Aston Villa have signed Belgian midfielder Amadou Onana from Everton for £50 million, marking their eighth signing of the summer after qualifying for the 2024/25 UEFA Champions League. Onana replaces Douglas Luiz, who moved to Juventus, and was persuaded by compatriot Youri Tielemans to join Villa. Onana is noted for his defensive abilities, including strong tackling and aerial prowess. Everton, amid financial difficulties, benefit from the sale but face the challenge of replacing Onana. Villa's active transfer window also includes potential deals like trading Jacob Ramsey for Tottenham's Giovani Lo Celso.
