That comes on the back of a disappointing 25-43 loss to the Crusaders in their opening game while the Blues will be fuelled to respond to losing to the Chiefs after being up 19-5 at halftime.
But Waratahs prop Harry Johnson-Holmes, (pictured) a product of Newcastle, said the side knew they had a debt to repay to the local fans.
"We had a great trip last time and we weren't able to get the job done when we went there so we've got some favours to pay back to the Novacastrians," he told rugby.com.au.
"I think the Sunwolves had a very good day that day where everything seemed to be sticking for them.
"For us, when things weren't working for us they were able to capitalise and we weren't able to defensively take the ball from them as much as what we would've liked, therefore they kept piling on points as a great attacking side will," he said.
The Waratahs said they were expecting 'organised chaos' from the Blues and Johnson-Holmes, who has transferred from the loosehead propping role to tighthead, was expecting to come under pressure in the scrums.
He was hoping his absence from the Crusaders loss, due to influenza, would mean there wasn't a lot of video for the Blues to watch about his technique.
"I don't think there's a lot of footage for them to check out but I think that could work in my favour if they're under-estimating how we're going to operate as a front row.
"I've been pretty happy with how we've scrummaged in preseason, we had good dominance against the Highlanders and good parity against a pretty strong Reds pack," he said.
Forwards coach Matt Cockbain expected the Blues would be looking to convert the sorts of opportunities they didn't take in their game against the Chiefs.
"They like that ability to counterattack, they can all run and pass the ball very well, they're quite a big side and agile as well, so they like to take you in in that individual one-on-one situation.
"Again for us, it's to play them with a little bit of structure but get into our attack structure as well as we can move them around and hopefully create those opportunities that we did last week," he said.
