Manager John Sheridan knows it will be a tough game away to league leaders Burton Albion but admits his side will take the game to their opponents.
The Brewers, who gained promotion from Sky Bet League Two last season, are exceeding all expectations in Sky Bet League One this season.
They have occupied top spot for a large part of the season, despite a change in manager half way through the season.
Speaking in his pre-match press conference, Sheridan said: “It’s going to be a really tough game.
“They are flying at the moment and credit to Nigel, who took over from Jimmy Floyd Hasselbaink who did a great job there before he moved on.
"Nigel has taken over and they are playing with a lot of confidence. They are very organised and have one or two decent players but they are playing with consistency and each player knows their jobs.
"They work very well as a team and are hard to play against. They score goals, keep clean sheets and win games so credit to them.
“They will be confident as it’s a game against a team who are in the relegation zone but Nigel knows me and he knows he will get a tough game.
“We have got to go believing we can get something from the game and with it being on TV, it will be a good attraction but we know we are going to have to go there and scrap for every ball but I believe we can do that and we have shown that with recent performances."
The game will be broadcast live on Sky Sports (12.30pm kick off) but the manager believes that will not make a difference to either side.
“They will want to show why they are top of the league and why they are doing well,” he admitted.
“They will be looking to put in a good performance to show everyone how good they are but we have just got to go there and perform.
“We have usually done well away from home but we know it’s going to be a tough game and if we are not ready for what will get thrown at us then we will get turned over.
"We are working hard during the week to put things right. We have conceded six goals in the last two games and that is not like us.
“We are usually tight but we have conceded soft goals and we need to change that.”
It is a busy couple of days as Chesterfield visit SportsDirect.com Park on Monday in what is going to be a big game and the manager knows the importance of having a good run of form over Easter.
"We have two big games coming up. Easter is a busy period,” he said.
“You could find yourself in a sticky position where we currently are, because we are in the relegation zone, but if you pick one or two good results up, you could gain a little advantage if you get the right results.
"That’s all we’ve got to think of, ourselves. We need to go and think we can win at Burton and then we go on to Chesterfield which is another massive game.”
