Anderlecht hope to bring Defour back to Belgium next month.
Van Holsbeeck said: "Anderlecht will be a good option for him.
"Let's say he joins Fulham, then he will have to settle again.
"At Anderlecht he will be the star. If he wants to be sure of his place in the Belgian World Cup squad, then we are a perfect option. Steven is an intelligent guy. I think he knows this."
