Ireland are not the only side concerned about their lack of discipline in this year's Six Nations so far.
Welsh centre Jamie Roberts has warned that his side cannot afford bouts of poor discipline when they host Declan Kidney's men in two weeks' time.
Wales conceded 15 penalties to Italy's five in Saturday's 24-16 victory, but the Azzurri also missed four shots at goal, and Roberts fears Ireland will not be so profligate. He said: "I was pleased with our performance, but frustrated at times. It was our discipline more than anything which let us down.
"We gave away too many penalties, some of them silly, to put ourselves under pressure.
"We conceded 15, which wasn't clever really. If we do that against Ireland, we are going to be punished because we probably won't win the game."
