Thank you for your replies. But things are maybe going to change in the champions cup. Many French teams have financial difficulties, and too many are supported by the same administrative region (Toulouse, Castres, Montpellier are in Occitanie, as well as 2nd division teams : Béziers, Montauban, Colomiers, Perpignan, Carcassonne). The situation is quite the same as in the UK, if you don't have a private funder (Pierre Fabre for Castres, Altrad for Montpellier, etc...) you are nothing. In March, maybe the Biarritz Olympique will simply disappear, that's a great wave in the French rugby. Even Toulon had the chance to find a new funder.
But finally, look, Boudjellal hired Botha, Wilkinson and so on: 3 stars in champions cup. Some years after, Boudjellal has less money... and where is Toulon now? Sadly, money is almost everything. So I hope to see the alignement of championships formats in order to see maybe more equity for the european cups.
