The Welsh region head to Loftus Versfeld on Friday night knowing a victory could propel them from fifth to as high as second in the table.
Yet South African Van Zyl is under no illusions about the scale of the challenge—particularly against opponents eager to respond after a derby defeat.
"We will have to fight and swing a few shots because I expect the very best of the Bulls, who will be shattered at the way they played last week. I can't envision the same again."

That message has become the central theme of Cardiff’s preparations following the conclusion of the Six Nations.
The Bulls, beaten 32-19 by the Stormers last time out, are renowned for their physical dominance and set-piece strength—qualities Van Zyl expects to be delivered with renewed intensity on home soil.
"The Bulls' culture is that they back themselves in physical games and to dominate the set piece, while they've also got flyers on the outside," he said.

For Van Zyl, the task is not just about matching that power, but embracing the confrontation.
“We will have to fight and swing a few shots because I expect the very best of the Bulls, who will be shattered at the way they played last week. I can't envision the same again."
Cardiff travel to South Africa in a strong position domestically. They are the only Welsh region currently occupying a top-eight place and have collected points from all 12 URC rounds so far—a mark of consistency that has kept them firmly in the play-off race.

However, their form away from home remains a concern. Since May 2024, their only victory outside Wales came against Zebre in Parma, making this tour—also including a clash with the Sharks—potentially decisive in shaping their season.
Van Zyl is keen to keep his squad grounded despite the encouraging league standing.
"We all looking at the log and seeing where we are," said Van Zyl. "That's part of the dynamics but we can't get too carried away."
Instead, the focus remains firmly on the immediate challenge.
“We are just focusing on one game at a time and taking what we can from each opportunity.”
There is, though, a significant boost for Cardiff with the return of experienced back-row forward Taulupe Faletau.
The 35-year-old is named among the replacements after recovering from a calf injury sustained on New Year’s Day, marking his fifth appearance of the URC campaign following another injury-interrupted season.
His presence adds depth and leadership to a squad that otherwise remains unchanged from the side that ended Leinster’s 11-match winning streak earlier this month—a result that underlined Cardiff’s ability to compete with the competition’s elite.
Several Wales internationals are also involved, including Liam Belcher, Ben Thomas, Mason Grady, Sam Wainwright and James Botham, as Cardiff look to carry that momentum into one of the most demanding venues in the competition.
The Bulls, meanwhile, will be bolstered by the return of number eight Cameron Hanekom, back from a long-term hamstring injury. The South African side also boast significant international pedigree, with 12 players named in Rassie Erasmus’ Springboks alignment squad.
History is not on Cardiff’s side either. The Bulls have won all four previous meetings between the teams in the URC, underlining the size of the challenge awaiting them in Pretoria.
