Sean O'Brien in bid to face All Blacks

Ireland flanker Sean O'Brien intends to use his full Test debut to convince head coach Declan Kidney he should start against New Zealand.

O'Brien has replaced David Wallace at openside for tomorrow's autumn international against Samoa at Aviva Stadium as one of ten changes to the side edged by South Africa.

The 23-year-old made his debut last November and has been limited to just three Test appearances from the bench amid fierce competition for places in Ireland's back row But, having been given his opportunity, he intends making the No 7 jersey his own.

"This is a good chance for me to show Declan how good I am. Samoa are a tough side and I'm looking forward to it," he said. "Hopefully I will have a good game and then selection will be up in the air the following week against the All Blacks. I want to get my role right and have a good game.

"The competition in the back row is unbelievable. I'm the youngest but at the other end of it, I'm eager and want to prove a point.''
