West Ham United have signed right-back Aaron Wan-Bissaka from Manchester United for £15 million on a seven-year contract. The 26-year-old, who began his career at Crystal Palace, returns to London and becomes West Ham's eighth senior signing under new head coach Julen Lopetegui. Wan-Bissaka, known for his defensive prowess, expressed excitement about joining West Ham and playing in London again. The club has been very active in the transfer market, also signing players like Max Kilman, Niclas Fullkrug, and Jean-Clair Todibo, spending around £130 million this summer. West Ham technical director Tim Steidten praised Wan-Bissaka as a talented and versatile defender. Meanwhile, Manchester United is reportedly planning to replace him with Bayern Munich's Noussair Mazraoui.
