Spireites skipper Sam Hird has urged his side to continue their impressive run during the festive season in the hope that Chesterfield can propel themselves into the League Two play-off places for the first time this season.
Paul Cook's side have managed to put together a run that has seen them suffer just one defeat in their previous seven outings - a 3-2 reversal against Bristol Rovers at the Memorial Stadium - a sequence that has moved them to within just two points of seventh placed Exeter City.
And the former Doncaster Rovers defender has insisted that the lads must continue their impressive form in order to hunt down the promotion pack.
"It's going well," he said about life under the new manager after the 2-0 win against Port Vale.
"We are moving up the table slowly but surely, but because of our poor start we are still playing catch up.
"We believe we are one of, if not the best team in the league and at the minute, we're showing we can mix it with the teams at the top of this league. But we've got to keeping showing it and move up the table.
"The way we are playing at the minute, we want to take that into our home form and make the Proact a fortress.
"We've got a really good squad," he added.
"You look at our bench tonight and we've got quality all over the field. Jay has come in and done really well and the few players who have dropped out of the team will be wanting to prove themselves and get back in.
"We've got a strong squad and we're going to need it if we are to get up that table."
The 25-year-old has been an integral part of a new-look back-line under the Liverpudlian, which has seen drew Talbot revert to right-back, Jamaican international Nathan Smith return from injury at left-back and Hull City loanee Liam Cooper accompany him at the heart of the defence.
Hirdy marshalled the back four to their second successive clean sheet in League Two and their sixth shutout on the road of the campaign, as 21-goal striker Tom Pope and the basement division's top goal scorers had no answer to the Spireites' resolute defence.
"We are happy," he revealed.
"Obviously to come away from a place like this with all three points is a great result and it just keeps our momentum going.
"It was a good performance all round. We looked good going forward, we were solid at the back and we saw the game out well.
"Obviously the first goal, we saw it out till half-time. Then they started to put a bit of pressure on and we were soaking it up as a back-four whilst at the same time looking dangerous going forward and when we got the second goal, that killed them off.
"It was a bit like Plymouth, they had a lot of pressure on us without actually creating much but we defended well against them and tonight against Port Vale.
"Coops [Liam Cooper] has been good for us, he's a solid centre-back and the last three or four games as a back-four, we're getting some sort of understanding and that is starting to show,' he added.
"I thought Marc [Richards] was different class tonight too. He's sharp now and you can see he is getting back to where he wants to be after his injury."
