Powerful Leinster and Ireland flanker Sean O'Brien has said he would consider a move to France at the end of the current season.
O'Brien has been a stand-out performer for province and country in recent years, earning him a call-up to Warren Gatland's Lions squad for the tour of Australia this year.
However, with his contract at Leinster up at the end of the season, speculation over his future is rife, with Top14 clubs Racing Metro and Clermont reportedly among those interested in gaining his signature.
With such lucrative potential deals on the table, O'Brien has acknowledged that he would have to seriously consider how a change of scene may benefit him.
"It is something that I would have to consider," O'Brien told Newstalk.
"At the minute, I am playing for Leinster and Ireland and I love playing for both sides. That's where I want to be. I have to take into consideration my best interests. I have to look after me. There is a bit of a grey area there."
Former team-mate Jonathan Sexton left the province to join Racing Metro earlier this year, and should O'Brien decide to make the trip across the channel, he may be joined by fellow Leinster back-row, Jamie Heaslip, whose contract is also up at the end of this season.
Sexton told RTE that despite his move, he feels Irish rugby would benefit more from keeping its big-name players in the country.
"It might sound contradictory because I left to play elsewhere," said Sexton.
"But I hope guys like Jamie and Sean get tied into long term contracts in Ireland, even if it was a possibility that they'd be joining the club that I am at. I'd still hope that they stay here. It's better for Irish rugby if they stay here."
The fly-half was left frustrated by his own contract negotiations at Leinster, and has urged the Irish Rugby Football Union (IRFU) to act quickly to secure the services of O'Brien and Heaslip.
"There are some very important players to Irish rugby who are out of contract at the end of the season," said Sexton.
"I hope they sit down with these guys and get it sorted before it gets messy. They could do it now before there are other clubs sniffing around. They could have done it a few weeks ago."
