Bentley expects to do limited business this January following the capture of free agent Ryan Williams but feels a good display against the Daggers could inspire locals to return as paying punters and boost the Shrimps' coffers.
"It's a chance to get the community behind the team and see if we can generate some atmosphere," Bentley told BBC Radio Lancashire.
"The situation that the club's in is not ideal. Everyone's feeling the pinch and attendances haven't been what we predicted.
"We're not in a position to go out and get players. We've got to work with what we've got and we've got a squad that will give their all.
"It will be great if we can get a good number (of fans) in and, as I say, they can come back as paying customers. It's the town's football club and we need more and more people to back it."
