WP will be hoping to take another step towards an Absa Currie Cup home semi-final against a Griquas team who would be hell-bend on keeping their faint chance of qualifying alive with a victory.
De Villiers, who just recently returned to WP after a stint overseas, said the WP backline players are still getting accustomed to each other. And he warned that Griquas should not be underestimated.
"I think they've shown in the competition that they're one of the top sides. It's been a much tougher competition this year with Griquas being so strong, and the fact that there are six teams that can still make the playoffs is very good for the competition.
"They're strong in all facets of the game and where as in the past they've struggled with depth, they've managed to fill the positions this year when they've had injuries.
"Obviously they do rely a lot on Naas Olivier at 10, Riaan Viljoen at 15 and a guy like Bjorn Basson who is a fantastic player.
"As a backline they've scored some good tries and they'll definitely be testing us on defence, but we're growing as a backline and hopefully we can keep on improving this weekend going into the next phase of the competition."
The Bok centre said it was important for the forwards to provide good, front foot ball so the backline can test defences a bit more. "It all starts with the platform that the forwards set for us and as backs we managed to put a couple of good phases together (against the Pumas) but there were opportunities to score three or four more tries and we didn't.
"In tighter games we will only get three or four opportunities and we have to take those. It still was not a 100 percent performance and there's still a lot to improve on but if we can keep on improving as a backline and as a team then hopefully we will advance to the playoffs and secure a place in the final."
De Villiers emphasised that the Province team at this stage was not thinking about bonus points. "If we win all the rest of our games we'll win the Currie Cup, it's as easy as that.
"We're not thinking about bonus points; we're thinking about the process of how to get to win. The focus is the next challenge at hand and that's Griquas. Come Friday night, the first kick-off will be our next focus.
"Yes the table is congested, but the Sharks have got quite a good lead on us and we've got a 5-point bumper on the Bulls, and I think we'd be stupid to focus on that.
"We need to focus on the Griquas, get a good result and then come Monday focus on the next challenge."
