A radical eight-team Six Nations format has been proposed in response to South Africa’s bid to join Europe’s annual competition.
Instead of playing against every team every year, they're exploring using the same weekends with two pools of four. The other team likely to be added would be Georgia or another up and coming European nation.
Reports suggest there would be three group games, two semi-finals and a final with teams rotated over a period of two or three years to ensure everybody plays everybody.
Such changes to the tournament would not come into effect until 2025 at the earliest.
Italy's abysmal record in the competition has been well documented, with 36 defeats on the spin moving some to question whether they deserved a place among the European elite.
National reports stated that the Springboks were set to be welcomed into the fold possibly at the expense of the Italians, but this was quickly rubbished by Six Nations chiefs.
Erasmus, writing in his Daily Mail column, said he would still love for the Springboks to be involved in the tournament but only if it expanded .
He said: "Italy beating Wales obviously closed a lot of arguments about them being kicked out of the Six Nations. Let's hope they go from strength to strength now, then it's great for rugby.
I would still love to see South Africa in the Six Nations, but I think that would only be a scenario if the competition expanded to seven teams"
"I’ve been fortunate to have refereed some tremendous No.8s during my career but Sergio is tops. He’s such a talented player and rarely has a bad game."
#4.Thierry Dusautoir (France)
Owens wrote: 'My choice as the best skipper I encountered may raise a few eyebrows, but what a captain Dusautoir was. He unfailingly put his body on the line throughout his career — recall the 38 tackles he made when France knocked the All Blacks out of the 2007 World Cup — led by example and understood the game very well.
"Also, he was exemplary in the way he conducted himself.
"There were never any complaints from him over refereeing, not even when borderline decisions went against France. When his team were crushed 62-13 by New Zealand during the 2015 World Cup, he wasn’t tempted to blame anyone.
"He acted as a true leader should act."

Owens wrote: "Not only is he one of the greatest centres in the history of rugby union but he’s a fantastic man off the field as well. O’Driscoll has been a wonderful ambassador for the sport and a real leader. He always respected referees and set the right example for others to follow.
"A legend of the game who conducted himself superbly, on and off the pitch."
#2. Richie McCaw (New Zealand)
Owens wrote: "If anybody had to pick the greatest player in history, it would surely be a difficult choice between him and Gareth Edwards.
"How McCaw managed to put his body on the line and sometimes the wrong side at rucks for so many years at flanker is incredible."
#1. Shane Williams (Wales)
Owens wrote: "When people ask me who is the best player I have refereed it’s pretty much an impossible task to pick one because I’ve been lucky enough to take charge of so many greats.
"But if I’m pushed, I would pick Shane for what he achieved after coming from football at 17 or 18 years of age.
"He was in the mould of Gerald Davies in how he left defenders gasping for air as he beat them with those dazzling sidesteps."
