AUDIO: Stormers' secrets exposed in Sharks campSHARE
Du Preez, who spent his youth career in Durban before moving to Cape Town to play for Western Province and the Stormers between 2014 and 2017, made the move back to Durban ahead of this season's Super Rugby tournament.
Du Preez was the star of the show when Province beat the Sharks in last year's Currie Cup Final and he will still have fresh knowledge of the inner workings of the Stormers ahead of Saturday's clash.
"I do hope that he [Du Preez] will give us a couple of pointers that we probably wouldn't have been able to pick up from the analysis we do," said Sharks loose forward Philip van der Walt.
"I must be honest, we are so thorough in preparing and watching all their [Stormers] games, I doubt that there will be something that we haven't seen, but that is the interesting part about rugby. You come up with new plans and new ideas and I think that is also where we might have slipped over the weekend [against the Bulls].
"The Bulls presented some plays and played a little bit different from what we expected from the previous games that they played.
"He [Du Preez] will definitely give us some insight, but you have to be wary of what they [Stormers] change."
The spotlight will again be on the Sharks' pack in the match against the Stormers. The Durban side were dominated up front against the Bulls in their 10-40 loss last week.
The Sharks were also outplayed in that facet of the game in last year's Currie Cup Final against Province, which is still fresh in the Sharks' memory bank.
"I think the only place where it is really on the mind is the fact that it was such a bitter pill to swallow. It was the Currie Cup Final, they were really good at scrum time, we struggled, and we want to rectify that.
"We know what is coming, especially after our performance against the Bulls pack. We as forwards know we didn't match up to the Bulls forwards, so I think the Stormers will also feel that with the confidence they had in that Currie Cup Final they can come and scrum us and drive us and we just have to front up.
"It is pretty much an attitude thing and we are working on the technical side of it," Van der Walt added.
