Daniel de Ridder has been linked with a move to Israeli side Hapoel Tel-Aviv while Erik Edman has been linked with a move to Sheffield United.
Martinez has already sold Won-Hee Cho and Olivier Kapo in the January transfer window.
Martinez told the Wigan Evening Post: “There has been interest in Daniel and Erik, but obviously it has to be the right thing for both the player and the football club.
“I’m sure that there will be some more movement before the window closes.”
