Crystal Palace are interested in signing Youri Baas, a 22-year-old Dutch defender who plays for Ajax, but they face competition from Newcastle United. Both of the Premier League clubs are monitoring his progress and aim to sign him during the January transfer window. For Crystal Palace, Baas is regarded as a potential replacement for club captain Marc Guehi. Guehi's contract expires at the end of the season, and he has been linked with a potential exit in January. The defender's expected cost is around €20 million, though it is not certain if Ajax would agree to sell a key player mid-season. Baas, who joined Ajax in January 2023, is under contract until June 2028. He has not yet made his senior debut for the Netherlands and has made 15 Eredivisie appearances this season, scoring one goal. Transfermarkt estimates his current market value at €16 million.
