Dan Bigger was also linked yesterday. Im not sure if they have a salary cap in Pro D2??
Its a good question - and I don't know the answer.
It wasn't really relevant to Beziers before though as their income was fairly modest. From memory, the main sponsor (or owner) used to give them a million Euros per year. I think that the city matched that. They had quite a few smaller sponsors. E.g., their shirts were from Shilton - who are a fashion brand based in Beziers. The stadium has loads of small adverts - and the in stadium big screen TV runs adverts during the games. They play at the public stadium (Stade Raoul-Barrière, formerly Stade de la Méditerranée) which is bigger than they need.
Beziers is a rugby mad area. Historically, they were the best team in France during the 1970's to mid 1980's. Their youth team won the French championship last season.
It would be nice for them to get some success again (- as long as it doesn't push up ticket prices :-) )
