Palace welcome back Man Utd signing Zaha
United have signed Zaha, but the youngster will spend the rest of the season on-loan at Palace.
Crystal Palace co-chairman Steve Parish added: "I feel this a great deal for the club and the player.
"We would like to thank Wilf for all he has done for the club and we all wish him well when he joins Manchester United in the summer.
"It was essential to Wilf and ourselves that he stayed at Palace for the remainder of this season to help the club with its main aim of promotion to the Premier League."
