The Jaguares impressed all season to finish on top of a tightly contested South African conference and showed they were more than capable of getting the job done at home or on the road.
"There aren't many guys who would have said you'd be playing them [in the final] at the start of the season. You've got to give it to them. You've got the ability to front up when they do travel," Robertson said of the Jaguares.
"We're really impressed with them. It's going to take all of, probably more, effort than against the Hurricanes."
Robertson described last weekend's semifinal against the Hurricanes as "anything but a final", with the high-intensity affair going down to the wire.
The side will be without star duo Ryan Crotty and Scott Barrett for the final, with Ennor replacing Crotty in the midfield and Mitchell Dunshea deputising for Barrett at lock alongside Sam Whitelock. Young outside back Will Jordan joins the bench.
