MARTY Moore believes Ireland can expose a perceived indiscipline in England's scrum by sticking to their own whiter-than-white principles in tomorrow's pivotal RBS 6 Nations showdown.
Tighthead prop Moore hailed Ireland as among the most disciplined sides in the Six Nations, ahead of the Aviva Stadium Grand Slam eliminator.
World Rugby's professional referees' manager Joel Jutge has warned the Six Nations teams to expect a scrum clampdown this weekend.
Ireland's replacement tighthead believes Joe Schmidt's squeaky-clean side - the least-penalised team en route to the 2014 Six Nations title - can thrive under greater scrutiny.
Moore (below) said Ireland will not directly seek to wind up combustible England front-rowers Joe Marler and Dylan Hartley, but will instead aim to provide stark contrast through toeing the disciplinary line.
"Last year we were the most disciplined side in the tournament and this year we are on track for that again," said Moore.
"It is something we really focus on - we don't want to give anything away for free.
"If we can put the pressure on at the set-piece and generally through our play, we know that maybe something might happen.
"Their discipline might go but we need to be on top in that area.
"If we stay clean, whatever else happens, happens.
"But we know if we stay clean we are in a good position to get the points on the board."
Northampton hooker Hartley has pushed his disciplinary leeway with England boss Stuart
Lancaster to the limit on a number of occasions over the years.
The fiery New Zealand-born forward put his Test career in jeopardy after a three-week ban for elbowing Leicester's Matt Smith off the ball in December.
Hartley's latest suspension took his career bans tally to 50 weeks, with previous offences for biting, gouging, punching and swearing all on a lengthy rap sheet.
England have since mounted staunch defences of their frontline hooker, and Hartley has impressed in the Six Nations victories over Wales and Italy.
Harlequins prop Marler has a history of hot-headed on-field behaviour, but in recent times has curbed that behaviour.
Moore said sledging or general chat between teams in the midst of battle tends to have little bearing on Test proceedings, but admitted Ireland will be ready to keep England quiet tomorrow.
"Some players do talk but hopefully we can quieten them down at the weekend.
"If we just focus on our own discipline we will be okay going into it."
