The Saddlers, who slipped to a narrow defeat at home to Bradford City at the weekend, have won just one of their eight league outings so far this season, and go into their clash with the Shrimps in need of a positive result.
Mansfield-born Clarke has overseen a summer of change at the Banks's Stadium and admits that his almost completely rebuilt team must do much better if they are to avoid this season becoming a carbon copy of the last.
The Saddlers have netted just one goal in their last six league outings and, despite securing four clean-sheets in all-competitions so far this season, have to begin to find form as the fixtures continue to arrive thick and fast.
Speaking via the Express & Star, Darrell said; "At the minute we’re failing miserably, I’m failing miserably, I lead the troops and we have to do a lot, lot, lot better than we have been.
"I know it’s boring and fans will be sick of hearing it but you have to keep working with it and working with the players and changing the mindset of the players in that final third, you keep doing that and eventually it’ll turn.
"You’re not going to score a goal if you’re outside the box, get in the box, commit players into the box, then it has to be a better cross, crossing was poor today.
"Options in and around the box weren’t there, players not taking a shot when they can have a shot, there’s so much work on."
Despite his side's poor start to the season, 41-year-old Clarke is adamant that the tide will turn if and when his recently rebuilt team can begin to put some of their training ground displays into practice on matchdays.
The manager continued; "I’m sick of saying it, five, six weeks we’ve hammered our forward play, we’ve hammered our work and in training the ball is hitting the back of the net but in matches it’s not going anywhere near it, so we’ve got to keep working and drilling it.
"Making sure players don’t lose confidence, making sure that next time we step on the pitch on Tuesday night at Morecambe that we’re ready to go again.
"We’re in a disappointing position at the minute, but let’s see where we go, you can comfortably lose 15 games in this league and still finish in the top half of the table.
"So we’ll be working away, chipping away, and building a football club that I think needs building, that’s why I came in and took the job."
