Walker also said the United defence will have to be wary of frenchman Raphael Berthelot who scored two goals off the bench when the two clubs met previously - including the winning strike.
"He had the sort of quality that can pull a goal from anywhere so we need to try and mark him out of the game," he said.
United will be at full strength and look to in-form strikers Ash Gower-Rudman and George Watson to be in clinical form in front of goal.
The home side come into the game on the back of last weekend's 4-1 local derby loss to the only unbeaten Premiership team - rivals Ngongotaha AFC.
Despite the loss Walker said the team were feeling very confident after playing with "attacking menace".
"In the past it's been said that we park the bus so to speak," he said. "But this wasn't the case against Ngongotaha. We really went for them and can take a lot of belief from that.
"We just needed to be a bit more clinical in front of goal.
"On our day we can beat anyone and Ash and George look like a dangerous threat up front."
Elsewhere, top of the table Ngongotaha are aiming to record their fourteenth win of the season when they take on fourth placed Otumoetai away tomorrow.
