The Cape side have been employing an aggressive defence like the New Zealand sides and say the tactic will work fine in the derby test.
Skills coach Paul Feeney says: “The sharks play a different defence to the New Zealand teams and attack.
“They are playing well and have confidence and have won more games than us this year.
“So we have to be on top of our game to come out on top in Durban.
“I think the Sharks are a good side, we’re not taking them lightly or guessing about the intensity of the conferences.”
