Wayne Pivac can understand the reasons behind South Africa naming an almost entirely new team to face Wales in their second Test but says his side will not take the second-string Springboks lightly.
Reigning world champions South Africa beat Wales 32-29 last weekend in Pretoria with the final kick of the ball in a thrilling start to the three-Test series.
The sides reconvene in Bloemfontein on Saturday in a game Wales, who have now lost three in a row against their opponents, must win to keep their hopes of a series triumph alive.
The hosts surprisingly named 14 changes to their side for this weekend's showdown when announcing their squad on Tuesday, with experienced lock Eben Etzebeth – in line for his 99th cap – the only player to retain his place in the XV.
Among the fresh faces in the Springboks' side are uncapped pair Kurt-Lee Arendse and Evan Roos, while four others – Ntuthuko Mchunu, Ruan Nortje, Deon Fourie and Grant Williams – could make their debuts from the bench.
Welsh rugby great Gareth Edwards accused South Africa of "disrespecting" Wales with their selection, but Pivac was more understanding when asked about the mass changes at his news conference on Thursday.
"From our point of view, it's a big focus on what we can improve from the last Test match," he said. "We are in a different part of the cycle; really we're at the end of our season, and they're at the start of theirs.
"They've got their reasoning why they did it. They've got depth and quality throughout the squad and some experience in this team. So we're certainly not taking them lightly at all.
"There are players playing there with an opportunity to impress for the third test, so we know they'll come out strongly and represent their country like anyone else in that jersey. So for us, it's around what we can control and that's our performance.
"It hasn't changed our preparation at all. It is going to be 15 rugby players in green shirts, and we are expecting more of the same."
Unlike their opponents, Wales have stuck largely with the same group that came agonisingly close to pulling off a big result last weekend, with wing Alex Cuthbert replacing Josh Adams in the only change.
Adams is among the replacements, as is uncapped prop Sam Wainwright after Tomas Francis returned home following the concussion suffered in the first Test.
Elsewhere, George North will equal Stephen Jones' record as the most-capped Wales men's international back when making his 104th appearance.
Pivac's side head into the contest on a run of four successive defeats, each coming by a margin of four points or fewer – not since a six-match losing streak between February and November 2020 have they endured a worse run.
