfield will become even more important as West Ham look to compete consistently against the league’s strongest sides.

The club will also benefit from the understanding she has already developed with her teammates. That familiarity cannot be underestimated.
While new signings often require time to settle, Siren already knows what is expected and can help those arriving this summer adapt more quickly.
Leadership is not always about wearing the captain’s armband. Sometimes it comes from setting standards every day in training and delivering reliable performances every weekend. Siren has shown those qualities throughout her time at West Ham.

Looking to the future
With her future now secure until 2028, Siren can focus entirely on helping West Ham continue progressing.

She has already established herself as one of the team’s most reliable midfielders, but there is every reason to believe her best football is still to come.
The next chapter promises to be an exciting one, with a new manager and a refreshed squad, along with fresh ambitions.
For West Ham supporters, securing the Siren on a new contract is one of the best pieces of business the club could have completed this summer. Keeping one of the squad’s most consistent performers gives Guarino a strong platform to build from as she begins her first season in charge.
For the player, it is recognition of the hard work she has put in since joining the club. For West Ham, it is another statement that they are determined to build a squad capable of competing with the very best in the Women’s Super League.
