A host of players are expected to be sold after the club slid into League One but Marshall does not expect the phone to be ringing.
He told the Norwich Evening News: "We've taken the club down. It's not as if there are boys in there, superstars, who are going to get good moves when they're getting relegated so we just have to plug on.
"Sometimes it's out of some of the boys' hands but the board decide it.
"I've no problems staying here because I don't think there are clubs lining up for any of the boys when we've just had 46 games to stay in the Championship and got relegated."
