The Spireites are down but far from out and defender Sam Hird believes his side are more than capable of tuning their 1-0 deficit aroundnd in the second leg at Deepdale on Sunday.
With Chesterfield putting in a strong performance on their way to their slim loss Hird doesn't feel that there will be any issues with the Spireites losing their confidence.
He said: "I've just been saying with a few lads in there that we've got to keep our heads held high, which we will do because we played well and were just missing that end product.
"At the moment we are playing that well that we fancy ourselves in every game we play in. We've got to go there, play our game and hopefully get a couple of goals to win the tie.
"We do run the risk by playing an open game, our full backs do push forwards. That's the risk we take playing our expansive game, we need to start a bit better on at their place, take the performance we put in during the first leg and go from there."
Hird also suggested that the scoreline and the two clubs' finishing positions in the league table lump all the expectation on the Lilywhites for the second leg - a situation that Chesterfield could be able to exploit on Sunday.
"There's no pressure on us at all, the fans are behind us as they have been all season and I think there'll be a lot of pressure on them at their place, especially if we dominate the ball as we have.
"Now we need to go there, get that first goal and make it interesting."
