Bulls captain Pierre Spies says the Bulls have little interest in winning the South African Conference winners trophy which was won by the Stormers last year.
The new Super Rugby draw divides the fifteen teams into geographical conferences and the winner of each conference is awarded a trophy.
The Stormers broke their trophy drought last season by winning the South African conference as they finished the regular season as the top South African team.
"The reason you want to finish on top in this series is to win the real thing," Spies told Beeld newspaper.
Spies said that he believes that the regular season should be used to play for a home semi-final and final and not for a trophy.
"That other cup (trophy) isn't very high on our agenda and I don't think the other teams' players care that much for it as well."
However Bulls coach Frans Ludeke says that the Stormers recent successes have not gone unnoticed in Pretoria.
"They were the top South African team and we respect that. It spurs us on, but we want to get rid of the emotions for this one."
"It's about the team with the plan."
Ludeke said that the intensity in contact and the battle on the advantage line will be of key importance in Saturday's Super Rugby clash.
"The Stormers defend really well, like they showed against the Lions.
"A good start will help, but we'll have to be accurate for 80 minutes if we want to win."
"The result is all that matters and I'll be happy to win ugly," added Ludeke.
