Crusaders coach Todd Blackadder was left disappointed with his side's attack following their 25-19 victory over the Melbourne Rebels on Friday.
While being pleased with the defence shown at AAMI Park, just one try was scored by the New Zealand outfit as hooker Ben Funnell went over.
And that led to Blackadder explaining in the post-match press conference that there is still plenty of work to be done during the upcoming bye week.
"Off the back of not having a potent attack tonight we defended with our hearts and it probably made the difference in the end," he said afterwards.
"We can go into the bye next weekend in pretty good nick and we need to put a lot of work into our attack and there are a few things we can do which will certainly improve our game."
Meanwhile, Rebels coach Tony McGahan said the Crusaders' experience got the better of his team.
"They were just a bit cuter than us in certain aspects and they controlled things really well," he said.
"We kept coming back and they kept slipping away."
