Chesterfield youth team endured a frustrating night after they were beaten by a single goal away at Staveley.
A header in the second half by defender Ross Goodwin was enough for victory as the Spireites struggled to make an impact in the match, with their opponents worthy winners.
The first real chance of the game came for the away side. Striker Bradley Bowland found himself in space after a shot by striker Mark Fereday was deflected into his path, but his header went just wide of the post.
Midway through the first-half Chesterfield boss Dave Bentley was forced into a substitution as Bowland had taken a knock, with Joe Mathers brought on to replace him.
Both teams found it difficult to create chances in the final third of the pitch as the defences were solid. The first half provided very little action in front of goal, which left both sets of strikers frustrated.
The closest the Spireites came to finding the back of the net was through defender Thomas Colton, who managed to find room in the box after midfielder Joshua Scully put in a fine cross for him, but his header cannoned back off the crossbar and out of play and the sides were level at the break.
Bentley made two substitutions at half time, with defender Jamie McNicholas and striker Fabien Johnson brought on to try and add a bit of spark to a stale half.
The Spireites had plenty of the ball but were wasteful in possession and couldn't find a way to break the deadlock as the home team looked organised.
Bentley's team fell behind just past the hour mark, a deep cross wasn't dealt with by the Blues back four and Goodwin rose highest and found the back of the net.
The Spireites couldn't find a way past a stubborn Staveley team who passed the ball well and dealt with any attack by Chesterfield. Despite a late surge, they didn't create enough chances to warrant taking anything from the game and the performance disappointed Bentley.
He said: "It was frustrating tonight, we never really got going, we looked a bit lacklustre and tired.
"People have got to get switched on who ever we are playing against, they have to be at it from the word go."
Bentley's team continue their pre-season preparation on August 1 when they take on Barnsley at Warminster Road.
