Manchester City Sign Marc Guéhi from Crystal Palace for £20 Million. The 25-year-old England centre-back joins Manchester City on a five-and-a-half-year deal until June 2031, taking the No. 15 shirt amid injuries to Ruben Dias, John Stones, and Josko Gvardiol. Guéhi, a Chelsea academy product who became a Palace captain, called City 'the best club in England' and praised the rocking Etihad atmosphere.
