Assistant coach Andrew Goodman said the Reds, who travel to Christchurch for Friday's game, had been close in several of their games.
"They've given themselves plenty of opportunities. They've been right in games until the 60th minute, creating lots of opportunities but they probably haven't finished those opportunities," he said.
"We've seen some real threats out there with [James] O'Connor and the like running good ships so we'll have to be right on."
Goodman said the reasons why the side struggled in the last quarter were varied. But among them was the failure to take opportunities earlier and that allowed opposing sides to get back in the game.
With that in mind, the Crusaders would be looking to take advantage by putting the foot on their throats and keeping them under pressure for 80 minutes.
The Crusaders made the most of the bye week, several players heading out of town while others stayed home and came into team headquarters to train as a group.
"It was a nice, refreshing break, the boys all came back in and had a spring in their step. Everyone's ready to go again," he said.
Also returning to action after injuries are: prop Oli Jager, locks Scott Barrett (pictured) and Quinten Strange, and flanker Billy Harmon, who played for the development side last weekend.
Fullback Will Jordan, who had suffered a groin strain against the Blues, was probably another week away, he said.
"Hopefully they'll get through the week's training and be in contention for selection," he said.
