TOKYO (Reuters) - England's Billy Vunipola is perhaps close to fulfilling coach Eddie Jones' prediction that he could become the best number eight in the world but that has not stopped his aunt offering advice as he heads into the Rugby World Cup final.
Vunipola was at his bullocking best in England's semi-final victory against New Zealand last weekend and his head to head with South Africa's Duane Vermeulen is likely to be one of the key duels in Saturday's title match.
