The last time the Crusaders won in Sydney was 2012.
Both the Waratahs and the Crusaders have had slow first halves this season banking in on come from behind wins.
Crusaders assistants forward coach Jason Ryan said "We know we can finish games but we've just got to be consistent right through our whole 80 minutes,"
On paper, the Crusaders are stronger than the New South Wales Warratahs. That's even without Israel Dagg and Seta Tamanivalu, who are out with injuries.
Ryan said the boys will be successful if they work on the negatives they picked up from last weekends game against the Western Force.
"We've got a lot of parts of our game that we're not happy with that we need to grow and obviously sorting our scrum out is one focus this week" he said.
The Warratahs have their own injury concerns with Bernard Foley out due to post-concussion symptoms. He makes way for 21-year-old Mack Mason.
The Sunday game kicks off at 6.05pm (NZ time).
