European Rugby Cup president Jean-Pierre Lux says that Mourad Boudjellal's Heineken Cup vs Super Rugby Champions match is an impossble project.
Lux was responding to Toulon President Mourad Boudjellal who says that he plans to make an announcement on a "Rugby World Club Cup" on Thursday.
Lux says that teams who contest the Heineken Cup are forbidden to play a match against other teams outside of ERC organised events using their title as European Champions.
The ERC president said that if Boudjellal tried to "force" the game into being played Toulon will not be permitted to play a game as a champion of Europe.
"Under the agreement for participation in the European Rugby Cup (which) they signed before the competition, as part of their participation in the European Cup the clubs do not have the right to play such a game with title of European Champion. "
"Especially against the winner of the Super 15, it is stated in the agreement," Dax told Sud Ouest.
Lux said he understands the reason why Boudjellal wants to organise the match but he says that does not have the authority to arrange such a match.
"I totally understand that he wanted to do something, but Mr. Boudjellal does not have the latitude to organize such a game."
Lux revealed that a match between the winners of the Heineken Cup and Super Rugby could not be played without the approval of both organisations.
The ERC President said that they had been in talks with SANZAR over such a match for a long time but finding a gap in the calendar remains the stumbling block.
"It's a good idea" said Lux. "The Four Nations (Rugby Championship) begins two weeks after the final of the Super 15 and I do not see the New Zealand Federation, for example, allowing a third of their players to go play a game in Europe on the eve of the Four Nations. "
IRB President Bernard Lapasset said in his personal capacity that he had received more than a hundred proposals of a match such as this but for it to happen you need a year with 60 weeks.
Rugby fans across the globe should not give up hope for this match just yet as there has been much talk in recent months of a move - possibly from 2016 - to align the Northern and Southern Hemisphere Rugby calendar which could free up space for this match.
