Riesen Joins West Ham’s Summer Rebuild
West Ham United have bolstered their defensive ranks by signing Swiss international Nadine Riesen on a three-year contract. The 26-year-old full-back joins after her departure from German side Eintracht Frankfurt, where she made 69 appearances in the Frauen-Bundesliga between 2023 and 2026.
Riesen becomes manager Rita Guarino’s fourth summer acquisition as the Hammers reshape their squad. She follows midfielders Katie Zelem and Constance Picaud, plus defender Laia Codina through the door, signaling an ambitious window for the Women’s Super League outfit.
“When I heard about West Ham’s interest in me, I was super excited. It’s a huge club with a proud history and I’m very happy to be here,” said Riesen. “The WSL is one of the best leagues in the world so this is a massive opportunity for me to continue my development in a new environment, challenge myself and keep doing what I love most.”
Guarino’s Defensive Reinforcement
Head coach Rita Guarino has prioritized adding pace and attacking intent to her backline, and Riesen fits the profile perfectly. The Swiss defender’s ability to operate as a full-back on either flank provides tactical flexibility, while her experience in the Women’s Champions League brings a European pedigree that can elevate the squad.
“She is a full-back with pace and attacking quality that will complement our playing style,” Guarino explained. “Nadine works extremely hard for the team and has a never-say-die attitude, which is something that we value within this group. Over the last few years, she has grown into an important player for her national team and that experience will be really valuable for us.”
Riesen’s arrival addresses a key area of need for West Ham, who have been working to close the gap on the WSL’s top sides. Her defensive solidity and overlapping runs will be crucial as the Hammers aim to improve upon a mid-table finish last season.
What Riesen Brings to the WSL
With 42 international caps for Switzerland, Riesen is no stranger to the big stage. She featured in all four of her country’s matches at Euro 2025, scoring against Norway on home soil. That tournament experience, coupled with her time in the tough Frauen-Bundesliga, suggests she will adapt quickly to the physicality and tempo of English football.
Riesen’s versatility is a major asset. Primarily a right-back, she is equally comfortable on the left, which gives Guarino options in how she sets up. Her crossing accuracy and willingness to join attacks add another dimension to West Ham’s offensive play, while her one-on-one defending has been honed against some of Europe’s best wingers.
The signing also reflects West Ham’s growing ambition in the women’s game. Guarino, given a longer contract in the summer, has been backed in the transfer market, and Riesen’s arrival is a statement of intent. With the spine of the team now reinforced, the Hammers look better equipped to challenge for a top-half finish and perhaps more.
