Ireland vice-captain Jamie Heaslip could be about to follow Jonathan Sexton to the Top 14 in the summer as he enters into advanced talks with Toulon.
Contract negotiations with the IRFU have stalled in recent months and the world's richest club have swooped in.
The Naas man, who became the highest paid player in Ireland when he signed a a three-year deal in 2011, is in France to thrash out a possible move to the continent.
Montpelier are also talking to Heaslip about a possible move.
It is understood that Heaslip wishes to stay at Leinster and further talks with the IRFU are expected.
Current European champions Toulon, owned by the comic publisher Mourad Boudjellal, would be an enticing option for any player.
There are also fears that if Heaslip moves to France it could complicate the IRFU's attempts to tie down Paul O'Connell, Sean O'Brien and Keith Earls who are also out of contract at the end of the season.
