Manager Paul Sturrock has warned against taking non-leaguers Stockport County lightly on Saturday.
The Blue Square Bet Premier side visit Roots Hall in the first round of the FA Cup this weekend.
And Sturrock believes the Hatters will prove difficult opponents after scoring eight goals in their last two fixtures.
“Stockport are free scoring at the moment with a decent manager so they will be a hard nut to crack,” he told the official website.
“They have scored eight goals in their last two games so if you don’t give them the respect they deserve then this game could bite you on the bum.
“I was rather it were a league game on Saturday as I would like to get kick started but cups are financially important.
“We want to be in the next round but it is a difficult game.
“But at the end of the day I am very confident we will get the goals we need to progress.”
Sturrock’s first game in charge in 2010 saw Stockport County visit Roots Hall in League Two.
George Donnelly handed the visitors the lead in the 83rd minute before Paul’s son Blair rescued his father from defeat in stoppage time to secure a 1-1 draw.
“It was my first game in charge and we drew 1-1 with an equaliser in injury time,” recalled Sturrock.
“Nobody knew each other then but we should have won the game.
“We’d signed a lot of players and it took a season for things to come together.
“Hopefully this time we won’t need to leave it so late.”
Blues will be without on loan top scorer Britt Assombalonga who does not have permission to play in the FA Cup from parent club Watford.
Leyton Orient has confirmed that midfielder Marc Laird is allowed to play whilst Peterborough United has also made Jonson Clarke-Harris available.
“In some respects it is a blow Britt isn’t available but it is also a benefit,” said Sturrock.
“It enables him to be rested for Tuesday night (Bristol Rovers away) which should mean we will see a different Britt.”
Striker Freddy Eastwood is a doubt with a back injury after hurting it getting up from a chair.
But midfielder Michael Timlin could make a return from an ankle problem.
Luke Prosser (glute) and Ryan Leonard (hamstring) have also resumed training today.
