Joe Schmidt has backed “big moments player” Peter O’Mahony to deliver again when it matters most in Saturday’s World Cup quarter-final against New Zealand.

British and Irish Lions flanker O’Mahony has held off the challenge of the in-form Rhys Ruddock to start Ireland’s last-eight battle with the All Blacks in Tokyo on Saturday.

O’Mahony might not top many tackle or carry counts, but head coach Schmidt insisted the 63-cap Munster back-rower remains vitally important to Ireland’s approach.

“Andrew Conway has been very good too, and so the outside backs have been a bit of a conundrum.

“We’ve tried to add up as best we can the combinations we think that will best serve us in this fixture.

“I think the unfortunate thing about selecting a 23 to play the All Blacks is that they can play very well and still not get the result. That’s the quality the All Blacks have.

“But these players, they’ve had some very successful experiences together and contributed to a fair bit of history for us.

“You can’t go out against the All Blacks and accept that you’re second fiddle.

“You’ve got to go out and put your best foot forward.”
