Chesterfield have already become a scalp for other teams in League Two.
That is the view of Paul Cook ahead of his side’s trip to Rochdale, following consecutive league wins against Bury and Cheltenham.
The Spireites boss believes the players have earned a reputation for their performances on the pitch so far, but has warned there are still areas they need to improve on.
He said: “We are at our most vulnerable when we are defending set plays at the minute. We’ll watch the DVDs and there are a couple of things we can do.
“Number one on that list is stop giving silly free-kicks away and two, we need to defend them a little better because we got a bit lucky against Bury and a little lucky against Cheltenham.
“In the bigger picture that luck will go against us one day. In no space of time we’ve become a scalp, which is great credit to the players.”
Chesterfield are yet to concede in the league this season and are likely to continue with Sam Hird and Ryan Edwards at central defence.
The Spireites are monitoring the fitness of both Gary Roberts (heel) and Jay O’Shea (hamstring) while Jamie Devitt is serving the last of a suspension picked up while playing for Grimsby Town reserves on April 8.
Ian Evatt remains short on match fitness though will feature in a behind-closed-doors game on Tuesday, as he makes his first steps back into competitive football.
Rochdale are unbeaten in their last seven matches at home and have lost just once at Spotland since Keith Hill returned to manage the club in January. Cook added: “Keith’s a very astute manager who sets his teams up well. We’ll go there again looking for three points.”
