RUGBY UNION: All Blacks coach Steve Hansen has mooted the possibility of the Rugby Championship winner and the Six Nations champion going head to head in an annual clash.
Hansen also said the northern hemisphere v southern hemisphere rivalry could stretch down to club level.
Talks have already taken place about how rugby can move forward after the next World Cup in Japan, with those discussions including aligning the playing calendars on the opposite sides of the world.
Hansen told the Daily Mail an historic agreement of dates between officials would send the game "through the roof”.
"It's a no-brainer,” he said. "You've got to say, 'What's best for our product so we can keep attracting people to come and watch it?'
"First, our players need a decent pre-season. You'd play club competitions simultaneously.
"We could have the European Cup winners play the Super Rugby winners and the Six Nations winners play the Rugby Championship winners.
"We need some goodwill to sort it out.”
