Clarke's Saddlers haven’t won since their opening day triumph over Northampton Town - drawing two and losing three of their five subsequent league outings - and will be looking to rectify that when they travel to Essex tomorrow.
Clarke, who saw his side lose an EFL Trophy bonus point penalty shoot-out to Coventry City in midweek, admitted that a lack of confidence may have crept in but he is keen to see his side prove they are mentally strong as they look to quickly return to winning ways.
Speaking via the club's official website, Darrell said; "We need results, there’s no papering over that. While appreciating that the lads are knuckling down and getting on with their business.
"Mental strength is very important in this situations where a lack of confidence can come into the players’ minds and you need to beat that out of them straight away and focus on the next game.
"My coaching staff and I need to get the plan and preparation spot on and go and try and pick up three points on Saturday."
The Mansfield-born boss went on to insist that he is confident in both the squad and himself that they can turn results around. The gaffer believes he has a wide range of experience to draw back on and won't allow his side to cry over spilt milk.
Darrell added; "The focus has to be on performances but you don’t get anywhere feeling sorry for yourselves.
"You pick your heads up, stick your chest out and you take your flack, take your stick and you rebuild. A lot of that focuses on the mind that they’re mentality prepared and not fearing failure.
"I’ve been a manager that’s lost one game in 39, I’ve been a manager that’s been on losing runs, I’ve got promotion, I took over eight games of a team that got relegated so I think those experiences put me in a good stead to manage how I feel fit to manage these situations.
"If you look at my staff as well, we’ve got ex-Premier League players in Marcus Stewart and Maik Taylor and it’s making sure that they keep the positivity around the place and building our siege mentality."
