They warmed up with a 40-24 demolition of Leeds Carnegie at tomorrow's match venue last weekend while Munster were losing to arch rivals Leinster but it could be argued that of the two, Munster had the the better prep game, a claim that finds favour with Munster captain Denis Leamy.
"They (Leinster) are a very good side and putting aside the result and the disappointment of that, I think we couldn't have asked for a better lead-in. Would we have been better off doing what they did, getting a bonus point win at home to the bottom placed side in the Magners? Or having what was a Heineken Cup level game against the side that won the competition two years ago?
"I don't know, others will debate that." He contnues. "We certainly have no illusions going into this one, either about ourselves or London Irish."
Leamy moves to the blindside with James Coughlan at number eight and Tony Buckley back in the front row, while Peter Stringer starts alongside Ronan O'Gara, Johne Murphy moves to full back with Denis Hurley coming onto the wing.
Aligned against them will be the massive Seilala Mapusua, the even bigger Sailosi Tagicakibau, and nimble footed Topsy Ojo, and we're just talking about the backs. The Irish man Bob Casey leads a rugged pack that contains the likes of Clarke Dermody, Declan Danaher and Nick Kennedy, and if Munster are to get anything from this game they need Sammy Tuitupou to carry off where he left Leinster last week, Ronan O'Gara to do what he does best, and introduce just a little more precision into their game than was displayed last weekend.
They also need perhaps to invoke the inspiration of the man that was burried yesterday, Moss Keane, who never took a backwards step and if Munster copy that it will be a good day for them and their supporters in West London.
