Ireland international Iain Henderson believes his team's victory over All Blacks in Chicago last year will instill belief in the British and Irish Lions in their upcoming tour of New Zealand in June.
The win which was considered as one of the biggest achievement in Ireland history also brought an end to the 18-match winning streak of Steve Hansen's men and Henderson, who missed the game, recalled how his teammates "got in their faces, under their skin and disrupted them from their usual game".
"The boys over in Chicago got under the All Blacks' skin," said Henderson, who assembled with 13 of his Lions colleagues for a first day of training in Wales on Monday.
"They made them cough up a loss. It was definitely a performance put in where the boys got in their faces, under their skin and disrupted them from their usual game.
"It will be what we are looking to do out there, not beat them at their game, but at our game.
"I am not sure how Gats (Lions head coach Warren Gatland) goes about things. We might look at it (Ireland's win against New Zealand) to get round the All Blacks.
"He will know their players well and use his knowledge of them to our benefit. We are looking forward to seeing an awful lot more of what they are showing and how they are looking to play.
"We need to get this squad gelled together first, and get those first few games out of the way."
When New Zealand visited Aviva Stadium for the return fixture, Henderson was among the replacements as he saw Ireland go down 9-21. The 25-year-old expressed disappointment on missing out on what would have been a very special achievement for the Ireland team.
"It would have been incredible to beat them again after doing it for a first time.
"We looked at the game and we had chances - we felt we put them under pressure and we showed Chicago was not a one-off.
"We didn't do ourselves justice, the boys in that team wanted to back up two wins. But it can give us confidence, certainly.
"The All Blacks, as talented as they are, have their weaknesses which can be exposed."
