The Belgian international has been linked with a move away from Craven Cottage all summer, with reports indicating that Real Madrid are interested in signing him.
However, despite being happy at his current employers, the 25-year-old has admitted that he wants to play at the highest possible level that he can.
"Personally, I would like to go to the top. I think every player wants that. But I have the confidence to say that I want to play at a top club one day," Dembele told Sport 1.
"[Fulham] is a good team. We have had two good matches now so it also makes sense to play here.
"As long as there is no bid, nothing happens."
