15. Simon Zebo (Munster)
The Cork speed demon thrived in the open spaces at Thomond and his opportunistic finishes for both tries oozed class.
14. Fergus McFadden (Leinster)
The Suncroft man showed his sharpness to dive over for a try after just 90 seconds and was strong in defence.
13. Darren Cave (Ulster)
A coin-toss between Cave and Luke Fitzgerald but the Ulster man's hat-trick tipped the scales in his favour.
12. Ivan Dineen (Munster)
Came in for Denis Hurley after just 22 minutes and thrived in a position where Munster have struggled this year. Seemed to be able to break the gainline at will.
11. Andrew Conway (Munster)
A great finisher and his two-try haul shows just how important he will be for the remainder of the season for Munster.
10. Jack Carty (Connacht)
Carty was the catalyst for a terrific Connacht comeback in La Rochelle. Is continuing to improve under Pat Lam.
9. Kieran Marmion (Connacht)
With Eoin Reddan and Conor Murray doubts for Ireland's Six Nations opener with Italy. Marmion put his hand up with another impressive display.
8. Roger Wilson (Ulster)
Wilson made a bone-crunching 18 tackles in a brilliant defensive display for Neil Doak's side.
7. Jordi Murphy (Leinster)
Not the biggest openside in the world but he is a willing ball carrier and has a knack for picking the right lines of running. Tommy O'Donnell unlucky to miss out.
6. Iain Henderson (Ulster)
Didn't look like a player who was making his first appearance of the season. Ulster have been crying out for his huge physical presence and Joe Schmidt will be keeping a close eye.
5. Paul O'Connell (Munster)
The Limerick colossus did have a few errors but his relentless ferocity gets the best out of those around him.
4. Franco van der Merwe (Ulster)
Used all of his bulk to get effect at the breakdown. A very important player for Ulster of they are to make the Pro12 playoffs.
3. Marty Moore (Leinster)
Moore had a tough encounter against Matt Mullan but more than matched the England international.
2. Rory Best (Ulster)
A few issues at the lineout but his dynamism at the breakdown and leadership qualities make him one of the best hookers in the game.
1. James Cronin (Munster)
A costly knock-on just before the break was the only blot on an otherwise fantastic display from Cronin.
