Phil Brown says Blues have the opportunity to put a marker down against in-form Wigan Athletic on Saturday.
Paul Cook’s side have won their last three and are currently second in the Sky Bet League One table, so will pose tough opposition.
But Brown is expecting a response from his side to the 4-1 defeat to Doncaster last time out when Blues visit the DW Stadium.
“I’ve seen a response in training so far this week, but I’ve always said to the players Monday to Friday is a means to an end. Saturday is the key to it all.
“Having gone four games on the bounce winning them all, rightly so the players are saying there’s not much wrong with the football club, but it’s my responsibility to find out what is wrong.
“We’ve had two occasions, the 5-0 defeat to Rotherham and then obviously at Doncaster on Saturday, when you have them glitches in your season, but you’ve got to go through them.
“The pain barrier is excruciating, it’s awful. The preparation and planning of what’s coming is the most important thing.
“We’ve got back to back games against two sides who are really in form, none more so than the one we face on Saturday.
“It’s a big challenge for us and one where we can put a marker down where this season is concerned and certainly put the Doncaster game behind us. It’s a good opportunity for people.
“Cooky has gone back home as it were from Portsmouth and his teams like to play the right kind of football.
“He’s got Peter Reid alongside him with vast experience. There’s lots of things to admire about them but we’ve got to go there and execute the gameplan and hopefully come away with the spoils.”
