For victory over Burnley, he scored twice for the second successive game as the soaring Eagles made it six wins and a draw in seven matches.
Palace boss Dougie Freedman said: “Wilfried took his goals well and played well.
“Was it his best-ever performance for Palace? Not really.
“I’ve set very high standards for him. Wilfried shows his performances and consistency most weeks. He’s a young man with huge potential. Let’s hope he can fulfil that — and this is the best place to fulfil it."
