Gertjan Verbeek says a win over bitter rivals Melbourne Victory would serve as a massive confidence booster for his players following a barren spell.
Adelaide have suffered four defeats in succession following a 3-0 loss to Perth Glory last weekend and are desperate to secure three points.
Verbeek said in order to get back on track, his side must continue believing in the philosophy the Dutchman is trying to implement and be resolute defensively.
“To stick to the plan we have for already six or seven months now,” the 57-year-old told reporters at the pre-match press conference.
“We still have to improve. Sometimes it’s good, sometimes it’s not so good.
“In defence we make too many mistakes and then it’s difficult to win games.
“The best example of course is the game here against Victory at home at the beginning of the season.
“We can do it, but every time we have to challenge that to get to that level and then we have a chance to win.”
Meanwhile, Victory have a new interim coach in Carlos Salvachua following the departure of Marco Kurz.
The visitors succumbed to a 3-2 loss to Central Coast Mariners last time out to remain level on 15 points with the Reds.

Adelaide will be buoyed by the return of German midfielder, Mirko Boland, who becomes available for selection for the first time this season.
Verbeek said his return from injury increases the competition in the squad.
“Mirko (Boland) is one of the experienced players and before he got injured he was a starter,” he said.
“Of course, we get James into the squad and also Louis got his chance and is doing well.
“So it will be hard for him to come back, but it’s good for everyone that you’ve competition.
“They’ve to feel the pressure that there is someone who’s willing to play and also can play there on that position.
“And the best one is playing, I don’t look to names or ages. I look to quality.”
The former AZ Alkmaar boss suggested a win would help restore a sense of belief around all stakeholders invested in the Club.
“When you get to talk about confidence, confidence with players, that’s the first place,” he continued, when asked about the importance of registering a victory.
“But also confidence with the fans, confidence with the board you only get it back with a good win, that’s what you need.”
