Any break-a-way from the existing is going to be difficult, as has been proved by the time the 'super league' has been being discussed.
Any break-a-way would mean the break-a-way clubs would only initially have the game incomes.
The break-a-way clubs wouldn't be eligible for their home country associations cup games for a starter.
Any television coverage could be hampered by each country's association giving the television stations an ultimatum of, if you want our teams on your tv station, you cannot have the 'super league'.
No I'm afraid there is too much against any break-a-way succeeding financially for it to happen.
I dare say there will continue to be discussions about it every few years, especially when the ruling bodies do something that the clubs disagree with but, thats as far as it will ever get.
