The Reds, almost wound up in November due to a £308,000 tax bill, will boost their coffers by around £100,000 thanks to the third-round win against the League One side and their giant fourth-round tie.
"Financially it's a great boost and I would like to think there will be a big crowd here on Saturday," said Coleman.
"We have never played a Premier club here in my reign and I would like to think we can get a full house.
"The lads have given their all this season, through the good times and the bad times, even when the club and their employment were under threat."
