The Belgian was linked with Hannover last season, but told the Sunday Mail: "I saw the reports again about me going to Germany but I haven't heard anything.
"Certainly I haven't sought to leave Rangers. All I've been concentrating on is my recovery and comeback.
"I pushed everything to the side and as far as I'm concerned it is just a rumour.
"I have never said I wanted to leave, I'm happy at Rangers. I just have to try to force myself back into the team."
