WHEN Donncha O'Callaghan reveals that Munster have an exhaustive archive of 80 lineout calls, you can understand just why Tony McGahan's side are not keen to expend unnecessary energy on midweek trash talking.
Now that Paul O'Connell has been ruled out of action following yesterday's suspension, there will be an understandable sense of bitterness between these sides -- and O'Callaghan admits that his side must retain their unswerving focus on the job in hand.
"The thing about these games is that there is a carryover, there are probably things that are said and done in matches that if you played maybe in four months time would be forgotten about," O'Callaghan admitted. "If it's fresh in your mind then it always builds and leaves a bit of a taste. I'm sure they're thinking the exact same thing; it's probably what makes this round of the Heineken Cup special.
"There is the little bit of edge to it, the afters from last week and, it's true, it really is only half-time after 80 minutes at home and now we have to go away.
"It's time to refocus to see what we can get.
"We have to pick up a result away at some stage and this is it, backs-to-the-wall stuff, we have to get a result.
"I don't want to play it out in any other way other than doing our talking on the pitch on Saturday."
O'Connell will once more revert to a role as a back-up analyst, indulging his oft-stated passion for deconstructing the lineout, an area where both sides would feel they may possess an advantage tomorrow.
"We have two guys who are fairly crazy about the line-outs, Mick O'Driscoll and Paulie," O'Callaghan revealed.
"They'll go through to see if anything needs to be fixed, or things that might have been picked up by the cameras, but the calls will all be changed.
"We go through a lot of lineout plays, you could have a library of lineouts with about 80 calls and the lads will pick the ones they feel will be right for this one.
"That's what the two boys do very well."
