Murray relishing O'Gara link-up
More than a century of caps may separate Conor Murray from Ronan O'Gara but Ireland's rookie scrum-half is still comfortable barking orders at his veteran Munster team-mate.
Murray only broke into Munster's first team this year and has yet to play in the Heineken Cup, but has travelled to the World Cup with a genuine chance of making the Test XV. Should he win the race for the number nine jersey, Murray could find himself operating alongside the player he admired most as a youngster.
And Murray said: "You have to be able to bark at someone like him during games. He does the same to me and it's a good relationship. You have to be comfortable shouting at players, even if it means you must push yourself to do that."
He added: "You have to roar at them if they're doing something wrong or you want their attention.
"It's not the time to be quiet on a rugby field, especially at this level."
Two years ago Murray was helping AIB League club team Garryowen escape relegation, but his meteoric rise has now thrust him onto rugby's highest profile stage.
A beneficiary of Tomas O'Leary's collapse of form - his provincial colleague was omitted from the squad - he convinced Declan Kidney that he deserved a ticket to New Zealand with his assured debut against France last month.
Each of the three scrum-halves in the squad offers something different and Murray hopes it is his style that is preferred by Kidney for Sunday's opener against the USA.
"I have a competitive nature. There are two other scrum-halves here and we're all battling for that one place," he said.
"I want to do as well as I can. I want to get some game time and don't want to be a passenger. I'm not here for a holiday, I want to contribute to the team's effort to do as well as we can."
