England's Premiership rugby clubs, emboldened by the "historic" agreement that has given them a central role in running next season's new European competitions, are set for three more battles with rugby's governing bodies.
The clubs are demanding 14 million ($27 million) from the Rugby Football Union as compensation for the disruption caused by next year's World Cup in England and Wales.
And the clubs, having paid tribute to the RFU's chief executive Ian Ritchie for smoothing the new European Professional Club Rugby (EPCR) accord, are set to test the resolve of the world governing body, the International Rugby Board (IRB), with plans to create a World Club Cup in June 2018.
The month-long tournament, which has been discussed with broadcasters Sky in the UK and Supersport in South Africa, would see the eight quarter-finalists from the European Champions Cup meeting eight southern-hemisphere teams from what by then will be the Super 16.
A key aspect of the European accord that will see a 20-team Champions Cup replace the Heineken Cup next season is that the national unions have nine seats on the 18-strong EPCR board.
