Cape Town - The Stormers are bracing for a Test match-sized challenge when they host the Jaguares at Newlands on Friday.
The Stormers are keen for a home win ahead of their tour of New Zealand and Australia, but it will be far from straightforward against a Jaguares side which is a proxy for Argentina's national team.
"They will essentially be an Argentina Test match team so we know what to expect and will be preparing to play Test rugby this weekend," said Springbok centre Damian de Allende, according to reports.
"Fortunately though, and this is not meant to sound arrogant, we have a lot of international players too and we know what international rugby is about," he added.
Stormers coach Robbie Fleck on Thursday made four changes to the Stormers starting line-up.
Forwards Steven Kitshoff, Scarra Ntubeni and Juarno Augustus will all make their first starts of the season, while the only change to the backline sees Dillyn Leyds come in at fullback.
Kick-off is at 19:10 on Friday.
