"There's a lot of things to talk about but we won't be talking about the fact it's difficult to fly over [to South Africa] and fly straight back and perform well. We haven't got an option, so we'll talk positively about what we need to do and hopefully we'll be fizzing on Saturday."
That mood will need to be attained despite another abbreviated week of preparation, with the Chiefs set to arrive back in Hamilton early tomorrow morning.
While the Crusaders will spend the week leading up to the semifinal enjoying the luxury of sleeping in their own beds, their opponents will be focused on merely syncing their sleeping patterns appropriately.
And the challenge, as evidenced by the teams' respective quarter-final victories, extends well beyond the bedroom. While the Chiefs struggled to get their game going and had to rely on an outstanding defensive effort in Cape Town, the Crusaders were completely ascendant in trying conditions in Christchurch.
There will be plenty of pressure on a visiting pack led by Brodie Retallick to match their illustrious foes, but Rennie was keen to focus on his own unit rather than the home side's.
"Obviously we've got a huge amount of respect for the Crusaders - I thought their pack was incredibly dominant again," he said. "That's going to be a challenge for us, but we've got a pretty good pack.
"We're excited. It's down to four teams now - that's where we want to be."
