Wharton is a sought-after player, with top European clubs such as Liverpool, Bayern Munich, and others showing interest in signing him.
Notably, his former club, Blackburn Rovers, will receive a 15% share of any profit made from Wharton's sale, as he was purchased by Palace for £18m in January 2024.
According to reports, Wharton is content with his current situation at Selhurst Park and is open to staying with the team for another season.
Crystal Palace is eager to retain Wharton's services, as they face competition from other clubs seeking to sign players like Ebere Eze and Marc Guehi.
