Outgoing Ireland manager Mick Kearney says UFC champion Conor McGregor is the motivational speaker at the top of the players' wish-list.

Kearney’s tenure will come to an end following the Autumn Series finale against Australia today (5.30pm, live on RTÉ Radio 1 and RTÉ2), with former Ireland international Paul Dean taking over as team manager.

One of the duties of the role is to entice guest speakers to address the group, giving a better understanding of how they achieved their success and overcame setbacks.

High achievers from the world of business and sport have spoken in the Irish camp through the years, with Mark Pollock revealing he had encouraged Joe Schmidt’s charges to “turn the impossible possible” in a stirring speech prior to the historic win over New Zealand in Chicago.

"The one person they really want to get in now is Conor McGregor"

Kearney has introduced a highly impressive list of speakers in his tenure, but told The Daily Mail that there is one sports star that the players really want.

"I organised Usain Bolt, Rory McIlroy, Barry McGuigan, Niall Quinn, Sonia O'Sullivan, lots of good sportspeople, to talk to the lads but the one person they really want to get in now is Conor McGregor," he said.

"They felt I might be able to pull that off before I left. I've a connection through someone I know to his coach John Kavanagh.

“If I can assist when I'm gone I will do that, but as I said to Paul I have to leave somebody for him to get because we have got a lot of the good ones in.”

Seán O'Brien and Jared Payne meanwhile are late doubts for the clash with the Wallabies.  

Munster flanker Peter O'Mahony has been drafted in to cover O'Brien and already had Rory Scannell on hand to cover centre Payne.

Ireland's assistant coach Andy Farrell has insisted both men had merely carried "lower-limb tweaks", and so sat out Friday's captain's run training session.

A decision on their fitness is expected in the afternoon.
