Jamie Osborne says he is "confident" playing in any position for Ireland in Saturday's Six Nations game with France.

Osborne was named at full-back in place of Hugo Keenan in Ireland's win over Wales but has also featured at centre or the wing.

The 23-year-old bounced back from a nervy start in Cardiff to score a crucial try as Simon Easterby's side edged a tight contest.

"It definitely helps I've played a couple of positions," Osborne said.

"I'd be confident in any place I end up going. If you do your role well and perform well then the coaches will see that.

"When the team performance goes well I think everyone benefits from that."

The game with Antoine Dupont's France in Dublin has been billed as a potential title decider.

The hosts are unbeaten and aiming for an unprecedented three Six Nations championships in a row while France can take control of the tournament with victory in Dublin, which could move them to the top of the table ahead of the final round of fixtures.

"It's a huge challenge but everyone is looking forward to it," Osborne added.

"We know how strong they are and we have to be at our best to beat them."

While Ireland had moments of difficulty in Cardiff last time out, Osborne said the team "will learn from it" ahead of the game with France.

"The first half wasn't how we wanted it to go. There were a lot of errors, including from myself, but we bounced back from being five points down with a man in the bin, we managed to get back into the game.

"Probably not the game we were expecting to play before the game but we put pressure back on them. I think we learnt a lot about ourselves in the second half."
