Rob Kearney believes captain Rory Greatest is the”glue” that holds Ireland together however a farewell for him and head trainer Joe Schmidt isn’t essential against Wales on Saturday.
Greatest, 37, will play his final home game at the Aviva Stadium on Saturday against Wales and will retire from baseball after the World Cup in Japan.
Schmidt will also step down following the tournament after six years at the helm, where he’s mastered three Six Nations titles.
Kearney played down the importance of a send-off for the set.
“Obviously it’s important but it is not in the forefront of our thoughts,” he said.
“Performance is enormous for us and even if you scale back the performance, it’s putting it into cubes; the first 10 minutes, the second 10 minutes, etc.
“We actually should ensure we are firing whatsoever cylinders for that very first week, [of the championship ] so that this weekend is a significant step for us.
“And then you get to enjoy and feel pleased with giving Joe and Rory the huge send-off.”
Best, who played his game in May for Ulster, will get his 120th cap against Wales – which makes him the capped player in the history of Ireland – behind Brian O’Driscoll and Ronan O’Gara.
“It’s huge, is not it? And sometimes I think it will get a little helpless,” Kearney said on Best’s leadership ahead of Ireland’s final World Cup warm-up game.
“A number of the momentous victories we’ve had as a team have been beneath Rory. He’s a brilliant leader, he’s the glue that brings the group.
“Again, he’s a guy who’s training well and I am sure he’s very eager to get out there and also show he’s still exceptionally capable of generating big performances, even at his ripe old age”
Ireland returned to winning ways last weekend when they have been comprehensively beaten by England 57-15 at Twickenham, edging out Wales 22-17 in Cardiff on Saturday.
