Cape Town - The Springboks are wary of the unpredictability of the French as they prepare for their Test at the Stade de France in Paris on Saturday.France are renowned for their unpredictability and can go from being awful the one day to sublime the next.Fullback Willie le Roux, who had a stellar game against Scotland last weekend, said only a win on Saturday would make their end-of-year tour a success. The Boks beat Wales 24-15 in their first game in Cardiff before thumping Scotland 28-0 in Edinburgh."We can expect anything and they sometimes run from everywhere. We'll just have to be wide awake," Le Roux told Die Burger's website.No 8 Duane Vermeulen expects a tough physical battle but also talked about the unpredictability of the French."No-one knows what to expect from them. We'll adapt to their playing style and stick to our structures. Hopefully that will be enough," he said.Wing JP Pietersen, who scored a try in his 50th Test last week, said the fact that there are a few French-based players in the Bok camp could be beneficial."You never know what to expect from the French, but we have guys that play in France who can give us a few pointers on how they play. The French love to play with flair and we can really expect anything."South Africa last beat France in France in 1997 - when Nick Mallett's charges triumphed 52-10 at the Parc des Princes.However, in four visits since - 2001, 2002, 2005 and 2009 - the Boks have come unstuck in the French capital.Kick-off is at 22:00 (SA time) on Saturday.
