The worst thing the Six Nations can do is change, according to former Leinster coach Matt Williams.
There's been speculation that world champions South Africa could be added to the competition from 2025, with reports that Italy could potentially be removed.
South Africa confirmed their commitment to The Rugby Championship for the next three seasons earlier this week and it was claimed that the Springboks held talks about a possible switch to the northern hemisphere competition.
But Six Nations Rugby and investment firm CVC have poured cold water on those reports.
"Six Nations Rugby, comprising the six Unions and Federations and CVC, wish to confirm that they are not entertaining any discussion nor developing any plans to add or replace any participating Union," they said in a joint statement.
"All its energy is focused on the current strategic discussions regarding the July and November international windows and structure of the global season, and to ensure a positive outcome for the development of the game."
Speaking on Monday Night Rugby on Off The Ball, former Leinster coach Matt Williams said that the 'law of unintended consequences' comes into play if the organiser try to mess with the format.
"Everything that makes this tournament beautiful and unique, is that officials haven't buggered it up by changing it.", Williams said.
"It's a European game."
"If they bring South Africa in, you have got the law of unintended consequences just banging on the door. What will happen?"
"Super Rugby is being decimated by ridiculous decision making by officials who probably thought they were doing the right thing."
