Ryan Crotty's return to the midfield will help solidify that area, but the Crusaders have struggled in the face of a fast-advancing and connected defensive wall this season.
"We're confident in our abilities as a forward pack to go out there and dominate this game, and certainly through the set piece," said Crusaders and All Blacks skipper Kieran Read, rested for last weekend's thrashing of the Rebels.
"Most New Zealand derbies have been physical this season and it will probably end up that way again. But we're not going out there to break any rules. There are ways to dominate teams without doing that.
"It feels like a finals week. There's a good hype around the training pitch."
In pushing the Hurricanes close in Wellington a fortnight ago, the Blues may have provided a blueprint for the Crusaders. Tana Umaga's team took advantage of some poor defending to score three tries, and they were dangerous close to the breakdown.
Jerome Kaino's second try in five first-half minutes came when he picked the ball up from the back of a ruck and sprinted in from 35m after the Blues' coaches noticed the home side continually failed to send defenders to that area.
However, the Crusaders will likewise have to be careful about how they attempt to contain first-five Beauden Barrett.
"It's about shutting down space and time for Beaudy," Read said. "He's pretty electrifying, so we have to get bodies around him."
