"We can just look at last year and learn a lot of lessons from that," he said of last year. "We obviously slipped up in the last game. I know the boys are going to be really eager and excited about this. We just have to make sure we do everything right ... it's a little different this week too, being on a Sunday [Monday NZT] - we have an extra day to recover which we're going to have to use wisely."
Cruden, showing the same cool head he displayed on the Twickenham pitch as the home side mounted an impressive comeback to take the lead at 22-20 after being down 17-3, said going through a calendar year unbeaten for the first time was more of a media construct than something driven from within.
"The media will make a bit of that this week and we're obviously aware of it - it will be a massive achievement - but the focus first and foremost is getting everything right for a good performance.
"We've been together a long time now ... it is a little bit mental, but the exciting thing is the boys are aware that it's the last game so that will energise us through the last week because we know we've got nothing after the game. The boys will be pretty excited about that and I'm sure there will be a few laughs and a lot of excitement during the week."
Cruden was tidy as usual when he replaced Carter. He missed one penalty from a handy angle but was on target with his other kicks and scrambled well on defence. He packs a lot of power into his relatively small frame and his leg drive when going into contact was noticeable. He is becoming a bit of a charge-down expert too and notched another yesterday to keep the pressure on.
"I was on a little bit earlier than I was going to be but I love the challenge. The game was in the balance there and the way the boys were able to hang in the fight, especially in that second half ... and storm home was great."
