Gary Caldwell says it will take time for his side to hit their full stride in League Two, but admits there is an urgency at the Proact.
Chesterfield have lost both their opening games, going down 3-1 and 4-1 to Grimsby and Sheffield Wednesday respectively.
For the manager, minor errors have played a big part in the defeats and once the players cut them out, victories will follow.
“We are not going to be judged on (the Owls) game, we’ll be judged on a League Two season.
“We just have to eradicate small mistakes and if we do that I’m sure we’ll get on winning ways very soon.
“I fully believe in this group of players and I look forward to Saturday.”
Caldwell urges patience, but admits it willb e in short supply in certain quarters.
“I think other people judge all the time,” he said.
“At Wigan it wasn’t until November that our form really became regular winning form and after Christmas we went on a 22-game unbeaten run. It does take time.
“We’ve spoken as a group and said it has to happen quickly.”
