The Crusaders backs coach has been linked with a role with Les Bleus for the tournament in Japan later this year.

Former Ireland five-eighth O'Gara, who spent four seasons working for Racing 92, says he remains committed to the Super Rugby champion. 

"There were one or two approaches from an agent, that's as far we've got," O'Gara said on New Zealand radio.

"As anyone knows I have an amount of work to do here, which is really important to me, and if there is anything, Razor [Crusaders head coach Scott Robertson] and the Crusaders would be the first to know about it."

He added: "It's not a distraction. These are all conversations that happen. Next week it will be someone else."

Brunel has come under increasing pressure after another disappointing Six Nations for France, which delivered only two victories.
