Ireland-England combined XV: Which team has the most players included?
Ireland's clash with England at the Aviva Stadium on Sunday is already being viewed as a title decider. Our combined shows that the Ireland backs have the edge over England but the auld enemy dominate the pack.
15. Rob Kearney (Ireland)
Mike Brown could have been close only for his head injury. Rob Kearney has shown plenty of leadership in the victories over Italy and France. He has ran the ball back with purpose and has looked as supreme as ever in the air.
14. Tommy Bowe (Ireland)
Joe Schmidt has utilised his aerial skill to retrieve Sexton's garryowens. He hasn't had much ball through the hand but is doing what is asked of him.
13. Jonathan Joseph (England)
The deserved man-of-the-match from the Italian game and a tryscorer against Wales. Joseph has become an accidental hero for Stuart Lancaster.
12. Robbie Henshaw (Ireland)
Showing subtlety to go with his size, the Connacht centre is fast-becoming a world class centre.
11. Simon Zebo (Ireland)
The Corkman is like a coiled spring on the wing and just edges out Anthony Watson. Zebo's potential shades it for him.
10. Jonathan Sexton (Ireland)
Sexton gave a majestic kicking display on his return from a 12-week lay-off. Undoubtedly the best number 10 in the northern hemisphere and judging by his tactics, Joe Schmidt knows it.
9. Conor Murray (Ireland)
Murray is one of the best box-kickers in the game but has grown in stature over the past 12 months to become a leader in the group.
8. Billy Vunipola (England)
Vunipola is a terror at the breakdown and at the restart. The number of turnovers and penalties that come from his defensive efforts is impressive and the absence of Jamie Heaslip will only help him.
7. Sean O'Brien (Ireland)
The Tullow Tank is back. His clear-out of a French ruck a fortnight ago showed Ireland what they had been missing. His ball-carrying has been sorely missed.
6. James Haskell (England)
It pains me to leave out Peter O'Mahony but the Wasps flanker has been immense. His sheer physicality and size makes him a huge player on Sunday.
5. Paul O'Connell (Ireland)
You run out of adjectives for the 35-year-old Limerick man. A leader of men as well as an amazing rugby player.
4. George Kruis (England)
Has adjusted to life in the Six Nations very quickly. The fact that England are not talking about Joe Launchbury and Courtney Lawes being missing is a huge compliment.
3. Dan Cole (England)
The tighthead doesn't like coming up against Cian Healy but offers more than Mike Ross in a general sense.
2. Dylan Hartley (England)
When he's not in the sin bin or trotting in for a hot shower, Hartley is one of the best hookers in the game and his proficiency from the lineout sees his selected ahead of Rory Best.
1. Joe Marler (England)
The Harlequins prop has been in terrific form and is an expert scrummager. Will pose Ireland a lot of problems.
