Notts County boss Shaun Derry said he has been impressed by the way Chesterfield have adapted to League One.
The Magpies visit the Proact Stadium on Saturday with a record of being the division’s meanest defence so far.
Derry’s side overcame fierce rivals Mansfield Town in the JPT earlier this month which set off an unbeaten run.
He said: “I’ve been very impressed with Chesterfield and it shows just how a sustainable amount of time to create what they want it takes for a manager and it breeds success. They’ve been able to improve their squad and all the promoted sides are flying high still and are riding on a top of a crest of a wave.
“We’ve got to take care of what we can affect and we have the best record in the league, that may change, but it’s a local derby and we want to create a good game.
“They are a good team and we are expecting another incredibly hard challenge. I want to keep the unbeaten run going and we will try to win the game, but we can’t win them all.”
The Spireites start has also caught the eye of veteran midfielder Gary Jones.
“Chesterfield have come up and they’ve carried on that momentum,” he said. “We will be going there on Saturday and try to stop that and do something about it. “They are a good footballing side, with some very good players and a young manager. They have started really well, they are scoring goals for fun and we will need to be on our game. We will need to go there full of confidence.”
