Simon Zebo (Munster)
Momentum and confidence are crucial to everything in sport and Zebo has bags of both, coming into the spring on the back of a hat-trick against Northampton. There is plenty of jostling for an Ireland wing position, but with his flair, pace and finishing ability, Zebo can put his hand up with a display this evening.
It's a battle between the Ians for the third out-half spot and Keatley would appear to be ahead of Madigan and Humphreys. Madigan can make an impression off the bench, with his maverick skills and pace to burn, but Keatley's game management and kicking accuracy are strings to his bow, and if he dominates this game he can cement his place.
The subject of a tug-of-war between Leinster and Munster, the precocious back-row has a massive reputation but, in a province where he is competing with a host of other internationals for a starting berth, his opportunities have been limited. Declan Kidney is a fan, so a performance against Thomas Waldrom would help his cause.
Not a natural No 7, the Wolfhounds skipper has been doing an impressive job in Ulster's march on the Heineken Cup and, although he missed out on a place in the senior squad, he cannot be far away from Kidney's thoughts.
