HALFBACKS:
- Fly-half. Owen Farrell (England)
- Scrum-half. Conor Murray (Ireland)
Verdict: Would be a major shock if either were left out
FRONT-ROW:
- Loosehead-prop: Mako Vunipola (England)
- Hooker: Jamie George (England)
- Tighthead-prop: Tadhg Furlong (Ireland)
Verdict: Furlong is an absolute certainty, but George and Vunipola will be relying on past exploits to be named in the squad
