Johnny Sexton is certain to travel to face the All Blacks in July and it is up to Joey Carbery to convince Andy Farrell that he deserves to start in at least one of the Test games.
That's the view of Ronan O'Gara, who concedes that he can't make a solid judgement on Carbery's standing with Farrell because he doesn't know what goes on day by day in camp Ireland.
What the Munster and Ireland great is certain about is that Ireland will be facing a "fresh" New Zealand team coming off their Super Rugby season that will be "hungry" to regain reputational ground after November's northern hemisphere losses to Ireland and France.
