Smith, however, is keeping his decisions to himself as he and his players focus on securing the Saddlers' League One safety with just two matches remaining.
The likes of David Grof, Jimmy Walker, Manny Smith, Anton Peterlin and Emmanuel Ledesma are among those whose terms are set to expire.
Smith told the Express & Star: "I know already but that's for me to sit down with them when the time is right. I want to be safe before I sit down and talk to them - and that's as much their job as it is mine.
"Their job is to get the points we need to give us League One security. Once they do that, I can sit down and start chatting to them."
