MunsterWith the international players restored and captain Jim Williams back from injury, the Munster team for the game against Neath on Saturday at The Courage Gnoll, shows 10 changes from the one beaten by Ulster last Friday.
Denis Leamy and Colm McMahon were both unlucky to lose out.
Leamy has performed well for Munster in the two games he's played, while McMahon has been equally as impressive coming off the bench.
"We've picked the strongest possible side for what will be a very difficult game," said coach Alan Gaffney.
"They need to win this one and if last year's game is anything to go by, then we are in for a very tough game.
"This game will provide very useful preparation for us for the European Cup game against Gloucester the following week, but first and foremost it's a game we need to win to secure our place in the quarter-final.
"Having a near enough full squad to choose from is good. They're all quality players and fit in well, but it takes a little time to get certain things right. The selection itself was difficult."
MUNSTER (v Neath): J Staunton; J Kelly, M Mullins, R Hendeson, M Lawlor; R O'Gara, P Stringer; M Horan, F Sheahan, J Hayes; D O'Callaghan, M O'Driscoll; J Williams capt, A Quinlan, A Foley. Replacements: S Kerr, J Blaney, M Galwey, E Halvey, D Leamy, M Prendergast, D Malone, J Holland, D Crotty.
