The Red Devils face a hectic schedule after a raft of postponements including Saturday's clash with Stevenage.
"Everyone was gutted on Saturday when the game was called off so late so there was plenty of energy spent at training on Sunday," Gregory told the club website.
"We're just desperate to get a run of games under our belt. The remaining fixture list is quite daunting when you look at it but we will cope.
"In fact we should embrace the challenge and I'm sure we will. I think, on our day, that we are as good as any side in this division and we have proved that with some of our results."
