The friendly with Argentina signifies a double coup for Keane as the 30-year-old will win his 100th cap, becoming only the fourth to do so for the Republic.

Keane will also lead out the boys in green into their new Aviva Stadium home for the first time, a 50,000-seater venue built at a cost of £350million.

Only goalkeeper Shay Given and midfielder Kevin Kilbane, both with 103, and former defender and manager Steve Staunton with 102, have more caps to their name.

Keane, though, has an astonishing goalscoring record, plundering 43 from his 99 appearances to date, more than the total combined for the next two players on the Republic list - Niall Quinn and Frank Stapleton.

"It's a great achievement to get to 100 caps, especially with the occasion of the new stadium as well, it's history in the making," said goalkeeper Given.

"With it not being a competitive game, it's also great for Robbie as he can enjoy it more.

"But looking back, he's been huge to Ireland over the years, with a goalscoring record at international level that stands alongside some of the best players in the world.

"Sometimes we forget that and underestimate how important Robbie is to the team."

As far as strike partner Kevin Doyle is concerned, Keane compares to some of the greats of Irish football such as Liam Brady, Johnny Giles and Paul McGrath.

"He's won more caps, scored more goals, he's captain, has played and scored in World Cup finals, so he is ranked as high as those," said Wolves forward Doyle.

"Anyone who gets 100 caps, first of all it shows how much they love football, and then there's his goalscoring record of a goal nearly every two games.

"It's a privilege to play with him. In fact, I'm lucky to be able to play with him.

"He is someone I can learn from, to see how he prepares, how he looks after himself, how he gets into his positions to score goals.

"He's only 30 as well, so he has the chance to win plenty more caps and score plenty more goals too."

Given will win his 104th cap now he is fully fit after recovering from surgery to repair the left shoulder he dislocated at the end of last season whilst for playing for Manchester City.

That proved to be a bitter experience at a time when City were vying for a top-four finish and Champions League football.

"I was disappointed to miss out on the last three games," added Given.

"But these things happen. If there was a good time to have it I suppose it was then because there was only a week to go in the season and I had all summer to recover.

"To be honest I've worked pretty hard all summer, and I'm delighted to be fit for the new season."

In contrast, Doyle is a doubt with a calf injury whilst defender Richard Dunne has a knee problem.
