Jon Walters would like to soon open new contract talks with Stoke City.
The striker's current deal expires in 2016.
Walters told the Daily Mail: "It's always at the back of your mind. We haven't had any talks yet. I'm a realist. They're always looking for someone to replace you. It's been no different since I've been here.
"The strikers we've had in: Eidur Gudjohnsen, Michael Owen, John Carew, Kenwyne Jones, Cameron Jerome, Crouchy is here, Mame Biram Diouf. If the club want to keep me, they will come to me."
