Toulon president Mourad Boudjellal has promised to walk away from the club if they don't finish in the top six of the Top 14 this season.
The comic book magnate has transformed Toulon since arriving at the club back in 2006 and they have won the last three European Cups.
However they have made a slow start to the season, losing for the fourth time in seven matches on Sunday at Grenoble, and are currently eighth in the league.
Only the top six qualify for the play-offs, as well as the Champions Cup, but with a host of World Cup stars on their way, including Ma'a Nonu, Duane Vermeulen and Quade Cooper, Toulon should turn things around.
However Boudjellal admits he made some mistakes as Toulon struggled to cope without their test stars.
"I'm responsible. I managed the World Cup period badly. We didn't know which players were leaving and there weren't many players available for two or three months," he told Rugbyrama.
"I misjudged this period. And if because of that, we don't finish in the top six at the end of the season, there's no reason for me to stay at RCT.
"I'll assume my responsiblity, it will mean that I've become a trumpet and that I'm more harmful than anything else for the club.
"When I say something, I stick to it and suffer the consequences. I have to go. But I don't see any reason why we won't be in the six, you will have to put up with me a little longer."
