Juan Martin Hernandez (Argentina)
Once again, Argentina will arrive at the Rugby World Cup billed as a country most capable of upsetting the establishment.
Drawn alongside France and Ireland in Pool D, don't be surprised if the Pumas finish top.
In Stade Francais star Hernandez, Argentina boasts a player of exceptional quality, a fullback with an attacking game so effective it complements superbly the creative quality of halfbacks Felipe Contepomi and Agustin Pichot.
Hernandez though, is also a rock-solid defender, as he underlined when stopping Leicester's Samoan juggernaut Alesana Tuilagi in his tracks during a Heineken Cup clash between Tigers and Stade last season.
