For the past 10 years, rugby's world rankings have barely been mentioned by anyone – the All Blacks sat at the top and no one had a problem with that. But Wales' ascent to the top of the rankings two weekends ago has now made it one of the most keenly discussed topics.
Suddenly there has been swathes of criticism of the system, which has given Wales and Ireland the opportunity to climb to No1 over the past few weeks, a status they will contest again this weekend when they face each other in Cardiff.
Agustin Pichot, the vice-chairman of World Rugby, has now weighed in on the debate, claiming it is "ridiculous" how Wales can climb to No1 despite last beating the All Blacks in 1953.
The former Argentina captain also said the ranking system does not treat either Italy or Los Pumas fairly as they have tougher schedules from respectively being in the Six Nations and the Rugby Championship.
