Spireites boss Paul Cook is looking forward to taking his side to in-form Southend United tomorrow night.
Like Chesterfield, the Shrimpers are yet to taste defeat in December and currently sit 6th in the table.
Cook acknowledged that Chesterfield will face a tough test at Roots Hall, but was keen to stress that it will also be a difficult night for the home side.
Speaking to Spiretes Player ahead of the game, he said: "It's very much a trip we're looking forward to.
"Southend away is a tough game, so are they all. They're all the same.
"Southend are in good form, they're a very strong club at League Two level, they've got play-off experience, they've got a lot of experienced players. It will be a tough game tomorrow night for us, it will also be a very tough game for Southend."
Chesterfield are unbeaten in 5 games and have moved to within touching distance of the play-off places.
Cook believes that the recent run of form may have alerted promotion rivals that the Spireites mean business.
"We've got good players at Chesterfield, we're a very strong team. I think we've sent a couple of warning signs out to people that our season's not over, our season's got a long, long way to go, we've got a lot to play for and we're happy to go with any team in this league and have a football game," Cook said.
"Tomorrow night at Southend we'll go there to win the match. We'll go there to entertain our travelling support and to come back with 3 points."
