The new deal will keep the 23-year-old at Vitesse until the summer of 2015.
“As a trainer, I can only be very satisfied with this news,” Vitesse coach John van den Brom told AD. “Wilfried is not our first-choice striker for nothing.
“He is young and talented. I am convinced that he is much better and certainly will play at the highest level possible. Until then, he sits firmly in place with us.”
