Chiefs head coach Dave Rennie has admitted the side will have to sharpen up their scrum before heading to Argentina.
A dominant display upfront by the Lions proved to be a major factor in their first ever win over the Chiefs in Hamilton on Saturday.
Rennie knows the Chiefs have work to do in that area in order to be competitive for their next two matches away from home against the Kings and Jaguares.
"Our set-piece is going to have to be pretty sharp because there's no doubt another African side will see that as an opportunity to target us," Rennie told the NZ Herald.
"And no doubt the Jaguares will think the same. They have a massive scrum and will try challenge us there, too."
Rennie added that he wasn't entirely convinced by some of the interpretations made by referee Andrew Lees at the scrum, whilst knowing that it was the Chiefs' responsibility to adapt.
He explained: "You're always going to argue around scrums. We just have to do a better job of defending that and painting a picture.
"We're not trying to blame the referee for our issues. Our issues were our own. At scrum-time, we know we're going to be targeted so we have to do a better job."
