West Ham Women’s summer has moved past simple squad filling. The arrival of Nadine Riesen, confirmed by the Barclays WSL after her Eintracht Frankfurt exit, gives Rita Guarino’s rebuild a much clearer shape: more international experience, more athletic width and a side designed to play higher up the pitch.
Riesen has signed a three-year deal and becomes the club’s fourth senior addition of the window after Katie Zelem, Constance Picaud and Laia Codina. That sequence matters. West Ham are not just adding isolated names; they are building a spine of players who have already handled elite dressing rooms, Champions League pressure or major international tournaments.
For a club that has spent too many WSL seasons operating in survival mode, this is a different type of recruitment message.
Guarino Is Adding Players Who Change The Pitch
Riesen’s profile is especially useful because she addresses one of the most difficult areas to recruit well: full-back. According to the Barclays WSL announcement, the Switzerland international arrives with UEFA Women’s Champions League experience and has played in Switzerland and Germany’s top divisions.
The numbers behind the move sharpen the picture. Riesen made 69 appearances for Eintracht Frankfurt and supplied nine assists, while also building a senior Switzerland career that had reached 42 caps by the time of the announcement. She also featured in all four of Switzerland’s UEFA Women’s Euro 2025 matches and scored in the group stage against Norway.
That gives Guarino a full-back who is not merely defensive cover. Riesen can carry the ball, repeat high-intensity runs and give West Ham a more natural attacking outlet from wide zones. In practical terms, that helps the Hammers stretch compact opponents and gives the midfield a cleaner passing angle when pressure arrives centrally.
It also connects with the club’s wider summer logic. Zelem’s permanent move, confirmed by West Ham’s official site, gives Guarino control and leadership in midfield. Codina adds a World Cup-winning defender’s authority. Picaud raises the goalkeeper standard. Riesen adds width, pace and recovery power.
This Is A Rebuild With A Tactical Thread
The temptation with a busy window is to count signings rather than assess fit. West Ham’s work looks more coherent than that. Guarino appears to be building a side with stronger rest-defence, better first-phase security and enough wide acceleration to attack without leaving the back line exposed.
That is where Riesen becomes particularly interesting. West Ham have too often lacked the ability to turn possession into territorial pressure. A full-back comfortable stepping forward changes the rhythm of attacks: the winger can come inside, the No.8 has a short passing option, and the centre-back has an outlet that does not immediately invite a turnover.
For Zelem, that could be significant. A midfielder of her passing range needs movement ahead of her, not static lanes. If Riesen and the opposite full-back can pin opponents back, West Ham can ask Zelem to dictate tempo rather than constantly firefight in transition.
The internal challenge is still obvious. New signings do not automatically create chemistry, and Guarino must blend different leagues, languages and tactical habits quickly. But the profile mix is encouraging because it targets specific weaknesses rather than chasing reputation alone.
West Ham Have Raised The Standard Of The Dressing Room
The wider significance is cultural. Riesen spoke of Guarino’s ambition and the potential of the group, while the head coach highlighted her pace, attacking quality and resilience. Those are not throwaway traits in a league where the middle tier is becoming brutally competitive.
West Ham do not need to pretend they are closing the gap to Chelsea, Arsenal or Manchester City in one window. The more realistic aim is to become harder to play through, more dangerous from wide areas and less dependent on isolated moments.
That is why this signing feels more important than a routine free transfer. Riesen gives Guarino a player who fits the tactical direction, strengthens the squad’s athletic baseline and adds another experienced voice to a changing dressing room.
For supporters tracking the summer, the clue is not just who West Ham have signed. It is how neatly the pieces now fit together.
