Varney is on loan at Hillsborough, where he has scored nine goals in 32 outings for the Yorkshire club.
"I feel I've not really been given a chance at Derby," the 27-year-old told the Derby Telegraph. "The manager (Nigel Clough) has sent me out on loan to get game time and score goals, which I've done, but I still can't get in the team when I go back."
The Leicester-born striker concedes he may be forced to move away from Pride Park to resurrect his career and admits he would relish a move to his hometown club.
He added: "I suppose I'm in the shop window. Of course, I'd love to come to Leicester."
