The Chilli Boys and the Clever Boys will battle for a semifinal spot at Bidvest Stadium at 20h15, and Larsen believes the home team are the ones who are under pressure to progress.
"I expect Wits to put out their strongest possible team. As underdogs we have nothing to lose so we will have a full go at trying to cause any upset.
"As a team we are in a good space having only lost twice in nine games, and those two losses should have been wins against SuperSport [United] and [Black] Leopards respectively.
"We've had a great week of training and are looking forward to this match."
