Sienna Wareing Joins West Ham as Hammers Back Young Lioness for WSL Future | OneFootball

West Ham United have confirmed the signing of Sienna Wareing, the highly-rated England youth international midfielder, ahead of the 2026/27 Barclays Women’s Super League season.

The Hammers are building a squad with genuine long-term intent, and securing one of the country’s brightest young midfield prospects is exactly the kind of low-risk, high-upside business that signals a club thinking beyond short-term survival.

Wareing arrives with an impressive pedigree

Wareing has progressed through the England Young Lionesses set-up, earning her reputation as a technically accomplished central midfielder with the composure and passing range to operate at the highest levels of the game.

She is comfortable sitting deep to help build attacks or pushing higher to support play in advanced areas – a versatility that gives manager Rehanne Skinner genuine tactical options.

Her performances at youth level have earned her regular involvement with England’s Young Lionesses, where she has gained valuable experience competing against some of Europe’s most talented young players.

That experience in a high-performance international environment is precisely the kind of pressure-test that accelerates a young player’s development – and it is the platform from which Wareing now makes the step into senior WSL football.

Those who have followed the England youth programme will know that the Young Lionesses system has produced some genuine talent in recent cycles.

As the recent recognition of senior Lionesses underlines, the England football pathway carries real prestige – and Wareing’s involvement in it speaks to her standing among her age group.

The signing reflects a deliberate strategy from West Ham

This is not a panic buy or a short-term fix. West Ham have shown a clear willingness to trust emerging players with meaningful minutes, and Wareing fits that philosophy precisely.

That decision says plenty about where the club sees itself heading – not simply treading water in the middle of the table, but building something with structural depth.

Wareing is the latest arrival in what has been an active summer for the Hammers. The club has continued to add quality across the squad, and her signing continues that momentum. For supporters tracking the full picture of this window, the WSL transfer window framework for 2026/27 sets out the timeline within which these deals are being completed.

Speaking after completing the move, Wareing expressed her delight at joining West Ham and described the opportunity as an exciting next step in her development.

The midfielder admitted she is looking forward to meeting her new teammates, working with the coaching staff and embracing the challenge of playing in the Women’s Super League.

Pre-season gives Wareing time to settle before the competitive calendar begins

With pre-season now underway, Wareing will have the coming weeks to build relationships and adjust to the intensity of senior football before league action starts. Supporters may need patience as she finds her footing – that is the reality for any player making this step – but the attributes are clearly there.

West Ham have their Young Lioness. Now it is over to Skinner to give her the environment to flourish.
