West Ham United sign Swiss defender Nadine Riesen on a three-year contract, according to multiple reports. The deal follows Riesen’s departure from German club Eintracht Frankfurt. The move brings another defensive option to West Ham as they add to their squad ahead of the new season. Both outlets state that the signing is completed on a three-year term and that it is directly linked to Riesen leaving Frankfurt. While details beyond the contract length and her club departure are not included in the provided reports, the overall information is consistent: Riesen is a Switzerland international, she plays in a defensive role, and her transfer to West Ham is confirmed after she leaves her previous team. The reports do not specify additional terms such as transfer fees, appearance targets, or whether there are any options to extend the contract.
