"Out of all the South African sides the Cheetahs probably play a style that is closest to ours. They are innovative and can score tries from anywhere around the park and like all South African sides they are big and physical," said Rennie.
"We had a really free-flowing match against them in Bloemfontein last year, and we are expecting them to play a style of game similar to us, which is a high-paced, ruck and run game."
Rennie was impressed with his young players on debut against the Highlanders last week, particularly hooker Marshall, who has yet to play an ITM Cup game. He put in a solid 70 minute performance covering for Elliot and injured Mo Schwalger.
Another debutant, Bundee Aki, was strong and showed in conjunction with Aaron Cruden that they were able to limit the space around the Highlanders' Ma'a Nonu. The final new cap, Patrick Osborne, scored a crucial try at a crucial stage in the match.
"Considering the amount of injuries we had, the whole team really stood up," said Rennie.
"It was a real lift in intensity from our pre-season campaign and to get five points down in Dunedin and deny the Highlanders any, was a great start."
The Chiefs Player of the Day was Tim Nanai-Williams, who was extremely ill on game day.
Chiefs coach Wayne Smith asked him to see if he could manage to play for 20 minutes, but the gusty stand-in centre managed 65 minutes before nearly fainting after his second try.
His superb break and step to fool All Blacks fullback Ben Smith for his first try will long live in the memory and is an early candidate for try of the season.
