Mako Vunipola, England, 21, uncapped: Promoted to the England senior team after impressive performances for the U18s and U20s, the Saracens’ loosehead will start on the bench against Fiji. New Zealand-born but with Tongan heritage (father, grandfather and six uncles all played for Tonga) Vunipola grew up in Wales after his father moved their to play for Pontypool. Graham Rowntree has said of him: “He’s a dynamic ball carrier but loves a scrum.”
