Jim Bentley has said that falling crowd numbers could impact on Morecambe's ability to make signings in the January transfer window.
The club has an average attendance of 1,809 at the Globe Arena this season, the third-lowest in League Two.
The manager told BBC Radio Lancashire: "It's a massive worry because we budget for a certain amount per game and we're dipping well below that at the moment.
"All this talk about me being able to strengthen in January and get fresh bodies in - it's hard to do because we haven't got the pennies because of the attendances.
"We've got a good core of 1,000 or so, who come to every game and will always stand by the club, and the away attendances this season have been very good. It's the ones in between, who can't make their minds up between going to watch a Premier League club, going shopping or watching their local side - they're the ones we've got to get a grip of and get them through the gate."
Morecambe face Dagenham and Redbridge tomorrow.
