Wales assistant coach Robin McBryde is under no illusions of the challenge facing his charges when they take the field against South Africa in the quarter-final on Saturday.
The southern hemisphere giants are known for their hard-nosed approach to the game and McBryde is expecting nothing different this weekend.
McBryde pointed out how well the two-time world champions dealt with the Samoan's physicality during their dominating 46-6 win.
"Their game against Samoa was a brutal encounter regarding the collisions," said McBryde.
"They have an exceptionally strong set-piece. We know what is ahead of us. We are at a stage now where all the hard work was done in our preparations. We are getting battle-hardened now.
"We are getting into a rhythm up front and, hopefully, we can build on our performances so far. We want to be battle-hardened, not battle-weary.
"They have a strong offloading game when they choose to. They do everything at pace. It is about matching them at the gain-line challenge."
Wales won the last encounter between two sides – winning 12-6 at the Millennium Stadium last November – though McBryde is not reading too much into the victory.
"I don't think in the autumn they were at their strongest," he added.
"They are going to be a difficult prospect this weekend. They have strength in depth."
Wales were hot in attack against a 13-man Australia on Saturday, but still failed to get over the whitewash. While McBryde did take some postives from the losing effort, he did not mince his words when asked about the match.
"We have to learn so if we get opportunities, we have to take them," he continued.
"We were left scratching our heads how we lost it in the end. Fair play to Australia. If you can't score a try against a 13-man opposition, possibly you don't deserve to win.
"We have to take some positivity from that game. We can challenge South Africa. We did that in those games last year. We are getting there. If we continue to build on our performances, we will be in a much better place."
