Lukaku told Voetbal International: "It is said that the clubs are lining up to loan me and that is true. I even heard that Anderlecht want me back. The club that wants me most is my preference.
"I want to be number one for Belgium, but our other strikers are not standing still. Something has to change."
Lukaku even suggested that could be the Chelsea manager, but added: "Do not get me wrong, I have no problem with Andre Villas-Boas. He is just under a lot of pressure."
