England number eight Billy Vunipola has responded to South Africa’s promise of all-out aggression in Saturday’s World Cup final by declaring “bring it on”.

Springbok lock Lood De Jager stated after Wales were edged 19-16 by a dominant forward display that “the only way we know is fighting fire with fire”, setting the scene for a titanic battle up-front against Eddie Jones’ side.

England’s pack has been equally forceful and Vunipola is relishing the opportunity to trade blows at International Stadium Yokohama.

Vunipola will resume his personal duel with South Africa back row Duane Vermeulen who made a major impact on his return to Test rugby during last summer’s 2-1 series victory over England.

“I’ve played against them a few times and he’s got up the last few times so personally I’m going to try my best to win that little battle so to speak and hopefully that will help the team,” Vunipola said.

“I played against him last summer and he was monumental in terms of getting them those two victories.”
