Bok speedster Arendse one of 4 new Test faces with potential to shine at World Cup

The Autumn Nations Series produced some sparkling rugby auguring well for next year's Rugby World Cup in France.

AFP Sport picks out some new faces whose displays suggest they could be major players in the sport's showpiece:
