The 40-year-old Australian will be a free agent at the end of the season, while the Cottagers have recently been linked with a number of replacements.
When asked if he is in negotiations with the Premier League outfit, Schwarzer told The Mirror: "Not at the moment, no. I'm just trying to do the best I can and we'll see what happens at the end of the season.
"I have a contract until the end of the season and we will wait and see."
Schwarzer joined Fulham on a free transfer from Middlesbrough in 2008.
