The 40-year old Australian goalkeeper comes out of contract at the end of the season but insists he is in talks to extend his stay at Craven Cottage.
"I feel really good and don't think the age thing is hindering my performances in any way," Schwarzer told SBS The World Game.
"I've had some initial discussions and the intentions are there at the club to keep me.
"But in what capacity we'll have to wait and see. I want to be playing each week - that's the key for me. I love playing and don't want to be No.2 anywhere.
"The World Cup is also a huge priority and the reality is if I am not playing I don't think it would be possible to be a part of the national team.
"I just want to be out there enjoying every minute - especially at this stage of my career.
"If that means I have to move on at the end of the season, then that's fine also. Let's just see how we go."
