Jamie Heaslip believes Ireland are close to producing a special performance - if they reduce their error-count.
Ireland head to Murrayfield for Sunday's showdown with Scotland desperately needing a victory to breathe life into their ailing RBS 6 Nations campaign. A narrow victory over Italy and agonising defeat to France has ensured their mixed season continues. Heaslip insists they can ill-afford to keep making mistakes.
"We've evolved into playing this new type of game. We split a lot of teams wide open and caused them problems. But our own mistakes punished us, stuff like turn overs and easy penalties," said Heaslip.
"That has happened less frequently in the Six Nations but it has happened one or twice. The standard of sides we're playing punish you for mistakes.
"You might get away with it once or twice in club rugby, but international rugby is pretty ruthless.
"We are on the brink of doing something really, really good.
"We're showing that we can score tries against very good teams. We just need to cut out the mistakes we can control."
