Cape Town - Montpellier are hoping to tempt CJ Stander after offering the Ireland international €840 000 (R12.6m) a year, according to the Irish Examiner.
The back-rower's contract expires at the end of the season and, although the Irish Rugby Football Union (IRFU) are confident of keeping hold of the South African-born player - the French club are looking to entice Stander with a huge offer.
Negotiations are ongoing between the 27-year-old and the governing body, with the Examiner claiming that they have tabled a bid which includes a basic salary of €400 000 per year, but Montpellier's proposal could complicate matters.
While Ireland were dealt a blow with the departure of Simon Zebo, Peter O’Mahony and Tadhg Furlong signed new contracts last week and Munster will hope that Stander follows suit.
Stander, who was born in South Africa and started his career at the Bulls in 2010, has been on Munster's books since 2012.
The loose forward qualified to play for Ireland three years later and has since gone on to play 18 Tests for his adopted country.
He also boasts one Test for the British and Irish Lions, having come off the bench in the drawn final Test against New Zealand in Auckland in June.
