Goals from midfield pair Mason Coy and Jordan Walshaw moved the Spireites' youth team to the top of the table in a 2-0 win over Grimsby Town.
Chesterfield went into the break a goal to the good in the match at Staveley Miners Welfare FC's Inkersall Road ground.
The lead was doubled and the points secured with Walshaw's second half strike, but coach Mark Smith felt that had his side been more clinical the score could have been higher.
He said: "I thought we were good value for our victory and we had two well-taken goals. I think we need to be a bit more ruthless at times, but that's what we've said all season, we could have come out with four or five goals.
"We were always better than them and they only had one shot on goal in the game. I think they came here aiming for damage limitation, just hoping not to get beaten by too many.
"We always strive to do things properly and I felt we did that yesterday. There were a couple of times when we could have been more ruthless, but it was a good win."
Now top of the league, Smith feels that the heat is now on his side to keep up their success if they're to finish the season where they want to be.
"We're there to be shot at now," continued Smith. "We've worked hard to get there because we've been three or four games behind people and we talked about having to win those games, which creates pressure in itself.
"Now we've achieved that and there are two ways it's going to go. We could think we've done our job by getting to the top - but we've still got another five or ten games where we now need to stay at the top.
"That has it's own pressure, and people will turn up with the extra incentive of trying to beat the side top of the league."
The youth team have now put together a run of eight successive league victories, but Smith knows that things won't be getting any easier with even tougher games on the horizon.
"We've been fortunate, the teams we've beaten to get to the top of the table are ones we'd be hoping to beat, but now in the next run of games we've got Notts County, Hull City and Doncaster Rovers, and they'll be strong.
"We've lost to two of those sides already this year so this next batch of games will tell us a lot about our group of players and now what we need to do is go out and beat the next level."
