Chesterfield suffered their first defeat in 10 games on Tuesday night as they went down 2-0 to Morecambe.
The Spireites started brightly but two goals either side of half time were enough for the home side to claim victory.
Speaking ahead of the trip to Aldershot, Tommy Wright revealed that his side must learn from Tuesday's mistakes and start to capitalise when creating chances.
He said: "We've got to learn that we have got to play for 90 minutes; well for more than the 40 minutes where we did play well.
"I've looked at the DVD a couple of times and we got in some great positions, had some great chances but the final ball let us down.
"We were disappointing in the second half and they were the better team, which is disappointing but it's gone and we can't do anything about that now."
Saturday's opponents Aldershot surrendered a 3-0 lead to Torquay on Tuesday night who came back to win 4-3.
Wright believes that the Spireites will face a similar test to that of Morecambe when they face the Shots this weekend.
"It'll probably be similar [the game against Aldershot] to the Morecambe really. We thought they started nervously, I think if we'd have scored first it would have had a massive difference on the game and I think that might be the case on Saturday," Tommy said.
"If we can start well and get the first goal I think that'll be a massive thing in going towards winning the game."
"Everybody was disappointed the other night but coming in today there is not a lot of dispondancy.
"The players trained really well, we're positive, it's only one defeat in 10 and it's a tight league.
"I believe that when we get everybody fit and we bring one or two addtions into the squad we'll be a team that's pushing."
