Toulon president Mourad Boudjellal says he is serious about an approach he has reportedly made for the reigning European champions to join the Aviva Premiership.
The outspoken Toulon chief told www.lequipe.fr that his club's Premiership presence would offer "a huge added value".
Boudjellal has had an ongoing and often bitter battle with organisers of the Top 14 - France's premier domestic competition - about matters such as the salary cap.
Toulon's expensively-assembled squad is packed with world stars like Bryan Habana, Matt Giteau, Leigh Halfpenny, Quade Cooper, Juan Martin Fernandez Lobbe and Duane Vermeulen.
England superstar Jonny Wilkinson, meanwhile, inspired them to a first European title in 2013, with that trophy being retained the following season and in 2015.
Victory over Bath at the Recreation Ground on Saturday should secure a Champions Cup quarter-final place and keep them on course for an unprecedented fourth successive European crown.
Speaking about what will be widely viewed as an audacious and improbable move, Boudjellal said: " I wrote for a contact.
"If this is not possible the next season, maybe the one after that.
"For them (the English), besides a big first, it would be a huge added value. And I'm serious in my approach."
