But new Palace boss Neil Warnock is confident of hanging onto the youngster. He told the Daily Mail: "He's a Palace nut and I want him to stay for two or three years.
"There are five or six other young players here, such as Victor Moses and John Hills, who can make a name for themselves.
"His position will be central midfield, where he can dictate things and decide when to get things going. He has a good touch and good vision but I will have to tell him to cut out the showboating.
"I remember Palace being billed as the Team of the Eighties and I wanted to recreate that here with the number of young players we have at the club."
